The detuned 921B VCOs give a fat sound, whose timbre changes constantly at the speed of the 921sine wave – the 921 should be in Sub mode, speed can  

be adjusted to suit.
The main part of the sound comes from the 904A LPF, whose Fixed Control Voltage and Regeneration can be set to whatever suits your aim.  The second part of the 

sound is a bandpass effect from the 923 Filters.
911 EG settings can be adjusted to suit for the main  part of the sound, although medium to high levels on T2 (decay), T3 (release) and E sus(tain) are recommended.  

The second part of the sound should have a short T2 (decay) and minimal T3 (release) and E sus(tain).
The second part of the sound should be lower in the final mix

Percussive Lead

A simple, two oscillator lead sound with a hard front end and timbral development which is also suitable for melodic sequencing
