Minimal C64 music player
9-rasterline player with limited featureset.
- Wave / pulse / filtertables with "next column" instead of jumps
- Delayed step, slide (indefinite) and vibrato commands in wavetable
- Pulse and filter tables are based on "destination value compare" instead of time counters
- Normal & legato instruments
- Keyoff command
- Change wavetable-pointer command
- Transpose
- Sound FX support, either overrides the channel completely (faster) or allows music to continue underneath
- Support for several music modules with the same player code, similar to NinjaTracker gamemusic mode.
Disadvantages:
- Only 1 frame of gateoff before new note (does not guarantee proper hard restart)
- Skips all realtime effects when reading new note data
- Pulse & filter tables can be only 127 steps, due to high bit of position indicating "init" step
Converter from GoatTracker 2 format included. See the player source (player.s) for data format details. Supported effects are 1,2,3,4 and F (no funktempo). Effect 3 (toneportamento) support is based on calculating the required slide duration, and may not work exactly in case of transposed patterns.
Use at own risk.
