The Export to MOD feature records your sounds as WAV and produces the patterns so that you can continue your song with any MOD editor, such as OpenMPT.
However, please bear in mind the limitations of the exporter, but especially the MOD format!
Limitations of the exporter
- Only the Set Volume and Reset effects are encoded.
- … that’s all :). No so bad, he ?
Limitations of the MOD format
- Only 31 instruments!
- Only 64 patterns!
- Only 5 octaves! Out-of-bounds octaves are capped.
- The samples must be 8373 Hz, so the PSG sounds will probably sound bad.
- The samples are limited to 64k.
So you might want to use MOD as a pivot format, and rework the whole thing. You could also export the instruments you really want, one by one, using the Instrument To WAV export, at a high frequency (such as 44100 Hz), and replace the ones from the export.
