EXTERNAL AUDIO IN:
The External Audio in allows an external audio source to be routed into the mixer,
where it can be mixed with the VCOs and Noise source, then passed to the filters
and the out put. The LED above the External input begins to light up as the Input
signal to overdrives the Mixer input. When the light is faint, a small amount of soft
clipping is occurring. When the LED is bright, the signal is really strongly overdriven.
Judicious use of overdrive can really fatten up a sound. The external audio input
can accept a signal from instrument level to line level.
MIX-OUT LOOP:
The jack on the back labeled “mix out/filter in” is an insert point between the
Mixer output and the filter input. Using a standard insert cable an effect such as a
moogerfooger MF-102 Ring Modulator can be inserted to add effects to the
oscillator, noise source, and external audio in prior to the filter stage. The Mixer
output signal send appears at the tip of the jack. The return signal appears at the
ring of the jack. A cable plugged into the jack breaks the connection between the
mixer and the filter, Unless the Return signal is sent to the ring of the jack, no signal
will pass through to the filter. The level settings in the mixer affect the output level, so
keep this in mind as you try different devices in this loop. This insert point is a great
spot to insert a distortion or waveshaping device, a phaser, ring modulator, or delay
effects (figure 17).
