I recently got an A-152 and am using it to select the columns of two of my PGM-4X4 programmers to make sequences that can have programmable patterns to them. What I would like is to mod the A-152 so that I can add an output that produces a trigger whenever the A-152 addresses a new step. This way something like a sine wave into the A-152 would make the PGM-4X4 work like a pendulum and would also produce triggers to fire off envelope generators whenever a new address/column/note happened. Is there some internal circuit logic that can be added to create a trigger out like this

Any ideas would be helpful.

Actually this would be a good idea for a new module. A module with an input CV jack with level control, and an output jack that would produce a trigger (or a width adjustable gate) whenever the input CV changed voltage by and adjustable threshold (knob or external CV control). It would be even nicer if there was a way to either have separate trigger out jacks for producing triggers for positive voltage changes or negative ones.

In any case if anyone has an idea of how to accomplish this with different modules or if there is a way to mod the A-152 to produce triggers, let me know. All I can think of now is to take all of the digital out jacks, make a gate to trigger converter for each one (since they are high for their whole duration) and OR them together for the combined trigger out.
