Description
Precompiled .hex firmware for the Teensy 4.1 with the M8 sequencer, sampler and synth engines. Samples are read from a microSD card in the /Samples directory; the repository recommends FAT32 and a card with good random-read speed. Setup is covered in the M8Docs headless guide. The repository's changelog lists the 6.6.3 series as fixes for MIDI sync, trig envelopes and the FM synth, plus a recording dropout mitigation.
Install notes
Flash the .hex from the repository's Releases folder to the Teensy 4.1 and run a display and input client on the host. See the setup guide.
