Hi,

Does anyone know how I'd intercept the APC40 MIDI so I can start to make changes to it.

I've tried using a virtual MIDI cable, feeding the MIDI into PD, then into the cable: and recieving MIDI back from the cable and sending it to the APC40, but:

1: This causes a weird feedback issue: when I turn a knob Ableton gets updated and immediately sends a MIDI response, which PD sends back to the APC40. This causes slow knob response and flickering: it looks like the APC40 is getting confused by the returning MIDI signals.

The same thing does not happen when the APC40 and Ableton are connected together directly: even though there is two-way MIDI. Obviously the issue is solved somehow: but I don't know how to do it.

2: A lot of the APC functions simply doesn't work: although I've simply done midiin --> midiout with all the available MIDI interfaces. The handshake between the APC and Ableton supposedly goes through MIDI, and other people have got it working with Bome's MIDI Translator: so it's definitely possible. Any ideas on how to get it working?

Cheers,

Will.

Woops!

I think I solved issue one: I was sending and receiving via the same virtual MIDI cable: so the APC40 was sending a MIDI value, then PD was promptly sending it back.

I've got separate In and Out MIDI cables now, and it works fine.

However, I still can't get Ableton to do the handshake.

same same...
ableton is receiving the notes as pd. but so far no LED´s in the scene...
