ModRunner 1.0.0

Added

• MMD0 and MMD1 loader, following the pointer discipline the format
  specification insists on, with bounds checks on every structure
• Paula-style replayer: four or more voices, Amiga period table, per-voice
  looping, Catmull-Rom resampling, soft clipping
• Effects 0x00–0x0F, including the 0x0F misc group and the $80–$C0
  range of 0x0C that rewrites an instrument's default volume
• Extended MMD1 effects 0x11–0x1F: single-tick pitch and volume slides,
  ProTracker-style vibrato, set finetune, line loop, cut note, sample start
  offset, jump to next sequence entry, replay line, note delay and retrigger
• AmigaOS 3.x style interface: bevelled panels, per-voice VU meters, transport,
  song position scrubbing, playlist with drag and drop
• Tracker view showing the current block's note data under a fixed playhead,
  toggleable and remembered between launches; the window resizes to match
• Module statistics in the status line: blocks, lines, notes, samples
• Switchable visualisation: per-voice levels or an oscilloscope of the output
• Display synchronised to the speakers, compensating for output latency
• The window position is remembered, separately per skin, and discarded when it
  would land on a screen that is no longer attached
• ProTracker .mod support, loaded into the same model and played by the same
  replayer; the effect dialect is carried on the module, since the command
  numbers mean different things in the two formats
• The Amiga output filter, switchable and remembered between launches
• Per-channel mute and solo
• Opens modules from the command line and from the Finder; .med and .mod
  are declared as document types with their own UTIs, and make associate
  registers ModRunner as their default application
• Offline-rendering test suite and a WAV export for listening checks
• Four example modules by the author

Notes

• MMD2 and MMD3 are detected and reported rather than played
• Synthetic, hybrid and MIDI instruments are parsed but stay silent; hold/decay
  (0x08) and synth jump (0x0E) are not implemented
• Playback verified against libxmp: 0.985 envelope correlation at zero lag,
  duration within 0.4 s over a 3:27 module
