No problem
maarkr, it's ok asking questions in forum (that's why it exist). And I can understand your desire to learn everything as quick as possible
What I was saying in regard of styles, registrations, OTS, etc. is, that there are always exceptions.. because there are many possibilities of how to approach/solve the problem.
Speaking for me, registrations was the last thing that I paid an attention.. because in my opinion, one should learn and understand styles first. Once you really know how styles and OTS (which is part of style) work, then you'll able to use registrations more wisely.
I noticed that many start with registrations (because "it's so simple") without really knowing what's happening underneath.. and after a while they realize they have quite a mess.
..You're saying if I want to add ie, a new voice to main variation A for use in a different registration, I should save the style as a new style, edit it and load that into a later reg memory?...
No, that's not what I was saying. I said that you need to make a copy of the style if you wish to modify note velocities of particular voice... Let me try to explain. Every voice (drum, piano, trumpet, etc.) can be louder or more strong (aggressive) -and these two characteristics are not the same thing!
You can make some voice louder by simply increasing the volume of that track. But that way you won't make it "stronger" -to make it sound stronger, you need to press key harder (faster actually). That speed of key pressing is called velocity. Yes, if you press keys harder you also usually increase volume as well. But not only that, you also change how voice sounds. For example, a string on guitar doesn't only sound louder if you smash it -it also sound differently: it sounds "stronger".
To summarize, it depends on what you wish to achieve.
