Ableton Forum

When using a mouse, Ableton only allows you to arm one midi track at a time. I want the same action with a mapped button. When I map the arm buttons to different controller buttons, and trigger them, they all stay lit until go back and turn them off. Any ideas?

Thank you!

under the preference menu, record/warp/launch. Turn both OFF under exclusive: arm, solo

Right on the money !!

Auron, thanks for the response. Unfortunately it still allows multiple instances of arming when I unselect the arm and solo options in the prefs.

My scenario is that I have Reason instruments rewired on different Ableton midi tracks. I would like to be able to arm only one midi track at a time so I don't end up playing multiple instruments with the same key. Currently when I want to switch instruments I am playing, I have to remember which track I have armed, go back and un-arm it then select the new track to arm. It would be much easier if I was restricted to only arming one track as happens when using a mouse. I also tried mapping a different controller with the same results. Any other ideas are greatly appreciated.

Thanks!

J,

actually my mistake, the instructions I posted were for altering the default Ableton behavior of arming only one track at a time. but it should have gotten you to the right place in preferences.

if you have exclusive: arm activated then when you click the controller's button for arming the track the other ones should automatically be disabled by ableton. check your preferences again!

I have an MPD32 and I just checked to see if it would work...when I click the button mapped to arming track 1 then other tracks are disarmed just like when you use the mouse.

For my own setup I turned off the exclusive behavior off because I manually arm the tracks myself and the track's button (set as a latch) lights up letting me know its armed. So when I am playing I can always look at the controller to make sure the right tracks are on/off.

but that's my setup, I suspect you had a project with the default preferences for arming tracks changed (exclusive: arm was off) and that's why it wasn't working.

Exclusive arm w/ a mapped MIDI control does not work as designed. If manually mapped you can still arm multiple tracks. I've run into the same problem, it's a bug.

Thanks for the responses. It looks like you are both right. I still cannot set it to select only one track and it seems like a bug as Ace mentioned. If anyone has any clever workarounds that would be great, otherwise I guess I will have to un-sarm each track before playing a different one.
