Hi!

Just wanted to share a little hack of mine - my main keyboard is a gutted Studiologic 990 but I was not happy with the keyboard 'brain', so I rolled my own.

https://bitbucket.org/ulph/fatar88lux

It's based on a teensy 3.6, and has some good features like release velocity, multiple (extendable easily with code tweaks) pedal support, and some silly features like adding pitch wheel 'noise'...

It's by no means pretty code, but as I think this could be very useful for someone tinkering or as inspiration I thought I should share.

Thanks Ulph! I've been spending a lot of time with Teensy lately. I've mostly been using it as a USB host for MIDI controllers but going forward it would be helpful to work directly with keybeds, ADCs and switch logic.

I found it rather straight forward actually... discussing this project over at pjrc forums of course they suggested different means of scanning, but I opted for simply using the plethora of IO. It's plenty fast, in fact I had to scale back the scan rate so that the cirtcuit had time to go high/low...

Hello Sir,
I'm working on an midi keyboard project like your Fatar88Lux but with other type of keybed (from a broken Kawai digital piano). I found your work on bitbucket but can not find the Complementary notes / schematics since the Dropbox files has been deleted.
Could you please re-upload and share the project files that were deleted?
Thank you very much!

Interesting project (and yes, I'd love to have access to the missing files too).

Are you aware of this project (and several related ones) which people are getting interested in these days?
https://github.com/jkominek/piano-conversion

This project (like mine) explicitly target piano action, but I don't see one could not use it with any kind of salvaged action. There is at least one person who is doing (with different hw and sw) something similar with the Kawai GF action from a electronically fried Concert Artist. See https://pianoclack.com/forum/d/238-anot ... er-project for details.

EDIT: also, a major advantage of rolling your own is that polyphonic aftertouch becomes relatively easy, whereas is very hard to get in a bought controller.

Awesome, I've been thinking of doing something similar with the keybed in my Novation 61 SL Mkii

88 key fatar keybed using Teensy 3.6, countinous pedals and etc.
