Anyone using more 2 or more controllers in Live?

[konig16]

I have a oxygen25 Keyboard and Trigger finger both made by M-audio and I can not get them to work at the same time in ableton for the life of me. I tried setting them to different channels but I get nothing. When I hit a pad or key on one of the controller the light in the corner shows up letting me know that live is getting the signal from both controllers yet nether of them will play notes when i open up a synth or drum rack. As soon as I unplug one though it works fine and plays sound within lives instruments. I know its probably just some stupid setting to fix this but i have done a lot of searching and nothing has helped.

Thanks you for your time!

Are they interfering with each other, i.e. both have controllers mapped to the same parameters in ableton?

I got a similar set up. I use both an oxygen8 and a padkontrol hooked up to a usb hub along with my sound card and some other shit and i notice when i got em all on one usually doesnt work but im pretty sure its cuz theres not enuff power available so i gotta turn off my padkontrol if using my oxygen8 or vice versa etc. no biggie tho u can just double click the sound system thing on/off on the top-right to reset if u change smtg. if u do have enuff power u can arm both ur synth and drum track by holding cmd/cntrl and clicking arm button
