In most places I think we use the Shift or sometimes Alt key for a variation. Possibly a more user friendly answer might be when initiating a learn, for a single incoming controller to generate a pair of learn lines with slightly different text lines. e.g. Part 1 Kit 1 AddSynth Amp Env Point 4 amp Part 1 Kit 1 AddSynth Amp Env Point 4 time That sort of wording would ensure they stay together, and the user can later independently alter the min/max amounts. Just before reaching the Min.Max controls all incoming values will have been converted to 0-127 floats and after these are currently then expanded to the actual required range. Time is a difficult one. We'd need some form of ranging adjustment as it could be mS or Seconds. Possibly, Min and Max could be redefined as multiplier and value. Whatever the choice the wording has to be user friendly - start using words like 'delta' and we'll lose many of them. P.S. You definitely don't pick the easy ones do you :) -- Will J Godfrey _______________________________________________ Yoshimi-devel mailing list Yoshimi-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/yoshimi-devel
