Schumann MIDI arrangement: source and method

A worked demonstration. Schumann’s Mélodie, Op.68 No.1: genuine five-credit development reading → checked version → actual browser download from the development MIDI exporter → real LMMS import and native project saves.

The same complete four bars, at 80 BPM

The whole right-hand layer changes instrument, including its dyads and inner voice. Every pitch, onset and duration stays intact. Both excerpts use the same fixed +12 dB gain; instrument patch levels remain native. A 10 ms fade ends the 12-second boundary.

The soundfont path in these projects points to the installed TimGM6mb.sf2. No synthetic replacement audio was substituted.

Source and correction burden

20 written bars; first four repeated, giving 24 performed bars and 72 seconds at 80 BPM. All 303 imported events match the publisher reference exactly: 118 RH and 185 LH. No import timing quantization occurs for this quarter/eighth-note piece.

• M4 LH final A3 corrected to source G3; repeated performance affected two events.
• M8 upper F5 dotted-quarter assigned to principal RH voice, moving lower A4/C5/B4 to RH2; pitch/rhythm unchanged.
• Six printed espressivo symbols had been read as short nested crescendo/diminuendo tags. Removed unsupported short swells rather than substituting accents; retained actual long diminuendi at M7 and M15.
• Added initial p to LH so piano dynamic applies to both staves.
• Intentional line-continuation slur starts retained.

Boundaries that must survive into the story

• Printed fingerings, pas vite text and six espressivo signs are not represented by this MIDI handoff. No expressive-performance or editorially identical notation claim.
• The publisher also supplies MIDI. This is a worked PDF handoff example, not a lost-source or real-client case.
• No human acoustic endorsement. Native render files are available for listening.
• LMMS MIDI import does not provide a notation editor. Proof is an editable production layer.

The exporter fix is available in development only. The export improvement shown here is not yet available in production.
