I'm sorry if this has been brought up before, but I find the range limit colouring to be a bit misleading in male voices.
I only use MS for male choir music, so I don't know whether this problem extends to the other voices.
The main problem is that the ranges are too narrow, both upwards and downwards, both for tenor and bass. It's not much - perhaps only a note or three, but it is a bit confusing when I see a note I (a bass) can sing comfortably, which MS tells me is uncomfortable or impossible for a professional (the C in the attached file).
The other problem is that there is only one instance where there is an "amateur" range limit, i. e. the high tenor limit. All other limits go directly to "professional".
Will this issue be addressed, or, preferrably, will we be able to determine custom ranges for voices in future releases?
