The iVCS3 is specifically designed for the iVCS3 iOS app. It features an iPad slot to hold your tablet. The upper front panel has additional knobs and switches for the step sequencer and the flanger.
The custom design is built around the Doepfer MIDI USB64 interface. The 2-octave keyboard is a Fatar keyboard.
Synth Project designs are created by M. Jurisch, who builds custom controllers because they offer the tactile feeling of old school synthesizers. His custom controllers are created as a hobby – not as a business.
