Come on, can we get a dedicated section to upload our creative ideas to share with others? This isn't rocket science and would help those of us without masters degrees in electronic engineering.
Yamaha has indicated there is a version of Soundmondo for Montage in the works. This would be the best "official" method. Otherwise, other users have attempted gap-fill measures for the non-official route. One is an off-site web. Another is a thread.
If uploading - the best format is X7B (bulk save) and remember to zip the file before adding as an attachment.
Current Yamaha Synthesizers: Montage Classic 7, Motif XF6, S90XS, MO6, EX5R
