Sub Octave
8.
Turn up the SUB OCTAVE LEVEL dial to 12:00 and engage the SUB
OCTAVE footswitch. The red LED should come on. Play your
instrument.
Note:
Not all amplifiers can reproduce the extreme low end of the
Pigtronix Sub Octave. If you are having trouble hearing the Sub Octave in
your amp, run the SUB OUT jack to a bass rig to truly rock the house.
Ring Modulator
9.
Turn off the SUB OCTAVE footswitch.
Set the VCO wave switch to the
OFF (center) position. Turn the RING MOD LEVEL dial up to 12:00.
10.
Turn on the INTELLIGENT RING MODULATOR footswitch. The green LED
should come on.
11.
Play a single note and adjust the RING MOD TUNE dial across the full
range of its travel while repeatedly playing the same note. Listen to
the range of textures you can get from this Ring Modulator.
12.
Choose a Ring Mod sound and play your instrument. Notice how the
intervallic relationships between the tones do not change as in other
ring modulators. This is because the carrier oscillator in this Ring Mod
circuit is tracking the pitch of what you are playing.
13.
Turn on the GLIDE toggle switch. Set the RING MOD SOURCE toggle
switch to VCO and set the VCO wave switch to Square wave.
14.
Now the Ring Modulator is tracking the VCO and takes on a different
tonality. Notice that now the Glide causes the ring modulator’s notes
to travel in parallel with the VCO as the pitch bend occurs.
15.
Turn down the VCO LEVEL dial and listen to the Ring Modulator by
itself.
16.
Set the VCO WAVE switch to Triangle wave for another cool Ring
Modulator sound. Play a bit and then turn the VCO LEVEL control
back up.
17.
Now set the RING MOD SOURCE switch back to INPUT and play your
instrument. Notice how the ring modulation notes move
contrapuntally with the VCO as the pitch glide takes place.
18.
Turn up the CLEAN SIGNAL LEVEL dial and listen to the Ring Modulator
mixed with the VCO and input signal. Turn on the Sub Octave to hear
all the voices together.
