This sound uses two 921B VCOs, with different waveforms, and sounds best if one is slightly detuned. They both feed the 904A LPF, and their relative levels can be
adjusted with the CP3A-M mixer as required. The 904A's output is fed to a 902 VCA, whose amplitude is controlled by the 1st 911 EG
To obtain the percussive edge the 911's settings should be T1 (attack) 2ms, T2 (decay) 200ms, T3 (release) 200ms, E sus(tain) 4 seconds
The 904A is modulated by a slow sine wave from the 921 LFO and by the 2nd 911 EG, which should have settings around T1 (attack) 1 second, T2 (decay) 50ms,
T3 (release) 4 seconds, E sus(tain) 9
