  1. v0.5.0-betaGLIDER 0.5.0 betaBeta2 files

    Beta. Tested on one FM-1 (November 2026). Test reports from more FM-1 owners are very welcome.

    New in this release

    • Button lights: all 14 panel buttons (OCT- and OCT+ included) glow faintly so their labels can be read, light fully while held, and light fully to show the open page (HOME, EDIT, ENV, LFO, SEL, FX), drum mode (SEQ, ARP), a shifted keyboard (OCT-/OCT+), running drums (REC) and MIDI clock (GLO).
    • PLAY is green while the sequencer runs (the FM-1's green PLAY LED), white glow when stopped.
    • PLAY starts / stops the drum sequencer in tone mode too. Hold PLAY for 1 s to switch all tones off (that was a short press before). SEL + PLAY still taps the tempo.

    Install

    1. Back up projects, voices and samples with the firmware that is on your FM-1 now.
    2. Open the web installer at https://subcity.at/flash/fm1-glider/ (or download FM1-GLIDER.html and open it) in Chrome or Edge, connect the FM-1 by USB, choose Device update. Keep power and USB connected.
      • From another FM1 Open firmware (GLIDER, GLITCH, ARPHONY, Official Open) the normal update works.
      • From the original V15 or another firmware: Recovery & force update → Force flash.
    3. Back to stock: same page, Recovery & force update, Restore original V15.

    On an FM1 Open firmware you can also flash FM1-GLIDER.fwsc with python3 tools/flash_fm1.py flash (macOS).

  2. v0.4.0-betaGLIDER 0.4.0 betaBeta2 files

    Beta. Tested on one FM-1 (October 2026). Test reports from more FM-1 owners are very welcome.

    New in this release

    • Own update identity FM-1_8730100 instead of FM1 Open's FM-1_8000014, so tools and the hub can tell which firmware is on a connected FM-1. Tested on an FM-1: switching between GLIDER, GLITCH and ARPHONY, back to the original V15, and from V15 again.

    Install

    1. Back up projects, voices and samples with the firmware that is on your FM-1 now.
    2. Open the web installer at https://subcity.at/flash/fm1-glider/ (or download FM1-GLIDER.html and open it) in Chrome or Edge, connect the FM-1 by USB, choose Device update. Keep power and USB connected.

      • From the original V15 or another firmware: Recovery & force update → Force flash.
    3. Back to stock: same page, Recovery & force update, Restore original V15.

    On an FM1 Open firmware you can also flash FM1-GLIDER.fwsc with python3 tools/flash_fm1.py flash (macOS).
