[sdiy] below the surface of keyboards

[Sowa Roman]

I don't think you could find something without a micro, and PIC in specific.
Try those:

http://www.borg.com/~jglatt/hardware/key.htm
and my shameless plug:
http://romcio.multimania.com/small_midi.html
although it's only 3-octave

It is possible to make MIDI keyboard without a PIC - one big
scanning multiplexer, UART and controll logic might do it for you, but
chip count would be much bigger than all above projects combined.

__I recently splashed out on a keyboard in a charity shop: 
__£12.99 ($18US).
__It's 4 Octave-ish, wonderfully compact and in a very nice 
__grey wooden carry
__case. The only thing is I don't know what it's for as it has 
__no contacts
__under the keys and no sockets or brand names anywhere. Maybe 
__a practice
__keyboard? The guy in the store thought it was part of a store 
__display at
__sometime but that doesn't explain the key touch tensioning device.
__
__Anyway I would like to fill it with switches and a MIDI 
__output to put it to
__good use. Can someone point me to a simple schematic 
__somewhere please? PICs
__are OK though I'd like the option of not using them.
__
__Also anyone heard of a unit like this before?
__
__Thanks. I love this list.
__
__Lincoln
