What's new in 0.13.1

• PROPHET Lo Freq: oscillator B's Lo Freq switch drops it seven octaves instead of ten, as measured
  on a Rev 4 recording, and a new note finds it anywhere in its cycle, as on the free-running original.
  Programs that use it as a slow modulator (Pickle Pincher, FLUTES, TRUMPET FLUTE and others) move at
  their intended rate; Pickle Pincher no longer falls silent after the first note
• PROPHET filter: smoother saturation at the filter's last stage and output removes a faint grain
  that became audible as the filter closed, for example in Internalized's sustain
• Web editor: importing more native .syx programs than there are empty slots offers to overwrite
  them from the selected slot onwards

Upgrading from 0.13: nothing to migrate; projects, banks and presets are unchanged. PROPHET programs
that use Lo Freq or a closing filter sound different, as described above.

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-0.13.1.fwsc. The installed release reports FM-1_90131.

• melodee-0.13.1.fwsc: installable firmware package
• melodee-0.13.1-app.bin: application image alone
• melodee-0.13.1-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 release commit passed the full host suite; only the 201 PROPHET reference renders changed, with no health, voice or CPU-budget failures. In Sequential's Rev 4 factory demo, Pickle Pincher (whose LFO is noise only) moves at 1.31–1.39 Hz; the new Lo Freq range renders 1.34 Hz. On an FM-1 running the release package, Pickle Pincher sounded on every repeated note. With the same DSP on the device, Internalized held five voices at 61 % load (2011 µs worst block, no late blocks or shed voices), and the high-frequency grain under its sustain fell from 47 to 57 dB below the signal. Poly-Mod-to-filter depth and LFO-to-filter/PW scales remain estimated.
