MIDI Logic x Help!!

Hi, Try this....

Go to Logic's Settings/Recording select Auto DeMix by channel if Multitrack recording. Logic by default sums all Input channels and does not give each MIDI channel strip it's part of the original design and seems a bit kludgy by modern standards, as in the past 20 years!

Also, all tracks you wish to play have to be Record Enabled, and you should be using a stock environment, if you've wired stuff up trying to make it work start with a fresh project. Also... Settings are not Global, they are per project. Preferences Are global

From your video it seemed like you had possibly altered the Environment trying to get it working, you were going to show something in the environment then said never mind. While it's easy in Ableton, Cubase, Reaper..etc. Logic's Environment makes setting individual MIDI ports & channels per channel strip a chore, in fact it's a work-around that was added later. Auto-Demix, did not originally allow incoming MIDI to be re-channelized.

For it to work the way you want you will need the Auto-Demix setting enabled as well has having all tracks you wish to play Record Enabled (Live Mode), then when you switch channels on your controller you will hear the individual sounds.
