Problem with MIDI overlap

Problem with MIDI overlap

I'm having trouble with MIDI info from my M-Audio Trigger Finger and Edirol keyboard MIDI controllers overlapping. I have set each up in the environment to have only one channel activated (channel 5 for the Edirol keyboard and channel 12 for the TF). In the arrange view I have separate tracks with an Ultrabeat track on channel 12 and an ES2 track set to MIDI channel 5. But when I play either device when both tracks are armed, BOTH MIDI controllers play through both tracks. What have I done incorrectly? Thanks very much for any help.

Please be more specific about what settings you have made so we can set you straight.
You probably activated just those channels in the Multi Instruments. All that does is make it so you can only create tracks for those channels in the Arrange window.

Anyway, that doesn't answer your question.

To do what you want, you need to use 'multiplayer' mode.
This is described on page 122 of the Logic Pro 7 Reference manual.

I have set the Trigger Finger to channel 12 via its program mode and the Edirol to channel 5. I would like the TF to trigger track 1 (input Ultrabeat) and I have set the MIDI channel to 12 in the parameter box. I've also set up a track 2 (input ES2) and have set the MIDI channel to 5 in the parameter box.

When I arm both tracks to be played and recorded by two musicians at the same time, both the TF and the Edirol trigger sounds from both Ultrabeat and ES2. Even after reading the Multiplayer Recording section again I don't see an error in my setup. Please advise on how to fix this- I'm very grateful for the help.

Did you follow this part;

To switch from the Layer recording mode (default) to the Multiplayer recording mode, select the File > Song Settings > Recording > Auto Demix by Channel if Multitrack Recording option.

Setting that option in song settings channelizes the input to specific channels.

If you have that set up, make sure both tracks are armed and
select the lowest channel (track 2) in the tracklist.
it should work now, but if it doesn't, moving those tracks to the top of the tracklist should help.

It seems that it becomes problematic with 3 devices. It can work but only if the most recently assigned track is highlighted. Otherwise 2 out of 3 of the controllers wind up with the same MIDI instrument and patch (even when all else is configured correctly). It works well with 2 controllers. Thanks again.

if you have any trouble with going directly to the AudioInstrument tracks, you can do this:
Create a Multi Instrument and a Channel Splitter.
Cable the Multi to the channel splitter and then cable individual channels from the splitter to your AudioInstrument objects. (set the MIDI cha on the AudioInstruments to 'all', just to be safe)
Drag the Multi on to the Arrange window tracklist to create tracks for it's subchannels.
Rec-enable the tracks which are assigned to the channels you are using, plus channel 1 .
Select the track for Cha 1 and play/record.

I've followed the instructions as follows:
Created a multi-instrument
Created a channel splitter and cabled the multi to it
Cabled 2 different subchannels from the splitter to separate Audioinst tracks in the audio layer of the environment, each corresponding to a track with a separate MIDI input
Dragged the multi to the Arrange window, creating new tracks
Rec enabled only the subchannel tracks corresponding to the MIDI inputs and subchannel 1; the original Audioinst tracks are not enabled
Selected the track with subchannel 1 keeping the other 2 MIDI subchannel tracks rec-enabled

When I play the MIDI controllers, only one of two is heard. The second can only be heard by selecting ITS rec-enabled sub channel track. It's workable, but no different than your first suggestion (without creating the channel splitter). The second MIDI input track has to be selected to be heard with its own input synth.

Is the sequencer running ?

Yes it is. To clarify I'm using three MIDI inputs, two keyboard and a TF. When I set it up either with or without the channel splitter the second keyboard plays through the TF or other synth input UNLESS it's selected. If I select the second keyboard all is well. If I use the channel splitter, enable, and choose channel 1 as you suggested, the second keyboard replicates the first. They are on separate MIDI channels. This happens whether the Audioinst is set up for the corresponding MIDI channel OR All.

By the way I truly appreciate your help.
