Thank you very much this solution may fix my problem ,but let me try working on my keyboard to test it because as I mention this issue accrue from time to time not every time...
thanks again
thank you for your reply...
no I'm sure I'm not holding any key or etc...do you think this issu be a hardware problem?..because when I restart triton the problem will fixed..
I upgraded to last firmware 1.0.6 and restore to original setting and same problem remain..
many times when I'm working on my triton in sequencer I can't change tracks ,I have to save the project then power off the keyboard and power on it again to countinue my work..I don't attach any external device expect the Compact flash 1GB...
