What fm1-radio does
- Radio plays internet stations from around the world over 2.4 GHz WiFi, MP3 and AAC streams included.
- KNOB 1 to KNOB 4 pick continent, country, place and station, and MASTER sets volume.
- The 16 white keys are punch-in effects: filters, telephone, bitcrush, stutters, tape stop, reverse, chop, ring modulator, half speed, mute and lo-fi.
- Hold several keys to stack effects, and tap FX in time with the music to set the stutter and chop tempo.
- Press ARP for a 4-voice synth with wave, low-pass filter, attack and release on the knobs, plus octave buttons.
- SAVE keeps up to 16 favorite stations in the FM-1's flash, and the synth settings are kept a few seconds after a change.
- The FM-1 remembers the station and whether it was playing, and picks up there at the next start.
- Over USB the FM-1 is a stereo sound card called RADIO FM-1, so you can record the radio, effects and synth.
