James, Synthetic Sound Lab's V-Gates will do this. In its Analog mode, cv input can be swept in different ways to its 8 outputs as triggers. It also produces a single trigger out each time that threshold of each trigger level is passed. It's a very complex module, and is capable of doing much more even.

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?

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.

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.
