Hope this helps, it works for me:
The “Oscillator Modulation” switch modulates oscillators 1,2 and 3 via oscillator
3 with an amplitude that is dependant on the modulation wheel. If we don’t want
to have oscillator 3 modulate itself, we need to deactivate the switch.
The cables on the left:
The “Glide” switch: activates or deactivates the glide. It can be controlled by a foot
switch pedal. In this case you must click on the jack on the left.
The same is true for the “Decay” switch activating the time for the return to zero of the
envelopes.
