span.dur is a uint16_t, so a delay longer than 65535 samples wrapped: at 44.1kHz that is any gap beyond 1.5 seconds, and a held note or a rest of ordinary length came out far too short. The conversion overflowed too, because delta * sample_rate does not fit in 32 bits for a long delay. Compute the duration in 64 bits and carry whatever does not fit in span.dur in a separate field, handing it over a chunk at a time. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

span.durin a separate field, handing it over a chunk at a time.Verification. Builds clean on arm and xtensa. No hardware; this path is timing-only and I could not measure it on a device.
Size. About +160 bytes of flash on nrf52840, plus four bytes per
MidiTrackobject.Stacked on #36.
