(lfo type)_freqpolyaft

LFO frequency change when polyphonic aftertouch MIDI messages are received, in Hertz.

Can be negative, and according to the SFZ spec the allowed range is -200 to 200, which could be used to push LFO frequencies into audio frequency range, allowing AM, FM and filter growl. Perhaps that was a typo and it should be -20 to 20, as 20 Hz is the maximum LFO frequency in the SFZ 1 spec.
