Hi,
The fellow in your YouTube link is Mike Mixon and his videos are great! I have been following him for the past couple of years now and have learned so much. including so many new songs.
In many of his early videos he was saving all his songs to the Music Finder; but more recently he basically creates a registration for each song he is playing and makes changes to his OTS settings this way. His videos are very instructive - he shows you exactly how to do it. And he answers emails as well!
I got the idea of creating a sound registration from one of his videos.
Right now I have just one registration bank of my favourite 8 sounds; but for a while now it has been on my to do list to create other "sound" banks - as you suggest - I would like to have a "country" sound bank, and a "ballad" sound bank, and a "big band, sound bank. a "pop" sound bank, etc.
Hope this helps,
Mark
