When using the above feature, does p{-,100} mean 100% of the normal volume for piano and f{-,75%} mean 75% of the normal volume of forte?
Thanking all in advance!
No. The numbers are absolute, with the maximum being 127 (full volume or velocity) and the minimum (in midi) being 0. However, note that 0 has a special meaning in NWC, so in practise the minimum volume or velocity is 1.
