M400 3 Violin Tuning
2007-06-18 by john barrick
So, has anyone kept a record of how badly the M400 Three Violins are out of tune with each other and which keys are the worst offenders? I've got 1407 back together and playing and I'm down to minute keyboard adjustments and I'm wondering if there are certain notes that I just shouldn't attempt to put that much time into. Most notes sound OK as you're running up or down the keyboard, but if I try playing something in unison an octave apart or certain chords, it becomes obvious there are still some tuning problems. As my pinch rollers are finally spinning like they have ball bearings, I guess I should check motor stability and the SMS4 to make sure that issues aren't originating there. john
