Random pitch jumping with midi guitar 2

I HAVE BEEN USING MIDI GUITAR 2 WITH LOOP2MIDI AND A MORNINGSTAR MC6 PRO WITH NO PROBLEMS. SUDDENLY THE MIDI SOUNDS ALL JUMP A SEMITONE RIGHT AFTER I STRIKE THE STRING(S). HAS ANYBODY EVER EXPERIENCED THIS? AND IF YOU DID - DID YOU FIND A SOLUTION?
THANK YOUstrong text

this user had a similar problem, but a whole rather than a half step. it went away after he disconnected some usb devices.

i’m guessing one of those devices was transmitting pitchbend, which wouldn’t have an effect until after the note is played, kind of like what you have going on.

which os? have you tried it without the morningstar connected?
