MIDI Mega Voice Cleaner is a software program for converting Yamaha keyboard Mega Voices in MIDI files.
Download Page - Program Help - Technical Problems

MIDI files created at the TYROS; the PSR 3000 and the PSR S-series keyboards may use Mega Voices.
This voice type is not found at other keyboard models (or sound cards) which means that these voices do not sound right.
This program substitutes Mega Voices with the best suited standard XG voice.
Mega Voice notes higher than note B5 are omitted, as these can not be substituted properly.

NOTE:
During the years the Mega Voices have got more complex, and the number has increased dramatically.
This means that the conversion in some cases is rather problematic; and hence an individual revoicing of the style might be required.
