I am using Logic Pro 9 in a live setting and have set each track (software instrument) to a different MIDI channel.

Unfortunately the only track that plays is the one that is highlighted.

 

Is there a setting that will stop this behavior?  I want to be able to cycle thru the MIDI channels and have each one play a different sound.

 

Thanks for any suggestions


Logic Pro, Mac OS X (10.6.8), Axiom 49/Roland Stage Piano

    If i understand what you are trying to achieve correctly (and if not, please add some more info)

     

    Logic only plays the track that is record armed.. (When you select a track it automatically record arms that track...

     

    So... record arm all the tracks... (Option left click on the r butttons in the track headers)  and then change midi channels on your keyboard... remembering to change/setup the Midi channel in the Instrument inspector from all to the channel you wish to assign to each track... for each track.

     

    You should now be able to achieve what you seek to do...

     

    As an aside, for anyone interested in layering Software Instruments (SI's).. in real time... Leaving the Midi channel setting in the Instrument Inspector set to all... and option clicking and arming all the tracks.. allows you to play/record several SI's at the same time... bearing in mind any controller movements will affect all tracks at the same time too!

    A simple "Click" on each track's Record button should suffice (no Option necessary).

     

    If the OP wishes to be able to play different tracks/channels (instruments) simply by changing MIDI transmission channel on the controller, it will not be enough to arm all the tracks and assign each track to a different MIDI channel in the Track Inspector. They will most likely all play, regardless of MIDI transmission channel.

     

    Go to Settings:Recording and check "Auto-Demix by Channel if multitrack recording". This should do what you need.

    Hi Art:

     

    Thanks for your email. 

     

    I believe you have a good understanding of what I want to do.  I armed each track for record and double checked they were all set to different MIDI channels.

     

    Unfortunately the only track to sound is the one that is highlighted in the Arrange window.

     

    If you have any other suggestions - I'm all ears.

    Read CCT much more accurate version of what i was trying to describe when I was away from my Mac

     

    I had completely forgotten about setting Auto Demux.....

     

    (Thanks CCT as always!)

    Just received your email on setting 'Auto-demix by channel if Multi-track recording'.  I checked and set that.  Does the setting in Overlapping recordings matter?  I have it set to 'Merge Only in Cycle Mode'

     

    At this point - the MIDI channel makes no difference and the only sound is from the highlighted track.

    Should not matter.

    So:

    You have a few Software instrument tracks (with Instrument plugs). You arm the Record button on all the tracks by clicking on each one. Do they all light up?

     

    Regardless of incoming MIDI channel, they should ALL play if you have not checked "demix" in the Settings:Recording box.

     

    If you are only getting one playing (the one that is selected) there is something else wrong.

     

    Maybe you could post a screengrab (including the Track Inspector).

    Remember that Auto-Demix is a "Setting" it's enabled on a per project basis, it's not a global setting that sticks. Each project will need it enabled.

    I just wanted to thank everybody who responded to my post.  I had been using the step input kb but when I got back to the studio and tried it on an actual MIDI kb - it worked.
