Diki, it's true that I'm not a skilled musician. I ONLY play chords with my LEFT hand. But 2-3 ticks is MUCH less than a sixteenth note. In Roland arrangers, a quarter note is allocated 120 ticks. So a sixteenth note would be 30 ticks. The 2-3 tick setback that I proposed is a fraction of that, and on-par with the non-adjustable window that I've observed on some Korg arrangers.

Dengizich stated that he was using "Standard" chord recognition. I recommended the use of "Pianist 1" because I know it won't start computing the chord until at least three keys are pressed. Personally I wouldn't know what to do with a sustain pedal!
