    Here it is. Can you look at the lfoRate() method. I've assumed 100 COUNTS_PER_LFO is 6Hz and used that as the basis for converting LFO rate in Hz to countsPerLfo. This probably isn't correct but it's...

    I've added a method to alter COUNTS_PER_LFO and it gives a nice lfo rate effect, ranging from 500 to 50 exponentially.
