MNM-1

MNM-1 now has its own firmware identity, FM-1_61000100, so The Firmware Hub can distinguish it from other FM-1 firmware. This is a stable identity; the firmware version is reported separately.

• Upgrade from MNM-1 1.0.0 using the attached mnm1-1.0.1.fwsc or the web installer.
• Sound engines, controls and saved-data formats are unchanged. This update does not migrate the optional expanded library.
• The update loader is unchanged and still reports ota-FM-1_900 while updating.
• Screen capture: 240 × 240 PNG, FM+ playing with its audio waveform in the firmware oscilloscope.

Validation: native target build and memory checks; package/app identity agreement; pinned loader; host OTA/loader tests; simulated upgrades from the old identity and back; browser installer and simulator checks. Physical checks on 2026-10-27: 1.0.0 → 1.0.1 → 1.0.0 → 1.0.1 completed successfully; the final USB identity is FM-1_61000100. All four saved banks and settings survived the initial update unchanged. Two bank-A saves passed CRC/readback and reboot checks; banks B–D were unchanged. Sixteen MIDI note-on/off pairs were received without a reboot, voice shedding or core1 timeout. A fresh stock-V15 installation and full stress benchmark were not repeated in this session.

SHA-256 (mnm1-1.0.1.fwsc): d44011bf035314c037e16ab36a8e7895d9274732329e1d60e0bd94bd512eabf9
