FMS - Handheld FM Groovebox

US 2OP Synth & Sequencer for Game Boy Advance      06/05/26

When it comes to portable music making, we are spoiled for choice - with the likes of the Dirtywave M8 heading up the high end options (HDMI out and SD card storage), Nanoloop covering a wealth of formats, the forefather LSDJ on Gameboy and now FMS for the Gameboy Advance! FMS will also run in an emulator (even on mobile devices) and on other compatible hardware). All the specs and details are below - it looks like a very fun little platform given the $10 price tag!

FMS is a groovebox built for the Nintendo® Game Boy™ Advance handheld video game system. Its focus lies on quick and intuitive control of programming sounds and music, for live performance and studio recording - or just having a blast.

While it's built for the GBA hardware, it can be run on all kinds of old and new devices since emulators are both widespread and accurate. Computers, phones, Linux handhelds, FPGA systems, game consoles - FMS runs almost anywhere.
