I've looked all over the forums for an answer to this problem and can only find one person reporting a similar problem but they did not get help.
I'm running the most current version of Live. Trying to use my DJM-900 nexus as an audio interface for production (Audio Device "PIONEER DJM-900nexus ASIO"). Audio is working just fine, but MIDI is only half working. If I play a MIDI clip the sound comes through but if I arm session recording on the MIDI track and try to play some notes there is no sound. When I first noticed this I figured it must be a sample rate issue. So, in Live, I set the sample rate to 48000 (the only sample rate I am able to select in the DJM-900nexus Setting Utility) and in the setting utility I increased the buffer size to 1024 Sample (the only buffer size it will allow in Ableton). Restarted Ableton and made a new MIDI track, armed recording, played a note, and this time audio came out, but as I released the MIDI trigger, the note did not stop. The sound sustained as if I had never released the MIDI trigger and all MIDI tracks became unresponsive to input although Ableton's MIDI track in indicator still continued to light up normally up as I hit triggers. I switched the audio device to MME/DirectX and noted that the sound was still sustained as though I had not released the midi trigger. This problem does not occur when using other audio devices. I can run ASIO4ALL into the DJM and it works just fine but I'd rather use the sound card in my two thousand dollar mixer. I can recreate this problem consistently, even when I use my friends computer that has an older version of Live 9 on it. This is driving me crazy I have messed with every user and club setting I could find on the DJM in attempt to troubleshoot to no avail. Please Help!
P.S. I just updated the DJM to the newest firmware (1.32) and the problem still persists.
