Hi Caroline,
Please note that Jørgen Sørensen's "MIDI Mega Voice Cleaner" program is only available for PC (Windows), so not for Mac computers. In addition, "Java Runtime Environment" (JRE), at least version 8, must be installed on the PC (see the notes on the relevant product page).
By the way, another option would be to edit the style or the MIDI file in a suitable program and delete the MegaVoice effect note events on the relevant MIDI channel(s). These are the notes higher than B5, i.e. starting from C6. You could do this with "MixMaster", for example:

DAW (e.g. Cakewalk by Bandlab).
In contrast, to edit a STYLE in a DAW you would either have to load the style into MixMaster first and then forward it to Cakewalk via the "Go To" function, or you could also use Jørgen Sørensen's "Style Split and Splice" program. (Because if a style is opened directly in a DAW, edited there and saved again, the style would no longer work properly on the keyboard later.)
Best regards,
Chris
