How do you change the midi channels of a region?

Question

Lets say i have a region recorded on midi channel 1, how do I change the notes to be midi channel 2? Thanks

Answer 1

Depends.
First of all, are you talking about a MIDI region or an Audio region (Audio regions can "be on a MIDI channel", so to speak, if they contain controllers, i.e., volume, pan, etc.).
So let's say you're talking about MIDI regions for now.
The first order of business is to recognize that the actual channel of the MIDI events contained in the region is determined primarily by the MIDI channel that your controller is sending on. For simplicity sake, let's say your controller sends on channel 1, and the track you're recording on is set to play MySynth on channel 1.
If you're wanting to change the channel from 1 to 2, chances are you want to do this to assign this part to play a different sound on a multi-timbral synth. Let's say that the MySynth object -- as seen in the Environment -- is indeed a multi-timbral synth. If the synth selected for that track is currently assigned to play MySynth 1 (i.e., channel 1), just change it to MySynth 2 (from the track's menu).
Now, if you opened the Event Editor, you'd see that the channel of the MIDI data is still on channel 1! This is normal. Logic is able to "channelize" the data when you select a destination instrument that is on a different MIDI channel from the one that the data was recorded on. So if your track is now set to play MySynth 2, you can go into the Event Editor all day and change the MIDI channel of the data, but it will still be channelized to channel 2 because that track is assigned to play MySynth on channel 2.
There are many many reasons why you might still want to change the MIDI channel of the data in the Event Editor despite the channelizing that goes on. But without going into a whole shpiel about these kinds of applications, just know that the primary way to change the MIDI channel is to select an instrument on the desired MIDI channel.
