Topic: Why not more DDS frequencies - especially between 32.0 and 44.1?

I love my FireFace 800, and DDS is a great feature, but the musical interval between the 32 and 44.1 frequency settings is huge -- close to a 4th.  Neither the 44.056 setting nor the coarse and fine adjustments come close to filling the gap.  Why are there no other selectable frequencies between these two?

I wanted to do a vari-speed vocal part, with a slightly sped-up effect -- a male doing a female part.  But when I recorded the part at 33.413 (32.000 with coarse and fine both cranked) and played it back at 44.1 (the setting I must use for all my projects), the difference was too extreme.  The resulting track had the "chipmunk" effect.

Any chance more selectable frequencies will be added?  Better still would be if there were a field where I could type in the exact value I wanted.

Thanks,
DM
