What's new in 0.13

• PROPHET, a new engine for Sequential Prophet-5 Rev 4 programs: two oscillators with hard sync,
  Poly-Mod, LFO and noise wheel modulation, the SSI (Rev 1/2) and Curtis (Rev 3) four-pole filters,
  separate filter and amplifier envelopes, Vintage, glide, unison and five voices per track.
  All 200 programs of Sequential's v1.03 factory bank are its presets. LFO rates, vibrato depth,
  filter tracking and envelope times are fitted to recordings of a Rev 4. Sixteen device pages edit
  every native parameter, and 128 native user slots (P001–P128) start with the first 128 factory
  programs. The web editor imports and exports Prophet-5/10 .syx programs and banks; the device also
  accepts single and edit-buffer dumps over USB. PROPHET takes ANALOG's place in the engine list
• Note editing: SEQ > NOTES is now the single editor for entered steps and recorded takes:
  SELECT walks the notes, the knobs change pitch, length and velocity, SCL moves and EDIT deletes;
  hold EDIT while recording to erase as the playhead passes
• FM6: DX7 librarians can send 32-voice banks straight to the device over USB, into F001–F032
  or F033–F064 (EDIT > STORE > SLOT), and bank dump requests answer from there; STORE > SEND sends
  the track's voice. The fourth main knob is DTUN
• Performance: engine and bank memory is allocated when it is used, idle USB capture and silent
  tracks cost no processing, and the screen draws while the LCD transfers
• Retired engines: PHYS, TRIO and WHEEL. Tracks that use them are silent; their saved values are kept

Upgrading from 0.12: projects, templates, banks and presets migrate. Projects and templates saved
by 0.13 include their Prophet programs and need 0.13. Installing 0.12 or the official V15 afterwards
erases the Prophet user slots: export them, or keep the installer's backup, first.

Install

Connect the FM-1 by USB and open the web installer in Chrome or Edge. The installer saves a full backup before updating. For a local install, run python3 tools/fm1_install.py melodee-0.13.fwsc. The installed release reports FM-1_9013.

Files

• melodee-0.13.fwsc: installable firmware package
• melodee-0.13-app.bin: application image alone
• melodee-0.13-licences.zip: license and attribution texts for the firmware, bundled components and included sound data
• SHA256SUMS: SHA-256 checksums for the three downloads

Validation

The firmware source passed the full host suite before release, including the Prophet engine (native frames, all 200 factory programs rendered and health-checked, measured LFO rate and vibrato depth), editor protocol paging, note editing, migrations, UI, audio, performance and web tests. PROPHET's LFO, vibrato depth, filter mapping and envelope times were fitted to a recording of a Rev 4; LFO-to-filter, Poly-Mod-to-filter and attack scales are still estimated. The 0.13 release package passed build and update-loader checks and was installed on an FM-1, which reports FM-1_9013; the same feature build's 201 Prophet preset names were read back from the device. Device CPU timing of the final PROPHET DSP and hands-on musical validation of the versioned release remain unverified.
