Interesting thing happened:
Instrument: Alpha
Had 2 or 3 drum loops playing.
Had recorded 2 AUs. Those were playing. (8 bar loop).
Started playing clarinet.
Tonic lights on instrument went out, clarinet sound stopped, loops and recorded tracks stopped.
When I stopped playing the clarinet, lights loops and recorded tracks continued.
I've been able to reproduce this in the same Factory setup (5 split). Did not yet try with another setup.
Glitch, weather, lunar, or other idea?
TIA
Randy
