Iāve been watching this thread with interest and it has sparked another of my too-numerous-to-mention daft ideas!
I once owned a diatonic button accordion and really enjoyed playing it. But, foolishly lent it to my brother in lawās son a few years back. Anyway, to cut a long story short, he buggered it up so badly it was more or less irreparable.
Since then, I have read about midi accordions, which operate in all respects like a normal accordion in terms of the bellows force affecting volume and bellows direction affecting note pitch. These machines use a midi synthā and on board speaker instead of traditional steel reeds. The advantages over traditional accordions are several fold. Firstly, they can be re-programmed to play different notes and so can mimic every type of accordion set-up. Secondly, they can be played with head-phones for practising purposes. Thirdly, they can use a variety of voices including non accordion voices, if desired.
And then I found out how much they costā¦They start at around Ā£1500!
and so I got to thinkingā¦
I already know how to mimic an accordion treble and bass keyboards using two simultaneously open copies of zynaddsubfx. I already know how to rig up small momentary button switches and map them to keyboard buttons from a previous daft idea when I made a mini arcade machine. All that is left, in terms of gadgetry, is a barometric gauge to measure airflow in the bellows and then redirect this to output volume.
All of the above could be easily driven by a pi, which itself could be easily buried inside a midi accordion case.
Anywayā¦nothing more than thinking out load for the moment
But I know where such thinking always gets meā¦
