Hi Renoise forum!
Me and my wife are making ourselfs a christmas present.
Let us introduce the Triano!
It’s a midi controlled claviature made from a 100 year old harmonium.
We picked it apart 1 week ago and now we have 12 keys working.
It sends midi commands over the local network when a key is pressed.
To know when a key is pressed we use a microswitch.
Our current status is that we are waiting for 6 more raspberry pi zeroes for the rest of the keys.
