You can find the M-VAVE FM-1 on Amazon.

"Another day of AI-sloping firmwares for FM-1, this time a fair lo-fi sampler with 120s of audio, zones/instruments mapping, a free loop sequencer, punch-ins and send-returns. Still not LOOPA but already closer"

fm1-lofi

A lo-fi sampler that runs on the M-VAVE FM-1 itself, plus a web editor (one HTML file) that builds sample packs and sends them over Bluetooth (BLE MIDI) or USB.

Samples are stored in the FM-1's flash as 16 kHz mono, 2 bit LMS-ADPCM: about 100 s of audio in the 520 KB the firmware has for a pack.

The panel is a menu of ten screens (FX, SEL, ENV, LFO, EDIT, GLO, HOME, SAVE, ARP, SEQ), each with four parameters. Keyboard zones, scales, per zone envelope / LFO / start / end / reverse, four send effects with punch-ins, an arpeggiator and a live loop sequencer.

The web editor (one HTML file, any Chrome or Edge, Web MIDI) imports audio, slices it, maps it to zones, previews the real 2-bit sound and uploads the pack.
