Soundfont are actually embedded wave-files, so in that context you get the same effect from pitching a soundfont as you do with a wave-file, and that is wrong speed!
I need some help with pitch bending using a soundfont
Because of that pitching soundfonts cant really be done sanely, however used as an effect, you can use automation of PITCH-dial on the SF2-Player
Remember that with a higher RANGE you get significant more change in pitch over the same automation.
If this is unclear, let me know, i can make a video for you.
