Synth: Nord Lead standalone release preparation - #559
Conversation
📝 WalkthroughWalkthroughAdds an alpha Clavia Nord Lead adaptation for Nord Lead 1, 2, and 2X. The change supports SysEx detection, program and edit-buffer handling, MIDI legacy loading, build installation, documentation, and fixture-based testing. ChangesClavia Nord Lead adaptation
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to Users may attempt unavailable live-bank downloads, and malformed legacy MIDI files can appear to import successfully while silently omitting invalid content. Clarify the hardware limitation and reject malformed escape-framed SysEx before merging. Sequence Diagram(s)sequenceDiagram

Validate explicitly framed SysEx in F7 escapes before appending it.
Line 287 bypasses the embedded-status-byte validation at Lines 293-295. An escaped F0 ... 0xF8 ... F7 message is malformed under this parser’s policy, but it is appended and later filtered as a non-Nord dump. If earlier dumps are valid, the loader returns a partial import instead of raising ValueError.
Proposed fix
escaped.append(byte)
if byte == 0xF7:
+ if any(data_byte >= 0x80 for data_byte in escaped[1:-1]):
+ raise ValueError("Embedded status byte in MIDI SysEx")
messages.append(escaped)
escaped = []📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

format shadows the Python builtin in smf and test_midi_multiple_tracks_and_channel_running_status. Rename both parameters to smf_format, including the parametrization name and all references.

Qualify live-bank availability in both device tables.
The adaptation exposes four documented live-request banks, but availability depends on the Nord Lead model and installed memory card. Without this qualifier, users may attempt a live-bank download that their instrument cannot provide. Update both entries in README.md and docs/README.md while retaining the separate ten-bank 2X file import/export support.

Fix Nord Lead MIDI import and remaining PR #559 review findings
1 participant
Summary
Standalone replacement for #550, without the #538/#539/#540 stack. Merged current master, including Fourm #535, and completed release hardening in d2e35a4.
Validation
Release scope
Alpha support for normal Nord Lead 1/2/2X programs. Official files and mock MIDI are tested; hardware detection/timing and writable-memory behavior remain unverified. Live bank availability depends on the instrument and memory card. Higher 2X banks support file import/export only. Percussion kits, performances and Nord Lead 3+ are not supported.
Platform CI and the follow-up review must finish before merging. Original #550 remains open for history until this replacement is merged.
