921 Sine Wave Out 904A Control Input

2nd 911 Output 904A Control Input

This sound uses two 921B VCOs, with dierent 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
