What TILT-FM does

  • TILT-FM is multi-engine synthesizer firmware for the M-VAVE FM-1, built on Felucca's interface.
  • The ANALOG, LOFI, TRIO, WHEEL and NOISE engines supply the sounds.
  • Hold ENV to reach the TILT layer and its quick-start tools.
  • NEW SONG gives you a key, scale, tempo and four role-aware sounds, with HOLD, NUDGE and START.
  • STUCK applies RANDOM or COOK to the current track to break a stall.
  • The TIMER runs a session with a TIME ending and captures a timed take.
  • Connect the FM-1 to a computer by USB and use the web editor.
  • The update loader lets you move on to another firmware or back to the official V15.

  • It doesn't show up as a USB drive or network adapter

What we found
