The Pilgrim is a free filter ideal
for both live and studio situations. It has a
high-pass and low-pass filter programmed into one
dial, and allows a seamless sweep between the two.
It works similar to the 'Pioneer DJM' mixers, albeit
with a little extra functionality: a wet/dry dial
which can also be used as a basic equaliser/shelf
filter. The frequency pass range is from 60Hz (lowpass)
to 19kHz (highpass).
