About

Synfact

Synfact adds machines and modules to the Elektron Syntakt. This site builds it entirely in your browser: the official OS file you supply is checked by its hash, patched and verified locally, then offered as a download or sent to your instrument over Web MIDI.

Before you install

This is experimental, unofficial firmware. It is not made, endorsed or supported by Elektron.
Back up your projects, sounds and samples first.
Read the recovery instructions before installing.
