Hallo, f.bardet@voila.fr hat gesagt: // f.bardet@voila.fr wrote:

I need to control from PD the transposition of an audio input to a digital effect processor (ref. LEM FX24). This machine can do it through a knob, and can also receive MIDI messages. I guess I can control this from PD sending MIDI messages with the block “ctlout”, but I didn’t find a MIDI controller number for transposition. (as controller number 7 is for main volume). Any suggestion or MIDI documentation to help me ? Thanks for your advices.

You need to check the manual of your device. Even though there are some conventions like Ctl 7 for Volume, there's not guarantee, that a midi hardware or software follows this convention. Take Pd: You can do everything with Ctl7.

Your effect processor might even use note values for transposition. So check the manual.

Ciao
