I have already exported the session from about 200 G-70 roland styles.
By default I like to use the G-70 format because is more GM/GS compatible format and have the 18 patterns available (Qranger now can handle up to 32 patterns)
In other EMC format brand, the pattern are more less and also EMC can not match the right program change for the G-70 format.

A lot of styles are 1-1 compatible with the Sampler soundbank: import style, play style for test and export the session, need about 20 second of work.
In a lot of G-70 styles I get a Bass track problem: G-70 use the program change 120..?? and the midi track is also full of strange more notes.
i think this G-70sounds is a special version, with more layer and for this I can not configure on the sequencer ( the best way I think is to clone this sounds too under GIG format OR asking a new more compatible EMC convesrion map)

Anyway, do don't think to use the EMC style converter for the all brands styles, I found there a lot of bugs too.
When one style exported to SEQ format is not working, I have to quit the application, run again and try to export the same style, untill is working ( normally after 6-8 times the EMC will export correct)
