Justanoldmuso - Thanks for your suggestion, also for a broad smile because "rig" is far too ambitious a term to use! I have BIAB on my do-everything PC. I noodle around writing music/songs based initially on chord progression snatches. I chop and change that until it gives me a warm feeling. That then generates its own melody line/variation, by which point the emotional colours may well have started to make some lyrics come floating by. Then I (agonise over) create a full perfect lyric because anything less is complete failure. Well, it all helps pass the time smile

I'll certainly check out your tips, I'm sure there'll be things from which I can benefit.
