Apple Silicon M1 IAC Driver

VCV Rack

Anyone using IAC Driver on Apple Silicon M1?

It plays the first few bars, but then stops playing.

Please give me some advice.

[Operating environment]

Logic pro→IAC Driver→VCV Rack Free 2.1.2 (no good)

I have not had any issues sending MIDI from Ableton to Rack via the IAC Driver. I’m on an M2 Mac Studio and an M1 Macbook Pro.

I use IAC a lot on an m1 machine, very reliable, all versions of rack - your issue is probably something silly like it is most of the time, maybe some midi loopback?

thank you for the message. It seems to be a Logic configuration issue.

thank you for the message. It worked normally when IAC Driver was removed from Logic’s MIDI settings. It seems that MIDI LOOPBACK was the cause.
