Chris,
Congratulations on the mechanism design -- ingenious!
The vertical bar just right of center -- is that in fact a rocker arm that pivots on a lifter that is raised when the octave key is pressed?
If so I think I understand that when LH3 is down, then the upper end of the bar is held down, and the 1st octave key must open. But when LH3 is up, what forces the 2nd octave key to open? Is it relative spring strength between the two octave keys? Or am I way off track?!
Cheers,
Gerry
