Check out this midi concertina made with a pic microcontroller.
I researched concertina building — but only for a couple of hours. It took just that long to see that such a project (valves, reeds, bellows…) is WAY beyond my ambition.
Then in one of those “sychronicity” epiphanies, a lot of things at once suggested another approach: 1) My son, the NYU Jazz major, exposed me to MIDI technology. 2) A work buddy enthused about learning Programmable Interrupt Controller (PIC) programming. 3) I ran across Jordan Petkov’s excellent site on building simple MIDI controllers using PICs.

Wow, I have dreamed of this.
This is very cool. I have just taken delivery of a Streb eMelodeon, which is a midi melodeon (2 row button accordion) including the critical feature of pressure switches on the bellows; attack and volume are controlled by bellows movements just like they would be on a real instrument.
That too is a hand-crafted product; mine is no. 22 and I think Steve makes about one a month.
I wonder what you could do with an accelerometer on this instrument.
So, does this use a microchip brand PicMicro, or does it use a programmable interrupt controller? They are not the same thing…

Its a PIC 16F84 by the looks of it … the assembler source code is linked to the link…
Cool project! But what does it sound like? Are there any links to a sample sound file?
