Hello,
I'm trying to make a patch that I can put between my FCB1010 and my guitar pedals (Eventide Timefactor and Line6 M5). I want to add a little extra functionality in between (perhaps using a raspberry pi, not sure yet)

Anyway one of the first things I want to be able to do is cycle incrementally through presets quickly, there's 100 on the TF and 24 on the M5, too many for the FCB1010 to store individually.

So in the patch I want to read the current program change message for each channel (1&2 for Timefactor and M5).

Then if either channel receives a cc message 127 (of any value, something the FCB1010 can do) I want the patch to then add 1 to the current program change value in the patch and send out a new program change message. The same will be done to cycle down the presets using cc126, and subtracting 1. I chose high values because they won't be used.

I'm having trouble automating this. Does it involve bangs and spigots? How do I +1?

I've attached what I've done so far, very basic. The left hand side is for MIDI thru and some expression automation I want to do later. Thanks

As usual a lightning fast solution using methods I would never had thought of. I will test but it looks good. Thanks.

It just occurred to me that PD wouldn't get any new program change info when this happened, so would I have to send the incremented PC number back up to the top to overwrite the current one (until a 'normal' program change overwrote it)?

for me, the hardest part is to understand your problem (I'm not a native English speaker.)
Can you describe your goal in simple words?

I have two devices and a foot controller. I want to be able to press a button on the foot controller to increment a patch (program) on each device, either up or down. For example the Timefactor has 100 presets but no way to cycle through them quickly.

ok, one more suggestion.
