Convert MIDI to 669

Understanding MIDI and 669 file formats

MIDI (Musical Instrument Digital Interface) is a standard protocol for communicating musical performance data between electronic instruments, computers, and related devices. MIDI files (.mid) contain instructions for music playback, such as notes, timing, and instrument assignments, but do not store actual audio data.

669 files refer to the Composer 669 module format, an early tracker music file type used in the late 1980s and early 1990s. 669 files store digital audio samples and sequencing data, allowing for playback of multi-channel music, commonly used in the demoscene and early PC games.

Why convert MIDI to 669?

Converting MIDI to 669 is useful for musicians and retro computing enthusiasts who want to use MIDI compositions in tracker-based environments or legacy software that supports the 669 format. This conversion allows for integration of modern compositions into classic module-based music engines.

How to convert MIDI to 669

Direct conversion from MIDI to 669 is not straightforward, as MIDI is event-based and 669 is sample-based. The process typically involves:

• Importing the MIDI file into a tracker or conversion tool.
• Assigning instrument samples to MIDI tracks.
• Exporting or saving the project as a 669 file.

Recommended software for MIDI to 669 conversion

The best approach is to use a tracker that supports both MIDI import and 669 export. OpenMPT (Open ModPlug Tracker) is a powerful and free tracker for Windows that can import MIDI files and export to various module formats, including 669.

To convert using OpenMPT:

1. Open OpenMPT and use File → Import → MIDI File to load your MIDI file.
2. Assign samples to each instrument channel as needed.
3. Once satisfied, use File → Save As and select Composer 669 (*.669) as the output format.

Note: Some manual adjustment may be required to ensure the MIDI data translates well into the tracker format, especially for instrument mapping and effects.

Alternative methods

If OpenMPT does not meet your needs, consider using legacy trackers like Schism Tracker or MilkyTracker, though their MIDI import and 669 export capabilities may be more limited. For advanced users, scripting or using conversion utilities in combination with manual editing may be necessary.
