Saadet 0.1.1

Fixes MIDI clock drift during input queue overflow and arpeggiator catch-up after clock bursts. Backported from Melodee 0e3d353 for USB, TRS and Bluetooth MIDI.

Saadet retains its 44.1 kHz audio configuration.

Automated validation covers repeated overflows, two-hour clock sessions across timer/counter wraps, transport changes, swung arpeggiator phase/gates, the full host and base-port suites, firmware packaging and source/licence checks. Physical validation of this exact package remains pending.

Install using the web installer, or download the firmware below. Matching source, checksums and the installer site are included.

See RELEASE_NOTES.md in the release bundle for installation details and known limits.

Saadet 0.1.0

Saadet 0.1.0

First public release for the M-VAVE FM-1, with Bluetooth MIDI enabled.
This is an experimental release; the outstanding hardware checks are listed below.

Included

• One polyphonic synthesizer with Prophet, FM6, CZ-1 and JUNO-106 engines.
• Native tone editing, SysEx import/export, factory sounds and 384 shared user sound slots.
• Arpeggiator, HOLD, chords, strum, scales, microtonal tuning and MIDI expression.
• Native 24-bit audio, stereo USB playback and synth-master capture at 44.1 kHz.
• USB, TRS and Bluetooth MIDI. GLOBAL > BLE manages the phone/computer link;
  GLOBAL > DEV discovers and connects an external Bluetooth MIDI device.
• The last successfully connected outgoing MIDI device is remembered and retried after boot or connection
  loss, with increasing delays up to 30 seconds. Disconnect and Radio Off stop retries; Forget clears it.
• Automatic last-sound recall, complete Saadet backups and a browser-based USB installer.
• Optional m-bootloader 1.2 recovery, installed separately after the application.

The firmware uses MPL-2.0 with the retained third-party terms documented in LICENSING.md. The editor and
some tools retain GPL-3.0-only. The downloadable source includes the matching application and pinned
fm1-base/felucca-bsp source; vendor factory sound data keeps its own attribution and terms.

Installation

Open the installer in Chrome or Edge on a supported computer, connect the FM-1 by USB and follow
the installer. Back up any sounds you want to keep. m-bootloader is optional and off by default. If selected,
it is written after Saadet; keep USB and power connected until completion. See BUILDING.md for recovery.

Saadet is a single-part synth. Installing and saving over Melodee can replace its former project A data;
Melodee project backups are not Saadet backups. Preserve a backup before switching firmware families.

Known limits and validation

Devices that rotate their private Bluetooth address may need to be selected again. Incoming phone/computer
connections are initiated by the host; automatic reconnect applies to the outgoing MIDI-device link.

Automated checks cover native engines/audio, MIDI, storage, UI, BLE protocol and reconnect policy, installer
transfer/resume, bootloader handling, source/package consistency and licence notices. Hardware records include
successful displayed-code iPhone pairing and a MIDI subscription on an earlier build.

Final acceptance of this exact 0.1.0 package on an FM-1 remains to be recorded:

1. Install and confirm the release identity FM-1_9000100 and the on-screen version.
2. Play and receive BLE notes, sustain and pitch bend; check that disconnect leaves no stuck notes.
3. Reboot and test the remembered outgoing device, retries, manual Disconnect, Radio Off and Forget.
4. Exercise USB/TRS/BLE together while playing all four engines, and check audio continuity under load.
5. Save/reopen sounds and settings, and check the normal update and recovery path.

The preparation tools do not install or publish anything. BUILD_INFO.json and SHA256SUMS identify the exact
package and corresponding source; VERIFICATION.json records the completed automated preparation checks.
