To convert from Tyros to 3K:
Select PSR-3000 in the Target Instrument box
Click on Select files to add files for processing . You can use CTRL Right Click to select multiple files.
Click on Process Save and select an existing folder as a place to put the processed files.
That is all you need.
Let me know (mpb@sover.net) if you have any questions.
