I have a number of bass soundfonts that are mapped in different octaves and this lets you compensate for it, but if I change to a different soundfont, I would have to go back in and make this change again.


Yes this can get a little confusing, especially to a beginner. Guitar and bass are written an octave higher than they sound. Some sound sources take this into consideration and do the transposition for you while others do not. Thus if you have a bass line that is written in concert pitch (no notation transposition) but your sound source expects the input to be transposed then you will have to adjust the incoming data. Same thing if visa-versa.

I hope this helps.
