Unlike most FM synthesizers that are very clean and digital, the vintage FM chips within MEGAfm have very characterful tone allowing a broad sound palette ranging from beautiful plucked strings to growly distorted bass lines.
Jan 2023 update: Happy new year! A new small batch is being assembled. Orders will open Saturday Jan 7th at 8PM Paris time and will ship in February.
Hardware FM synthesizers are infamous for their reduced controls and complexity to program, with tiny LCD screens and only a couple of buttons to operate a load of menus…
With its 32 operators faders, 14 knobs and 15 buttons MEGAfm offers unprecedented hands-on FM control!
Every knob and fader can easily be modulated by the easy to use LFOs.

Please check the video below for firmware update instructions (5:13)
Starting September 2022
This updated version is identical in appearance and functionality but will include a pair of YM3438 chips instead of the YM2612. The YM3438 is a variant of the YM2612 that is identical in functionality and was featured in the Sega Megadrive II. The circuit layout has also been updated to grant access to the FM chips with minimal disassembly.
Indeed the chips are now socketed (removable) and accessible by removing the bottom panel.
This allows you to install alternate FM chips (like the YM2612, modern alternatives or even custom sound chips).
You can also mix different versions of FM chip as there are 2 slots that can be configured individually.
MEGAfm MKII features the same audio circuitry and analog distortion as the MKI, as a result both chips sound very similar inside of MEGAfm.
The firmware will work identically on both versions.
