Hi there,
With last OB version (2.8.4) and last A4 firmware (1.51C)
Steps to reproduce:
- Open A4 plugin in your DAW
- Send note on Midi channel 1 => works OK
- Activate arp on track 1
- Send note on Midi channel 1 => does not work (no sound emitted)
- Deactivate arp on track 1
- Send note on Midi channel 1 => does not work (no sound emitted or very short sound)
- Use chromatic keyboard on A4 hardware to play a note => makes sound
- Send note on Midi channel 1 => works OK
So it’s like activating the arp and playing the track from the host makes something hang. And that can only return to normal by playing the keys on the A4.
