because it is now used as the 'bump' mode coefficient more often than it's original
intent as a threshold offset in the spec. dist. envelope following modes.

The phasor value must be limited to a max value - the size of the wave table
otherwise the resolution of the phasor object phase counter eventually
diminishes due to the increasing value of the integer part of the
floating point value.  This will result in distortion in the wave table
output because the phase value will not increment reliably.
