My chamber organ
Orbert:
Paul, you are beyond awesome. I'm not sure what comes next, but I'm thinking you're at least two settings past "awesome" on the scale.

Whereas the others have 8x8 diode-matrix wiring

Why? Just curious.
Also, I just noticed that you call them "keyboards", which is how I think of them, too. But wouldn't they more properly be called "manuals"?
pwhodges:
A keyboard for the hands is also a manual; a keyboard for the feet is also a pedalboard. I think of them as manuals/pedalboard when considering them functionally while playing, and as keyboards when wiring them up.
To matrix or not? Basically it was a matter of the most economical arrangement of circuit boards, using a range from a guy in Poland. Also, having done two manuals and pedalboard using a matrix, I got fed up with the amount of soldering; the direct wiring may have four times as many wires, but using ribbon cable as I do makes it easy, neat and tidy, and with less solder joints to make. The chamber organ keyboard is a different construction which has the common bus-bar as the fixed part of the contacts; the mounting arrangements for that bar make it impossible to divide for matrix wiring, because it would simply fall apart.

That is a heroic amount of work to put into something you only needed for one occasion. (Although reading the post it's obvious that it can be used for any occasion)
You are a true man.

^^^ That, 100%!

Makes sense. Also, I guess I never thought of pedalboards as keyboards, but they are, aren't they? I've only ever heard them called manuals and pedals (or pedalboards).

Awesome work. How did you acquire the knowledge necessary? Is there a organ-building guild in your town or... huh? :evil:
Also, one thing that struck me: Is it really that hard to transpose a song or just play the songs one half-step down on the keys? Or am I missing something?
