I sent this to [email protected], so far without reply.

It seems that when Live passes MIDI note on messages through to AU
plug-ins, the MIDI channel of the message is always '0', even if the
MIDI message was sent on another MIDI channel.

Is this intentional? It presents serious difficulties to plug-ins such
as mine that rely on channel information to address different
functions.

I tested Live 4.1.4 and 5.2 on OS X, both of which behave this way.

Would be interested to hear others' thoughts on this.

cheers,
os.

Hi os,

Yes, its intentionally.

We decided to keep the MIDI channel issue as simple as possible for the user, so Live will always send MIDI to any kind of plug-in (VST/AU) via MIDI channel 1(0).

best regards

Hi,

thanks for the reply.

I personally feel that that's a mistake, and is unnecessarily limiting the user - but then I would, since it's causing a problem with my plug-in. I'm surprised this isn't a more widespread issue for people.

Anyway, at least I now know for sure what's going on.

cheers,
os.
