Offset and Scale work together. If scaling takes the velocity out of the ballpark — for example,
you want to set it to 300% but that puts all of your notes at maximum velocity — using a
negative offset, say around -60, can make it possible to still play at different volumes, although
your curve will still be a lot steeper than normal. If you use a negative scaling, then you must
use an offset: otherwise all of your velocities will end up as zeroes (well, ones actually, since a
MIDI note-on with velocity zero is something else). So to get true inverse scaling (that is, minus
100%), you must set an offset of 127 to get the full range of velocities. Setting the offset to 127
and the scale to -100% produces a slope like this (which is the same as the reverse linear curve):
Note that Offset and Scale affect only MIDI velocities; that is, these parameters don’t change
Velocity Tracking in the programs themselves. Therefore, some programs (such as organ sounds,
which often have low VelTrk values) may respond only subtly to Offset and Scale, or not at all.
