- This repo is obsolete, I've left it here for reference... please have a look at my latest version, newdigate/teensy-eurorack
- record midi events from a physical midi input port to standard midi files (SMF) on SD-card
- play smf files from SD-card to a physical midi output port
- display midi input & output activity, indicators (tempo, key, signature, position) on small color TFT display

The project is a work-in-progress in a very early stage of development; I have working prototype using breadboard, as diagram above, records successfully to smf midi file on sd card which can be read from midi players and daws.
