Yeah, I think I will need to write a patch editor after all.  The reflection lowpass
filter parameters are stored in a ROM to supply individual numbers for each waveguide.
 The higher notes tend to be plinky sounding and need the parameter adjusted for more
high frequencies.  The values in the ROM are rough guesses, but I think the instrument
would benefit from being able to easily hand adjust them.
