Hi rharv, and thanks for following up.
I guess I could get things lined up by working in audio, but then of course my MIDI-type editing capability is lost. My inclination would probably be to continue with MIDI and edit manually using my ear to guide me (forgoing quantizing routines, for example), and be very careful lining up copy/paste functions.
And while I'm about it, it's time to express my appreciation to you and all the others on this forum who reply to the huge range of queries from befuddled users like myself - bless you all!
On account of having just now downloaded Sampletank and seeing on the forum that more savvy people than me seem to have issues getting it to work nicely with RB, I've got a feeling I'll be back with lots of questions before too long!
Clinton.
