Logic Pro 9 Stopping playback in Logic 9 automatically?


Does anyone know how to auto stop my backing tracks in Logic 9?

I currently use Logic on stage to run my backing tracks. I use markers to locate tracks. However, when the end of the song comes it keeps playing. Is there a way to auto stop from markers? Or indeed ANY way to auto stop in Logic 9?

You could maybe set your song length to suit?

But instead of that I'd recommend using Mainstage, which comes with L9.
It has plugins for playback that aren't available to Logic.



A massive thanks to you! That works. You have just released me back into the guitar world when I'm live on stage.
Now... I don't suppose you would know a way of automatically changing my preset patches in Guitar Rig4 would you?
I am running my tracks in Logic whilst simultaniously running Guitar Rig as an insert effects on another audio track.
My problem on stage is while running tracks I'm running round the bar performing. So I need to be able get Logic 9 to do it for me.
I have tried automation settings but that just gives me automated control over individual effect parameters within the preset. What I need is a total overall preset change.
Can you help?


Check out the "performance" functions in the channel strip settings. They allow you to recall preset channel strips by means of program changes. So, save your channel strips as you like them, assign a program change to them via the "performance" function, and then you should be able to call them up means of sending program change messages.


Thanks Eli.
I have saved channel strip settings for my Guitar Rig Patches but how do I assign the 'performance to a program change? I have tried assigning from the Hyper Editor & the List window but no changes have happened in Guitar Rig.
Sorry to be such a dunce. I know next to nothing about midi.


Unfortunately with the channel strip performance function, you need to send the program change from outside of Logic. It won't respond to sequenced program changes contained inside regions.

There is a way though to do this sort of thing using IAC. You create an IAC bus in the Audio MIDI setup, program up a region with a program change on a track that is going out to that IAC bus. Then bring that IAC bus signal in at the Physical Input in your clicks and ports Environment layer. It's a way of tricking Logic into receiving an "external" program change. I've never actually done this myself; but it should work.


A Big thanks to all who have helped me in my stupidity.
CCT cured the problem (BIG thanks)
TO those who have steered me to 'MainStage'....As a guitarist (tho not purist) the tones generated by 'Mainstage are good but Guitar Rig wins hands down on tone/versatility/creativity etc etc.
All I need to be able to do now is change my Guitar Rig presets automatically within Logic.
For recording, main stage has EXTREMELY good tone but, live, the processing power it will take to generate what I need will max out the CPU (I even have 6 Gig Ram running on a MacBook Pro). In Guitar Rig I can get exactly what I need with plenty of CPU useage to spare.
God, I need an idiots Guide to midi.
Anyone have a PDF version?

I don't understand your take on Guitar Rig. If it runs inside Logic it will run inside MainStage and should use the same CPU. I'm not saying MainStage will suffice for your needs, just trying to say you can use any AU plug-ins in MainStage as you do in Logic. In fact, you can use the same channel strip settings that you have in Logic in MainStage, and vice versa.


Thanks Doug,
I shall certainly try out your idea (any idea is a good idea at the moment).
Thank you for your patience.

Just to add to what Doug already said, Logic and Mainstage both have the same channel strips, and also the same internal plug-ins. So the "mainstage" tone you're talking about are the built-in plug-ins named Amp Designer and Pedalboard, and those are the same in both Logic and Mainstage.
