TEE1010 Part 7 - MIDI Out - An FCB1010 rebuild with a Teensy 4.1

I’m am rebuilding a FCB1010 into something that is more capable. To do this I have gutted the internals and installed a Teensy 4.1 and Teensy Audio card. I have delusions of it working like a bass pedal, MIDI sequencer and/or drum machine.

A quick video showing the MIDI out working.


Hi John,

Looks great, I’d suggest submitting a project write-up to the website for the store credit reward if you’d like to, hopefully, someone else in the future putting their own project together can learn from your project! All the info to share it is on this page, please let us know if you have any questions:


I will look into it when I am finished. I still have some things to do…
