Vermona PERfourMER MKII
– the new Four-Voice?

It doesn’t happen too often that you play a brand new analog synthesizer for the first time and everything is perfect, just the way it should be. But this was the case with the PERfourMER MKII.

Vermona Quad Analog Synthesizer

Quite a few modern synthesizers try to con us. They make a musician’s life more difficult than necessary, because …

Possibility no. 1: The synthesizer contains presets of medium quality … average sounds (some good, some really bad) making it difficult to realistically evaluate sound potential. You simply can’t tell what that synthesizer really sounds like …

Possibility no. 2: You’re faced with mediocre hardware. With wobbly and fiddly knobs. With buttons and switches placed way too close to each other (like sardines in a can). With insufficient control elements that significantly reduce the joy you could be having with the instrument.

Vermona Quad Analog Synthesizer

Possibility no. 3: The synthesizer lacks certain important features. Maybe MIDI is missing (if CV/Gate is installed) or CV/Gate is missing (if MIDI is installed). A modern studio containing both analog and digital components needs both communications busses!

These are just a few of the reasons why a complete and well-designed instrument such as the four-channel Vermona PERfourMER synthesizer should not be taken for granted.

Interestingly enough, it’s rarely the sound which gives cause for criticism. Analog circuits simply sound good (the real reason for the renaissance of analog synthesizers).

Ye Olde Rule says: good sound alone is not enough. And so it’s the rare, the very rare case when it’s love at first sight between the instrument and the musician.

That’s the secret of the congenial relationship between the PERfourMER and myself. The very first notes I played brought back memories of the Roland Jupiter-4 (without chorus): that dry, classic Roland analog sound of the vintage years.

Appetizing, in a word.

There’s the wonderful pulse wave and each of the 4 voices sounds somewhat different. It’s possible to create this vivacity on purpose with the PERfourMER – with just a few adjustments – in contrast to the Jupiter-4, where this can be an unintended side effect.

And then there’s that unison-mode, which stands for rich sonority. There are no superflous functions on the PERfourMER. In short time you’ll be best friends and – this is the hammer – you’ll be knee deep in the creative process from the very beginning.

It goes without saying that the PERfourMER MKII is first and foremost an independent instrument, whereby the filter resonance has its own special character.

Just for comparisons, and as a sort of reference, consider this: I would call the PERfourMER a combination of a Roland Jupiter-4 and Oberheim 4-Voice. The first association pertains of course to sound, the second to technical matters. 4 SEMs à la Oberheim and 4 parallel synthesizers à la PERfourMER MKII are simply one and the same concept, especially since the crucial Play Modes are present in both cases.

The sum of all the small things

Excuse us if we repeat ourselves, but good sound alone is not enough. The PERfourMER MKII will wow you at a lot of different levels.

Let’s start with the outside. Solid casing, good knobs (not a single knob wobbles), a pleasant, subtle resistence to the touch, large sockets, clear labelling.

MIDI, Mains In and a proper power switch.

MIDI, Mains In and a proper power switch.

Another point to be kept in mind is the power supply. This can be a tiresome subject as we recently mentioned in the course of one of our rare criticisms of the John Bowen Solaris. The PERfourMER has found an ideal solution, in an old-fashioned sort of way. The PSU is built-in. All you need is a regular 3-pole power cable. Just turning the instrument on has a reliable, comfy feel.

There’s MIDI (of course), and an option for CV/Gate. Whether you use the Alesis Andromeda as a master keyboard (as in our test) or the analog drum sequencer TAMA TSQ1000 with 4 triggertracks (as in our test): the PERfourMER is very cooperative and easily controllable.

Also, control elements are well dimensioned and well spaced (fat fingers are no problem here). And then, the four parallel synthesizers are intelligently arranged, with a few additional small technical goodies located on the side.

Optional extra: CV/Gate inputs.

 White  Hot noise – a question of character?

This absolutely noble concept (yielding an equally noble analog sound) goes hand in hand with a special „specialty“: we have to put up with a little static in the audio path. It’s not bad and let’s not lose our perspective here. Think back to the golden days of analog technique. A significant aspect of the Jupiter-4 sound (not to be eliminated), for example, was noise, partly thanks to the Roland stereo chorus.

Korgs PS-3100 is a little “noisy” and Rolands Jupiter-8 has a permanent buzz in the audio signal. And yet, no one would think to criticize these instruments for having a bad sound.

I thus gladly accept the subtle „hot noise“ of the PERfourMER MKII as a characteristic of its very characteristic sound. After all, we are talking about an analog instrument …!

Noise in the audio path increases corresponding to adjustments in the filter resonance settings. Well, actually, to be exact, the overall volume increases. This behaviour is a little weird, which is why I contacted Vermona and asked them for an explanation. Thomas Haller kindly answered immediately.

„That’s correct. The amount of audio level increases corresponding to higher resonance settings. This is due to our special filter design. In most cases, there’s a loss in volume when filter resonance is raised. By modifying the filter design, we have compensated for eventual volume loss. Filter output level increases in direct relation to resonance settings.“ (Vermona)

So, let’s forget about the „hot noise“. The bottom line is: this is not important. We absolutely recommend the Vermona. Its sound is a delight. Here’s a good place to „take a hear“ of the 45 minutes of PERfourMER MKII audiofiles attached to this review. Press „Play“.

Now back to business.

Discrete analog

The PERfourMER MKII is completely „discrete analog“ (with one exception: the LFOs). It contains …

4 VCOs

  • waveforms: sine, triangle, pulse, saw, noise and EXT.
  • octave ranges 4-8-16-32, further HI and LO (which turn the oscillator into a wide-range LFO).
  • fine tune
  • glide
  • EG modulation (+/-) … for those typical electronic drum sounds.
  • LFO modulation and pulse width modulation

The pulse wave is extremely beautiful. It reminds me of the Jupiter-4 and other early Roland synthesizers. But it’s even more than that! PERfourMER’s pulse width modulation allows for unbelievably “fat” sounds, since there’s a separate LFO for each of the 4 oscillators. PWM can also be effected by the modulation wheel of your master keyboard (independently switchable for each synthesizer channel, of course). PWM by LFO is especially interesting. The sound is capable of fading completely (0% pulse width). One of the best PERfourMER patches is a 4-VCO pulse tone with independent LFO modulation. Each of the oscillators fades in and out, depending on the channel’s LFO speed and PWM degree. PWM by modulation wheel, on the other hand, is less dramatic. It doesn’t seem to reach all the way to 0% pulse width, which is a bit a shame …

The frequency settings LO and HI are worth mentioning. (In this case, the term OCTAVE is of course not correct). Both settings disconnect the VCO from keyboard voltage and turn it into a free audio generator, the frequency of which is adjustable by the TUNE knob. Frequency ranges from sub-audio all the way up. LO is primarily responsible for sub-audio-frequencies and can be used as an LFO.

Synchronization

With 4 VCOs, oscillator-synchronization is an important aspect which Vermona has kept in mind. Each VCO can be synchronized to the preceding oscillator: VCO 2 to 1, VCO 3 to 2, VCO 4 to 3. Good stuff. Synchronization at its finest.

Crossmodulation

The same principle applies to crossmodulation. Each oscillator can influence the next. The crossmod-knob is one of those little goodies so conveniently placed at the left side of the front panel.

VCO Out / EXT In

Those looking for a „naked“ VCO sound will be glad to hear that there is a VCO OUT socket with every synth channel. This has to be of interest to owners of modular systems, since they can run the pure VCO material from the PERfourMER through other modules (such as multimode filters, etc.). A small, but weighty detail.

VCO-Out / EXT-In jack. The PERfourMER is a 4-channel filter bank, too.

VCO-Out / EXT-In jack. The PERfourMER is a 4-channel filter bank, too.

On the other hand, you’re able to feed an external audio signal into each PERfourMER channel. Which means this instrument is a fourfold filter bank. Not a bad deal.

4 VCFs

The 24dB low pass filter is of elite quality and just as we like it: snappy sounds resulting from strong self oscillation at high filter resonance.

Filter modulation is possible via the envelope (+/-), the LFO or aftertouch (MIDI). Keyboard-tracking is fixed at 0/50/100%.

Filter FM

As with the „cross“-crossmodulation between VCOs, each filter can be influenced by its preceding oscillator. The epitome of filter FM. It goes without saying that metallic and other experimental sounds can be easily created.

Compact VCF- and LFO-area.

Compact VCF- and LFO-area.

LFO

  • waveforms: saw, pulse, sine and S/H
  • frequency range from 0,05 to 250 Hz

Small is beautiful. The LFO alone has practically everything you need. Those of you who miss a voltage control feature will find this an option with the VCO in LO (or HI) mode.

LFO synchronization and phase

Let’s not forget these two LFO features. The low frequency oscillator serves as a modulation source for VCO and VCF, as we have said. A superficial glance at the panel might lead to the false conclusion that the 4 LFOs can not interact with each other and that only positive modulation is possible. But that’s wrong …

The synchronization switch is the one extra on the left panel that we haven’t spoken about yet. LFO 2, for example, can be linked in parallel to LFO 1. The latter remains responsible for the combined speed, while LFO 2 phase is adjustable (from 0 to 180°).

In LFO sync mode the speed knob acts as phase knob.

In LFO sync mode the speed knob acts as phase knob.

In position „0“ the two LFOs have the same phase. Turning the phase knob to 180° inverts LFO 2 so that it runs contrary to LFO 1. Beautiful. Intermediate positions (in which one LFO lags a bit behind the other, etc.) also yield interesting results.

Since there are 4 LFOs at your disposal in addition to the 4 VCOs/LFOs in LO/HI range, it is obvious that the PERfourMER MKII isn’t just capable of little niceties, but is good for very surprising effects. The individual synthesizer channels of the PERfourMER are capable of communicating with and reacting to each other. Indeed, the instrument totes high experimental potential.

Last but not least, the LFOs can be synced to MIDI clock.

All EDIT parameters may be activated independently for each synthesizer channel.

All EDIT parameters may be activated independently for each synthesizer channel.

Envelopes

Each part of the PERfourMER has its own ADSR envelope. The attached audiofiles give plenty of evidence that the instrument can be snappy. But I also find the optionally long attack- and release-times attractive. In LEGATO mode, the envelopes only trigger when a new key is hit. This function, too, is individually adjustable for all 4 synthesizers …

VCAs

Each VCA is either regulated by the above-mentioned envelope, by an organ-type EG (100% sustain), or by a HOLD function („ON“).

In addition, VCA modulation can be effected via velocity. As with all else, this function can be individually activated for each of the 4 synthesizers. Besides the alloted VOLUME knob, each channel can be set anyware from LEFT to RIGHT with the panorama knob.

Play Modes

Now we get to the heart of the subject. As in the Oberheim 4-Voice, here too the voice-assign modes are of great musical significance. They distinguish the PERfourMER MKII concept from all other synthesizers on the present market.

The play modes in detail:

  • M1: monophonic, unison. Massive 4 VCO / 4 VCF / 4 VCA / 4 EG / 4 LFO sounds. Inspiring.
  • M2: monophonic, sequential. Each incoming MIDI note alternates between the four synthesizer channels. This brings back memories of the Korg Mono/Poly arpeggiator.
  • D1: duophonic, alternating. Synthesizer 1/2 and 3/4 are connected (two synthesizers, each with 2 VCOs, 2 LFOs, 2 VCFs. 2 VCA und 2 EG). Each incoming MIDI note alternates between the 1st and 2nd synthesizer.
  • D2: duophonic, 2-voiced. Enables simple polyphonic playing with both synthesizers playing simultaneously.
  • P1: polyphonic, 4-voiced. Extremely attractive: 4 independent voices, that means 4 independent timbres sound polyphonically. Here the PERfourMER „remembers“ the timbre (sound channel) of once-played notes.
  • P2: polyphonic, 4-voiced. But contrary to P1 the sound channels are not habitually linked to incoming MIDI notes. The PERfourMER simply plays the next „free“ sound channel.

Perfo(u)rmance – MIDI, CV/Gate, beatings at your fingertips

It took a couple of weeks for me to realize how clever the PERfourMER MKII concept really is. It’s possible to assign an individual MIDI channel to each synthesizer. Those laborious CV/Gate modifications of the past (just think of the Oberheim 4-Voice) are redundant here, since you now get these same control options via MIDI. (Which doesn’t mean that CV/Gate is useless. We’ll get back to that later.)

I’d like to take a little detour and explicitly praise the Manikin Schrittmacher sequencer. It’s a perfect partner for the PERfourMER MKII …

The PERfourMER is an unbelievable creative tool - especially in combination with a powerful MIDI step sequencer.

The PERfourMER is an unbelievable creative tool – especially in combination with a powerful MIDI step sequencer.

4 independent note- and aftertouch-tracks enable you to control each of the 4 synthesizers separately with individual patterns and filter modulations for each channel.

But the optional analog control via CV/Gate has a charm all its own. Some of the attached samples are created by using the analog trigger-sequencer TAMA TSQ1000. It has 6 triggertracks (whereby, needless to say, I could only employ 4 with the PERfourMER). These automatically set the „drum beats“ of the Vermona in motion.

Purists tend to revert to CV/Gate because of the „human feel“ (beautiful groove) native to analog sequencers.

Vermona PERfourMER and Alesis Andromeda.

A specialty of the PERfourMER MKII is that you can activate pitchbend control for each synthesizer channel individually. It’s really easy, for example, to utilize synthesizer 1 and 2 as a „potent“ lead voice, simultaneously controlling just the second synth via pitch bender. Beatings at your fingertips, that’s exactly what you get. Minimal pitchbend movements have a huge effect on the sound, it’s really ingenious.

Thus, too, with the sync-sounds. As soon as the slave synthesizer (the second one) is controlled via pitchbend, you can manually create that famous sync-effect. As with the good old Moog Prodigy.

As you can see, I got to know the PERfourMER MKII with all its inherent possibilities “slice by slice”. Every little feature promissed an immediate, useful and – musical ! – gain. And it was these little details that actually made it „love at first sight“.

I almost forgot the manual trigger button (TRIG) for the envelope (there are 4 of them). You won’t be using this much in live performance, but I sense clear advantages for every-day life in the studio. Need some proof? For a quick sound check just trigger the instrument manually. No setting up complicated connections via MIDI or CV/Gate.

By the way, the PLAY MODES are connected to the TRIG buttons. So in M1 mode, any manual trigger starts all four envelopes, whereas in P1 mode any trigger button lets the sound jump from one synthesizer channel to the next.

The rotary SELECT switch is also used for calling up the (factory and non-editable) sequences.

The rotary SELECT switch is also used for calling up the (factory and non-editable) sequences.

“Sequences”

By the way, the TRIG buttons also start the 16 internal sequences. These are pre-set. To be exact, there are 4 single tones and 12 sequences:

  • 1: VCOs in the 1. octave
  • 2: VCOs in the 2. octave
  • 3: VCOs in the 3. octave
  • 4: VCOs in the 4. octave
  • 5 to 16: 12 factory sequences, to be played as they are

We don’t want to forget the built-in tuning fork, the „A = 440 Hz test tone“ switch.

Little list of wishes (five things)

  • First, a further reduction of the (admittedly barely audible) „hot noise“. You may not even hear it.
  • Second, I’d swap the velocity and aftertouch allocations: VEL for VCF and AFT for VCA.
  • Third, automatic (voltage) control of pan.
  • Fourth, CV sockets for VCF control.
  • Fifth, the simplest of the lot: the use of coloured knobs for programming comfort. This would enhance the very clear arrangement of the front panel. Red knobs, for instance, for the VCFs (filter frequencies) and VCOs (waveforms). This could somewhat reduce the effectiveness of the already elegant colour design (anthracite – beige – brown).

The essence

The PERfourMER MKII is convincing: I like its authentic analog sound and its splendid performance. And I can especially recommend its superb hardware, its almost-perfect layout, and well, actually, the whole PERfourMER MKII. (Not exactly a catchy name, that, what with the „Mark II“ suffix and all)

Every little aspect is significant. There’s a musical solution for each problem. Contrary LFO-sweeps (via differing phase settings), independent MIDI channels for the 4 voices, analog control via CV/Gate (together with modular systems, analog step- and trigger-sequencers), etc. Practically inexhaustible sound possibilities: basses, sync- and lead-sounds, effects, all kinds of noises, drum sounds. This and more.

LFO synchronization (left side) is a very useful feature.

LFO synchronization (left side) is a very useful feature.

This instrument is a discrete-analog synth for the creative and demanding musician, especially for those who are inspired by the existence of four independent synthesizers in one casing. For those, too, who cherish attractive beating possibilities, who consider fine nuances between the single sounds to be the nature of music (whereby electronic instruments actually are a step closer to the reality of acoustic instruments). For those who have dedicated themselves to sound research.

The 45 minutes of audiofile supplements are meant to round off this review. The samples were taken almost exclusively from the PERfourMER MKII, complemented by a couple of mix-soundfiles where the Alesis Andromeda and Elkas Synthex come into play.

– the new Four-Voice?

  1. Best online review i’ve seen so far but i really dislike it when audio examples are mixed with other instruments. Please can you explain which elements from the ‘Mix Soundfiles’ are from the other instruments. Thank you!

    • … all soundfiles are listed in the Listening Room, too. There you have detailed explanations (e.g. Mix 2: Vermona drum & bass pattern triggered by TAMA’s drum sequencer TSQ1000 (> 4 gate tracks). With Andromeda lead sound). Have a look …

  2. Fantastic review !
    I’ve just read somewhere that MIDI isn’t that great and lacks when you turn legato mode off… can someone verify that ?
    And what about VCO tuning instabilities ?
    And the demo tracks are wonderful, as usual :)

    • I didn’t notice any MIDI problems, but possibly there are problems with legato mode, I’ll ask Vermona. VCOs are very stable (hm, maybe too stable for some of us?) …

      • Hello.
        Did you ask Vermona about this Legato MIDI issue?

        I very much want to get this synth but this issue will be a deal breaker.

        • We just received the answer. Here’s the translation:

          “There was actually a bug in conjunction with legato mode. This has been fixed with the penultimate batch of the PERFOURMER MKII some time ago. If there’s any problem it can always be solved by us. In the worst case this means the device needs to be sent to us.” (Vermona, 07.08.2012)

          So, the MIDI/legato problem should be erased, as Vermona says.

          Regards, Theo

  3. I own a Perfourmer Mkii CV version, this is a great review I was looking for a In depth review like this before I bought mine as had no way of trying before I bought.
    I love this synth its my favourite of all my synths, I don’t agree with your wish for other colour buttons for cut off etc I think the oatmeal look is superb and wouldn’t change it.

  4. Well written and great sound examples.. maby a couple of more with some noice osc. examples!

    • Hello Peter, you have to be a little patient. I sent the Perfourmer back to Vermona, but I’m planning to buy the instrument in Autumn. (With less noisy VCAs, that’s what Vermona is working on and that’s what I’m waiting for). Regards, Theo

      • less noisy VCAs? do you know if this changes are already present in the new ones? I´m planning to get one and of course want the less noisy one!

        • … hello Daniel! Sorry for the late answer. As far as I know the changes have been done. A friend of mine bought the Perfourmer MKII in December and there was no noise …

          Regards,
          Theo

          • yeah! I got mine now and it´s really quiet and lovely sound!
            thanks for your review, it made me decided to get a perfourmer and I really love this synth
            it´s one of the best-sounding ones I ever owned

  5. Hi. Thanks for a great review. I want to buy one but have a question. Do you know if it’s possible to trigger all of the 4 oscillators using only one of the cv/gate inputs?

    • Hi Erik. At the moment: No. All CV/Gate inputs are parallel. There’s no “master” CV/Gate to control all 4 synths with one input only. But you can solve this easily – either with multiples or with a special (1 to 4) cable.

  6. I found a very well priced one of these on the Vemia auction and could not resist. Got absolutely lost with it today (in a wonderful way) playing a simple sequence through the dark time with a touch of reverb. I’ve never known an instrument like it! Such wonderful sounds and such possibilities.

    Thanks Theo for your review and advice. This machine really is a cut above.

  7. hi, just got this piece, convinced by your review. i can’t play it with my midi keyboard controller in ableton. can you please explain me STEP BY STEP how to manage that please ? i understood how to assign midi channel to each synth but the rest is mystery…

    • I have midi keyboard that goes with USB to PC. What I do is, I create a midi track in my project, inputs I have all inputs. On outputs I select my soundcard, and then you can select a midi channel. Every synth has midi channel of 1 unless you have changed it. It is worth noting that on “In” mode you can play the synth, and on “Auto” mode the synth will pick up midi notes you have programmed or recorded in Ableton.

      Then you create an audio track, it should have ext in , and select the channel you’re getting green light. This is only if you have synth setup into your DAC’s “line in” or “microphone input”.

      Hope that clears up a little bit

    • … hello … I’ll send you an email in parallel. Just a short note: I don’t use Ableton, so I don’t know your specific situation. It sounds mysterious – a MIDI keyboard controller should work without problems, shouldn’t it? (THAT’s why I love the CV/Gate option …! I really don’t like MIDI too much).

      Anyway, “online browser” answered, too … so I hope you’re able to manage the keyboard problem …

    • … VCF modulation is realized via external sequencer and MIDI aftertouch messages. No (analog) Filter-CV-in, sadly …!

  8. so the filter resonance examples seem to not include any significant volume drop, yet mine is quite significant(on all channels). i just wanted to know if you used any external gear to boost the volume level with increased resonance of the filter cutoff freq. ive contacted vermona and they have said that this volume drop is normal but it seems to be quite extreme with mine. especially noticeable when compared to youre audio examples which is why im asking of the process of producing them. thanks!

    • … hi Frank! No, I never use external gear for volume compensation. The Lexicon MPX-100 adds some delay effect, that’s all. Other than that all soundfiles are pure plug & play & record.

      Volume drops at higher filter resonance settings, correct. IF it seems to be extreme in your case (making your PERfourMER MKII useless in some musical aspects), you might send it back to Vermona and ask them for a technical check. Or you might try another PERfourMER MKII (does IVE own one?) and compare both units, just to figure out whether your volume drops are standard or not …

  9. Hello.

    If you had to choose only one synth… Dominion 1 or Perfourmer ?
    Which would you choose:) ?

    • Piuhhh, that’s a difficult question …

      Regarding powerful sounds and “pure” analog cleanness, I’d go for the Perfourmer MKII (which is just a classic analog machine with no compromises!).

      Regarding versatility and performance, combined with a strong and yet flexible sound architecture, I’d choose the Dominion 1.

      Best to have both … :o)

      [ok, ok … if you wish a non-diplomatic answer: I’d go for the Perfourmer MKII. Finally, it’s the pure SOUND that matters].

      • I agree this is hard to answer. Honestly, both the Perf mkII and the Dominion 1 are synths I would choose over current model Moog, DSI, or Korg analog synths. They both fill their respective gaps nicely and for less many than Moog or DSI.

        For me it’s a no brainer to own both Perf mkII and Dominion (if they can ever stock Dom1 in the US) but the real debate for me is DRM1 mkIII or Tanzbar? :)

        • You think the PerFOURmer fills a gap cheaper then DSI? What has been stopping me from getting it yet is that for only a bit more money I could get a Prophet 8 or used Polyevolver, which seem to have a LOT more capabilities, more total oscillators, more modulation, plus a keyboard, for what thats worth. For analogy sound, this is cream of the cream…what do the French call it? Oh well, I dont know, but its pretty damn creamy. Do wish it had drive on the filter.

  10. Hello. In full poly mode, is it possible to have 1 filter cutoff control all filter cutoff’s?

    • Hi Alex … sorry, that’s not possible. No “General VCF Tune” knob as on the Oberheim Four-Voice, sadly. I would be happy if Vermona would release a slightly modified Perfourmer MKIII … with 4x VCF CV IN (one for each synth section) and a global VCF CV IN jack … that would be perfect … cheers …

      • Oh what a shame.
        Wouldn’t it be lovely to filter sweep all 4 oscillators at once. I bought the unit without the CV/Gate.

        I was thinking… Retroverb Lancet.
        Feed Perfourmer headphone jack into retroverb and have the added bonus of HP, LP and BP as well as LFO modulations and glorious spring reverb.
        I wish it was stereo though:(

        Thanks Theo.
        I always love reading your reviews:)

      • Just regarding this issue. Does it effect your enjoyment or workflow with the synth? It seems like a strange omission as a global filter cutoff would complete it (as well with BPF HPF).

        I’m just weighing up this one as it sounds really great. I cant help but feel not having an overall filter would annoy me.

        • Hello Joe … well, there “is” a possibility for global filter control – via aftertouch (which does not replace the hardware knob we’d wish for, I know). I think you’d be happy with the Perfourmer MKII. It’s sound is just amazing, and the 4-synths-in-one concept is unique. Enough sound potential and creative possibilities to make excellent electronic textures for many (many) years …

  11. Excellent Review man, thanks for that, you convinced me to give it a try & i’ll definitely have a look on this website for every single instrument i would like to buy !

  12. I’d like to thank you for this excellent and thorough review. This was the push over the edge to buy one a while ago.

    I have this baby for nearly a year now and it’s my favourite synth by far. The possibilities are broad, the build quality is top-notch, and it’s a super fun synth to play with. I use it in my live rig for my band, couldn’t have chosen a better synth for the job. Thanks again!

  13. Hey great review. I have two questions.

    First in regards to the independent vco outs. Am I correct in assuming that if you run cable from those into a modular unit all of the other controls are no longer usable? That basically the perfourmer becomes a sound source? You don’t get to have those oscillators feeding separately into your modular and also use
    Them within the perfourmer itself.

    Second question is it possible to daisy chain two of these together and get an 8 voice? Or chain anything else to it to expand polyphony?

    Thanks

      • I`m interested too. I have MKII, but want to know, is it possible chain two Perfourmers for 8 voice or 4 (duo mode) voice.

  14. … spoke to Vermona. Stacking 2 Perfourmers (to get an 8-voice machine) is “not” possible. Sadly …

  15. @steven, vco outs are available simultaneously with stereo outs as well as voice outs. patching a voice out willl break connection from stereo outs but with some clever patching (out can be used as insert) you can achieve quite a few outputs simultaneously. its fun figuring this thing out.
    @theo and rest:
    however i have a question, ive had my p4mer for about two years and ive noticed the panpots emit noise when turning as well as master volume knob. even worse, when oscillator is in lo mode sweeping the resonance knob makes noise as well. anybody encounter this?

  16. Thanks for this nice review. I’m thinking of buying one, however I have a question. Can I assign midi channel 1 in Cubase to VCO 1, midi channel 2 tot VCO 2 etc, and make it kinda 4 voices poly like that?

  17. hello, i love the sound of the mkII and dream to buy one in december. I’ve been told i was stupid because it would bring me problems instead of solutions as my current set would not cover enough ground (got a minibrute & grenadier & grendel drone commander as main/definite keeper synths so not really the synthesis basics like multiple oscs, hardsync, S&H, FM etc…) and i own the fabulous drm1 mkIII for a month. I think it would be a hell of a set with the P4M but the friend says i should buy an ArpOdysseyRev3 or minilogue instead for half the price with a lot more options, ground covering etc…that the P4M is elitist, luxury synth. According to the vids, i’m heavily more attracted by the P4M soundwise. i don’t care much about having all tricks or possibilities. i think it would complete and end my 100%hard set. Am i indeed stupid? to be only relying on my ears ? notwithstanding the technical palette? is it a synth for confirmed synthesists? I have a vague idea of the answer, but would like to hear advice from people who know the monster synth well please.

    • Hi Daniel … well, say “hello” to your friends … comparing a Korg/ARP Odyssey or MiniLogue with a PERfourMER MKII is nothing than a joke (well, maybe they were joking, I don’t know). Anyway, I guess you want a true instrument (not a toy) with professional hardware and a professional sound? Trust your ears and go for the Vermona, really. You won’t regret it …

  18. thanx, just read your comment. Have bought the P4M at Xmas and don’t regret it ! It’s awesome ! Huge ! Love it! This was made for me. Glad i followed my little voice.

  19. To look at a synth’s features is ridiculous. Number of VCO? Any of the P4M’s single VCOs sounds better than two of them on mainstream synths. One cannot compare by features. Only by ear. And the Vermona sounds really killer !!! Then what it does, combining the monosynths ! It’s evil…impossible not to create a song each time you feed it with a few notes !!!!! Definitely my main synth and keeper !

  20. I also bought a perFOURmer, and it will be here in a few weeks.

    Here is my tentative mono set-up
    Timbre Wolf (sounds off) MIDI out controller
    controls p4M, MIDI THRU to MS-20Kit keyboard
    CV/trig out to stereo monotribes (Hz/V-S-trigger)

  21. Just got a perFOURmer in May 2017.
    Plays very well to add the bass back in that is lost when running an
    MS-20Kit in Bandpass mode. Also plays well with triangle on my two Monotribes!

  22. Hi,good site/review.Lovely sounds from this synth! very interested in one but i wonder if the midi spec covers enough?,can’t find the info anywhere,can anyone give details please? i thought id ask here before e-mailing Vermona.cheers

    • I mean do all pots send/recieve midi cc msg’s.can anyone confirm?.Vermona e-mailed the manual but no explanations.cheers

      • … hello Gs

        The Vermona Perfourmer MKII is a “pure” analog synth. The pots do not send / receive MIDI CC … There are basic MIDI functions, though, … Velocity, MIDI clock, etc. – but that’s it. What you get is the (neart-to-)perfect analog SOUND :o)
