When I initiate recording I get my metronome count-in as per my settings, then on the first beat of recording I hear one “piano” note play (C3) - it’s just slightly off beat. I’ve scoured the settings and can’t find anything that matches the behaviour.
Double-check the Studio > Studio Setup, please. Do you use any Remote Device here? Isn’t the Output of any Remote Device routed to your hardware (or where does the “piano” comes from)?
Yes I have a remote device, my MX61 keyboard doubling as controller and sound source. The sound is coming from the MX61 - but I can’t figure where it is being triggered from.
First of all, I would change the Studio > Studio Setup > Remote Device > Yamahas MX… > MIDI Input from the All MIDI Inputs to the Yamaha MX Series… MIDI Port.
If this doesn’t help, set the MIDI Output of this Remote Device to Not Connected, please.
