Convert ARR to CPR

Understanding ARR and CPR file formats

ARR files are typically associated with Atari ST music tracker files, used by programs like Audio Rasterizer or Arkos Tracker. These files store music patterns, instrument data, and sequencing information for chiptune or retro music production.

CPR files, on the other hand, are most commonly known as Capella Score files, used by the Capella notation software for music notation and sheet music. They contain musical scores, notes, and layout information for composers and musicians.

Why convert ARR to CPR?

Converting an ARR file to a CPR file allows musicians to transfer music created in a tracker environment into a professional notation format. This is useful for editing, printing, or sharing sheet music with others who use Capella or compatible notation software.

How to convert ARR to CPR

There is no direct converter between ARR and CPR formats due to their different purposes and structures. However, you can use an intermediate format such as MIDI to bridge the gap:

1. Export ARR to MIDI: Open your ARR file in a compatible tracker (such as Arkos Tracker or Audio Rasterizer) and use File → Export → MIDI to save your music as a MIDI file.
2. Import MIDI into Capella: Open Capella notation software and use File → Import → MIDI to bring the MIDI file into Capella, then save it as a CPR file.

Recommended software for conversion

• Arkos Tracker (for ARR to MIDI export)
• Capella (for MIDI import and CPR saving)

Both programs are available for Windows and offer trial versions for testing the conversion process.

Tips for successful conversion

• Check instrument mapping after MIDI import, as tracker instruments may not always translate perfectly to notation software.
• Edit and adjust the score in Capella to ensure correct notation and layout.
