Switching patches with midi program change

#1

Hello all, and a big thanks to everyone that are contributing to Axoloti. I've been using it for simple synth sounds for a while, but it wasn't until yesterday I finally got around to exploring the board properly. I'm having tons of fun, but ran into a newbie issue I haven't been able to solve yet.

I want to be able to switch patches using program change messages from my controller. It works with CCs, like this:

But when I try to use the pgm object shown in the image instead, it does not. Is there any way to monitor what is output from the pgm? I assume it is not the program change value since it isn't behaving, so what is pgm outputting?

The easiest way to debug your patches is to use the objects in the disp folder. The disp/i object in the screenshot shows the output from the midi/in/pgm object. Note that the clip in Ableton live is set to program 4, and is displayed as 3 in the Axoloti patcher.

Ah, perfect. Exactly what I was looking for, thanks!

I just tried it, and I did in fact get the program change value as an integer. So I reconnected the pgm object again, and now it works!. So whatever was giving me an error before appears to have been fixed by itself. :smile:
