Ableton Forum

thanks for this post, this has been driving me nuts for the last 2 weeks. I use and apc40 and and oxygen 25 together.

I am using an APC40 and an Oxygen 25 keyboard simultaneously. Sometimes it works and sometimes it doesnt. Sometimes Ableton doesnt recognize the APC, other times the Oxygen keyboard just turns off in the middle of a song. Sometimes it works perfectly. Any ideas?
