ARMK2 + A4MK2 glitch out when MIDI-ed together

As soon as I hit play on either machine, they both start glitching out (both freeze no audio, and the lights start blinking erratically, tempo light goes crazy).

I suspect some sort of MIDI syncing/feedback issue cause I can just slave the A4 to the Rytm with one cable and it works fine. I just lose transport control from the A4.

Any ideas?

Setup:

A4MK2 1.35B
ARMK2 1.45

AR > MIDI out > A4 MIDI in
A4 > MIDI out > AR MIDI in

AR checked: Clock Send, Transport Receive, Transport Send
A4 checked: Clock Receive, Transport Receive, Transport Send

Off on both: Receive notes and receive CC/NRPN

Something wrong, you send and receive Transport on both.
Uncheck Transport Receive on AR, and Transport Send on A4.

If off, with don’t you use only one cable?

They should both be able to send and receive transport from each other. That is the issue. Unless I’m wrong, but I think that is a normal function between machines?

I just want transport control from both machines, don’t need notes or CC messages from either to go to the other.

There’s usually a master and a slaved machine.
Try to uncheck Transport Send from A4 to check if it’s the glitch out reason.

Ya it works just slaving the A4 to the AR. I sent in a support ticket. I seem to remember it working fine before the last update. Thanks for the help :slight_smile:
