Player + Importer 0.2

Player + Importer 0.2: the MCS player grows a chiptune importer —
Vortex Tracker .pt3 modules (ZX Spectrum / AY-3-8910) convert to
playable MCS songs.

New: Import (⬆ Import… in the toolbar, or mcs-convert convert)

• Import Preview dialog — per-channel note counts, pitch ranges, noise
  stats and percussion verdicts, with ▶ solo audition per channel and a
  preview of the checked mix, so your ears make the final call
• Percussion handling — AY drums (detected from the modules' sample
  tables by noise duty cycle and usage) can be synthesized as clicks
  (dissonant-cluster or wood-block timbre), played as written pitches,
  or dropped; drum clicks are pinned to their register through octave
  shifts
• Per-channel octave shift and an MCS tempo picker (row rate mapped
  onto the 1984 tempo table)
• Decay shaping (optional) — truncates notes to their sample's audible
  decay, recovering plucks and staccato that MCS's volume-less voices would
  otherwise smear into legato
• Pattern-order repeats are fully unrolled; converted files play in the
  original program (one clean pass — no loop)

Also

• Ties are now decoded per note (matching the engine's tie handler),
  improving chord fidelity in original songs
• The general Song → MCS encoder behind the importer is verified by
  re-encoding the Maple Leaf Rag demo losslessly
• Docs corrected: the test corpus is the 12 songs of the original retail
  disk plus user-made songs collected over the years (86 files, all
  round-tripping byte-identically)

Download

• MCS-Player.exe — standalone Windows build (no Python needed).
  SmartScreen will warn about an unrecognized app: More info → Run anyway.
• MAPLERAG.MCS — the public-domain Maple Leaf Rag demo song
