Hi Pulse,
> How do you have your audio channels configured? Are you sending everything to master within Ableton and then the master channel out to the mixer?
I've included some screenshots of my Ableton preferences, and the ASIO driver settings:




Master out in Ableton is set to outputs "1/2" on the interface.
Interestingly, with the DJM connected and DJM ASIO output selected in Ableton, I get the same problem (audio cuts out after one or two notes max) even using the "Computer MIDI Keyboard" in Ableton, the same result as when I'm using the Push. This is without the Push connected, btw.
Also, it's worth mentioning that even after the audio cuts out, the "MIDI Track In Indicator" light top-right still flashes when I press keys (either on the Computer MIDI Keyboard, or on the Push). Even so, there's no level meter movement, or sound.
Oh and I forgot to mention, I'm on Windows 10 1803.
Hope this is useful extra info?
I think it would be useful for all affected users to be informed when Pioneer have been able to reproduce the issue, separately to any root cause investigation or working on a fix. This might help to narrow down the combination of hardware and software that is at fault?
Thanks!
