How to access audio instruments as midi channels from midi keyboard?

Hi!

This is my first post here.
I use mostly Logic Pro 7 as a sound module with my keyboard. I have a song file in Logic that I made some time ago, where I've linked every audio instrument to a corresponding audio channel (same midi channel). All channels are in record mode, and thus every audio instrument is assigned a midi channel - and I can play different audio instruments by changing the midi channel on my midi keyboard.

Now, I want to create more tracks, so I can have more instruments to choose between. That doesn't work.. I try to make a new logic file and do the same thing with more channels, but I can't remeber how I made this work in the first place. I've been trying for hours and hours, and I'm going nuts here.
I would extremely grateful if anyone could tell me how this is done.
(No rewire/extra software is necessary.)

Thanks for reading. 🙂

Welcome!

It's fairly straightforward. On each audio instrument, assign a MIDI channel in the parameter box - so eg Audio Instrument 1 is set to MIDI channel 1, Audio Instrument 2 is set to channel 2 etc.

The key part is in your song settings "File -> Song Settings -> Recording" to make sure "Auto demix by even channel" is ticked.

Now, shift-click on the record buttons for all your audio instruments, and when you send on MIDI channel 1, you'll play the first one, switching to channel 2 you'll play the second one, and so on.

The max you can do is 16 channels at once, afaik, as the sequencer input doesn't retain port info (which is a bit of a shortcoming in my book, but there you go...)
