Oset 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
oset, say around -60, can make it possible to still play at dierent volumes, although your curve
will still be a lot steeper than normal. If you use a negative scaling, then you must use an oset:
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 oset of 127 to get the full range of velocities. Setting the oset to 127 and the scale to
-100% produces a slope like this (which is the same as the reverse linear curve):
Note that Oset and Scale aect 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 Oset and Scale, or not at all.
