Looks good... What formats will it support? Anything that plays Roland styles directly from the computer will be handy.

Am I right in presuming the user themselves imports the styles to it, and fills in all the fields? And are those source and destination fields merely data, or do you actually envision this actually doing the conversion (a la EMC)?

Donny's question is actually a good one, as people will often rename styles. Could there be a function that examines the styles' data, and when it finds identicalness (even under different names), it groups them together? Some sort of bit comparator or checksum comparison, I guess...?

Looks promising, but I'm still hazy on what it is likely to be for...
