How to Use 1Raster-Tracker Music Converter for Seamless Format Conversion

1Raster-Tracker (aka One Rasterline Tracker, for C64) is a niche tracker and converter designed to export SID/SWM-compatible outputs from compact C64 tracker projects. This guide assumes you’re using the 1raster-tracker v1.0 toolset (Windows/PRG/D64 releases commonly distributed) and want a reliable workflow to convert tracker data into playable SID/executable or common audio formats.

What you need

• 1Raster-Tracker package (PRG/ZIP/D64). Download from the project page or scene archives (e.g., CSDB, SourceForge, author site).
• A Commodore 64 emulator that can run PRG/D64 files (VICE recommended) or tools to extract/convert SID files.
• Optional: SID player/editor (e.g., SIDWizard, SIDPLAY2), ORMconvert.exe (for MIDI/SWM conversions), and a WAV recorder (emulator audio capture or SID player export).

Quick overview of capabilities

• Native editing and export of tracker songs (PRG/D64).
• Export options: SID files, executable XEX/PRG, SWM/SID-Wizard formats, and direct SID playable binaries.
• MIDI import/export support through prepared MIDI (used with external converters).
• Small, raster-optimized player routines suitable for demos and C64 releases.

Step-by-step conversion workflow

1. Install and open 1Raster-Tracker

   • Unzip/download the distribution and run the included PRG in a C64 emulator (or run the Windows front-end if provided).
   • If using a Windows executable front-end, launch that; otherwise load the PRG inside VICE (File → Autostart disk/tape).

2. Load your tracker file

   • Use the tracker’s file menu to open an existing .prg/.d64 or the provided song files (.orb/.orm or included formats).
   • If you have third-party module files (MIDI, MOD), import them only if the tracker supports that format; otherwise convert externally to a compatible MIDI (2-channel recommended).

3. Edit/adjust for raster limitations

   • 1Raster enforces tight CPU/rasterline limits. Keep patterns short, avoid heavy real-time effects, and prefer simple envelopes/detunes.
   • Use the tracker’s detune, vibrato and waveform-arpeggio tools deliberately—these are optimized for the single-rasterline technique.

4. Export target format

   • For SID binary:
     • Choose “Export SID” (or equivalent). This typically generates a .sid or .prg/.xex that plays the tune on real hardware/emulator.
   • For SIDWizard/SWM:
     • Use the SWM/SIDWizard export option if you plan to further edit in SID-specific editors.
   • For WAV (audio file):
     • If the tracker or accompanying tools don’t render WAV directly, run the exported SID/PRG in VICE and record audio output (Settings → Sound → Record WAV), or use a SID player that supports rendering to WAV.
   • For MIDI-based workflows:
     • Prepare 2–3 channel MIDI that matches your channel mapping. Use ORMconvert.exe or the tracker’s MIDI import pipeline if available; then export as above.

5. Test the output

   • Load produced .sid/.prg/.xex in VICE (or a hardware SID player) and verify playback.
   • For WAVs, listen for artifacts and verify levels; re-render at higher sample rates if needed.

6. Troubleshooting common issues

   • No sound in emulator: ensure required emulation libraries (SID core settings) are enabled in your emulator and that the PRG was autostarted properly.
   • Export missing channels/effects: simplify pattern complexity or split effects into separate patterns—1Raster’s player may drop operations that exceed raster-time.
   • MIDI import artifacts: use 2-channel MIDI and put FX automation in the tracker’s FX channel rather than relying fully on MIDI mapping.

Tips for the best results

• Compose with the raster constraints in mind: minimal per-line CPU, efficient use of instrument envelopes and arpeggios.
• Keep one channel dedicated to special effects or waveform changes to avoid timing collisions.
• Use emulator WAV capture with a higher sample rate (48 kHz or 96 kHz) for clean audio exports.
• Save iterative exports so you can A/B test minor changes to pattern length, instrument envelopes, and detune values.

Example minimal workflow (recommended)

1. Create/edit song in 1Raster-Tracker.
2. Export as .prg/.xex or .sid.
3. Load exported file in VICE → Settings → Sound → Record WAV → play entire song to render.
4. Edit and re-export if timing or FX are lost.

If you want, I can produce a short checklist tailored to your OS (Windows/macOS/Linux) and preferred output (SID, WAV, or XEX).
