… a Sequential Pro-One? You might come to this conclusion when listening to the attached video. (Possibly) surprising result: Soundwise, there is very little difference between the two instruments.
However, it is important to notice that the sounds in the video are (more or less) basic analog sounds. Basses, filter sweeps, leads – that’s it. And that’s why the Pro-One <> AS-1 comparison falls a little short. No weird FX-noises, no elaborate modulation-sounds, yet rather plain bread- and butter-sounds. Sounds that can be produced rapidly and compared easily.
