Synthtech E370, 4 voices controlled by a Roli Rise using MPE

"This video demonstrates the Synthesis Technology E370 Quad Morphing VCO, played as a 4-voice synthesizer using MPE controlled by a Roli Rise 49. This was recorded live, no filtering of the E370, with a phaser, convolution reverb and delay in post processing. The only sound generator is the E370.

The 4 voices of the 370 are identical, in 4-voice cloud + morph mode. The MIDI signals from the Rise are converted into control voltages using an Encore Expressionist (8 CVs + 4 gates) and the CV Toolkit software (6 CVs) for a total of 14 CVs and 4 gates.

Each of the 4 voices has 3 independent CVs controlling pitch, volume from MIDI velocity, and cloud spread from the Roli Rise glide (finger position from the front and back). One additional CV controlling overall volume is controlled by an expression pedal, and the last CV from a slider on the Rise controls the morph waveform, which is the same for all 4 voices. In addition the waveform is morphed around the value set by the slider by a slow LFO triangle wave. The note dynamics are controlled by 4 ADSR envelopes triggered by the 4 gates."
