OK take two! I have multiple controllers I want to record independently on different channels in Logic 8. A PadKontrol and Edirol Keyboard which are both USB devices. I need a way to separate each controller so I can record different AU Plug-Ins on each controller.
In the environment the Edirol shows up along with the Cap Lock Keyboard but no Padkontrol. I've created an additional instrument in the environment and the Padkontrol is a pulldown option. Even if I assign each device to separate midi channels and play only one, both sounds are played together regardless of the controller I play. Anybody have a fix or a work around?

Thanks in advance,

Yes.

In normal operation, Logic listens to all incoming MIDI ports, and sums the data together, forwards it to the arrange page, and then distributes it to the selected instrument track - hence all controllers which be channelised to control the current instrument (or multiple instruments).

If you enable "Multiplayer Record" mode, then what happens is that Logic distributes incoming MIDI events to the selected tracks via the MIDI channel.

So, you can set track 1 to listen to channel 2, track 2 with a different plugin to channel 14 etc - up to 16 channels.

So in this way, you can play up to 16 independent instruments from up to 16 independent controllers.

Logic currently has a bottleneck at the summing point, which means you lose the incoming MIDI port info, which is why your controllers need to be sending on different MIDI channels, but in short, set controller 1 to transmit on one channel, set controller two to transmit on a different MIDI channel, have multiplayer record enabled "Auto demix by channel if
multitrack recording"), and you can then choose which track should respond to which controller by adjusting the track object's MIDI channel.

The manual explains the procedure in "Recording on Multiple MIDI Tracks" on page 382.

Thanks for all your help!
