Well, that is at all really surprising.
Renaming a control takes about 30 seconds for the developer (if not he definitly had to think about a better naming system).
But this naming at all looks like you have discussed naming, and to give peace, every of the discussion partners have given a part to the naming:
One for Lead-in, lead-out, lead --?
One for greatest, smallest, average feature size
one for greatest, average, smallest scale,
well may be the one for the octave naming did loose, lowest, highest and main octave.
And so we look at different names for equal controls.
I do not know, if it really was so, but it looks so. Great teamwork and absolutley not confusing - if you have read the documentation and learn the TG2 language. So, hear to all those, who ensure, that TG2 is all easy, logical and do not change the naming before the final release and give us all a chance to learn to think and speak like a terragener. We will be part of a outstanding community and able to talk to each other by being sure, no one outside of our community will be able to follow us.
