You'll find a call to exp2ap() with a complicated sum as
the argument. One of the terms of that sum, usually near
the end, is a constant. Adding 0.75f to that should
transpose verything from middle C to A (440) - 3/4 octave
up.

Also please check that all FP constants are single
precision as well as all math.h functions. I was
rather careless with that when I wrote those plugins.
It matters, in particular if you compile for 32-bit
SSE.
