Hello Don,
Thanks for the link, i think it will help me further.
As i've read from the PCR500 manual is that you can only save 2o usermaps, which can contain all the tones/settings you need for one or more songs, after you've configures them via the PCR EDITOR V2 on your laptop. As for now that will be enough. But when your doing a live performance with the band i think i might need more, but im not sure yet. i have to gather all the orchestrations of the songs first and organize the controlmaps in an efficent way. I tink you're right about the usb port on the bk-7m; its purpose, besides for backup and storage of a performance, is unusable for what i had in mind.
Thanks again for the link.
regards, herman
