Umm... why not just use a lookup table for the whole darn thing??
I don't understand why you would need to generate it in realtime...
the minBLEPs are indentical for each cycle, except for maybe
inverted. There is no need to recalculate unless you are changing the
corner frequency at which harmonics begin to roll off.
