System 55 Patches
Expressive Lead #1
To mixer/ampli er/DAW
This patch is a full-on three oscillator lead synth soloing creation, with a delayed vibrato effect that fades in when a note is held.

The external keyboard controls the pitch and triggering of notes via the CM1A MIDI Interface. As this can be switched between v-trigger and s-trigger then s-trigger
should be selected and the 961 Interface need not be used.
Pitch CV is fed to one of the 921As, which daisy chain to the 921B VCOs. Pulse Width Modulation is also daisy chained. The selected waveform from each oscillator is
fed to one of the CP3A-M mixers; which then feeds the 904A LPF. S-triggers are fed to a multiple, and then to two of the 911 EGs' s-trigger inputs and the s-trigger
input on the 911A
The output of the 904A is fed to one of the 902 VCAs, which feeds out to your mixer, amplifier or DAW. This VCA is controlled by the first 911 EG. The second 911 EG
feeds the 904A control input. The 911A feeds the third 911 EG, which controls the second 902 VCA.
The second 902 VCA signal input is fed from the 921 LFO. Its output is fed to the fourth input of the C3PA-O, so that it can be attenuated if necessary. The C3PA-Os
three outputs feed the DC Modulation inputs of the 921 VCOs
The third 911 EG should have a long attack time and full sustain. The 911A should have a delay of two seconds or more.
So long as the first 911 EG has a long sustain time, when a note is held a vibrato effect will fade in after a delay (Time set by the 911A). When notes are played legato
there is no vibrato

This patch creates two of the classic 'space rock' sounds, and allows them to be mixed together.
