APC40 Triggering Keypress in Ableton Live 9? Control Surfaces

APC40 Triggering Keypress in Ableton Live 9?

I'm having a very strange issue with my APC40 with audio playback. On channel 1, the volume fader fluctuates pretty wildly inside of Ableton.

1. I create a new Ableton project.
2. I load two identical audio clips in channel 1 and channel 2
3. I play the scene. The volume fader starts going wild for channel 1 (it will just fluctuate between 0DB and -30DB) yet it stays normal for channel 2.


- There is no automation
- I can see the "Key Map" mode going wild during playback so it's clearly receiving a midi signal from somewhere.
- I attached the midi set up.
- I uploaded a brief screen cast of the problem here: (note the volume movement on channel 1 and the input feedback beside "Key" in the top right).

Has anyone experienced this before? Does this seem like the APC40 has crapped out?
