Hello,
New Pro 3 owner here. After combing through forums and the manual, I'm unable to figure out how to effectively use MIDI with Ableton Live and the Pro 3 in certain ways, so figure I'd ask here.
Also, the manual, along with some of the previous posts with this topic vary with older naming conventions in the settings for the Pro 3, so hoping to get help with an updated guide for 2024.
There is no other external hardware involved in this setup regarding MIDI. Just the Pro 3 hardwired directly into a MOTU M4 connected to a MacBook Pro. Also, I知 not using the Pro 3 USB option as I知 currently out of USB ports with my laptop and docking station.
My setup includes the following:
MOTU M4
Pro 3 1.2.0.4
Ableton Live 11.3.13
Physical MIDI Setup:
MIDI Out 1 from Pro 3 to MIDI In on the M4
MIDI Out from M4 to MIDI In on Pro 3
Physical Audio Setup:
Pro 3 Audio Out L + R TS unbalanced cables to MOTU Instrument Line In 1 + 2
Software MIDI Setup in Ableton:
M4 In and Out representing the Pro 3 connections (see screenshot attached)

External Instrument in Ableton (see screenshot attached)
MIDI Settings in Pro 3:
1. MIDI Channel: 1
2. MIDI Clock Mode: In
3. MIDI Clock Cable In: MIDI
4. MIDI Clock Cable Out: MIDI 1
5. MIDI Param Send: CC
6. MIDI Param Receive: CC
7. MIDI Control Enable: On
8. MIDI Sysex Enable: On
9. MIDI Sysex Cable: MIDI
10. MIDI Out Select: MIDI 1
11. MIDI Program Send: On
12. MIDI Program Receive: On
13. MIDI Arp/Seq Notes: On
14. MIDI Arp Beat Sync: Quantize
General Settings on Pro 3:
Local Control: On
With the MIDI track/External Instrument in Ableton armed, I can hit the keys and get audio in from the Pro 3 with any program/bank and hear it fine. I have a separate audio track that I can arm and write to .wav no problem. What I can't currently figure out with the Pro 3 and MIDI in Ableton are two things:
1. Use MIDI clips in Ableton, recording or writing in notes that trigger the Pro 3 and whatever program/bank I知 using. With this current set up, I can't record MIDI notes and when writing them in to a MIDI clip, it does not trigger the Pro 3.
2. Use the Pro 3 Arpeggiator/Sequencer. This one is weird as once I turn on the Pro 3 arpeggiator and hit play under mode Normal, the sequencer doesn稚 do anything. I hit some keys, nothing. Same thing with Gated mode.
Once I use Trigger mode, I can only tap on the Play button and it produces sound, one step at a time with the sequencer. So I知 tapping the play button on the Pro 3 repeatedly to hear the preset sequencer go through each 16 steps as I知 testing this out. Keys do nothing here though. When I have the arpeggiator on and hit play in an Ableton session, still no triggering of the Pro 3 sequencer/arpeggiator.
Can someone help point out what's missing or incorrect with this setup?
Thank you!
