Fig. 3: Four-step tone sequencing
P
If you use a keyboard gate as the trigger
instead of the LFO, each note played steps
through to the next envelope.
Switching filter characteristics
With the patch in Fig. 4, you can use an A-151 to step
through each of the types of output in the A-121
multimode filter, one step for each note played.
