3 Æ 1 FM: Direct Linear Frequency Modulation of Osc. 1 by Osc. 3
When an Oscillator is used as a CV source for another VCO, it is called
Frequency modulation. Frequency Modulation effects can vary from vibrato or trill
effects to clangorous inharmonic sounds to rich timbres that evoke acoustic
sounds. Linear FM is the kind of Frequency Modulation used in classic FM synths.
GLIDE:
Glide enables a glissando effect between notes. There is a switch on the left
hand controller panel that enables this effect. The knob labeled glide adjusts the
rate of glide. The glide can vary from a very fast to a very slow glide.
CONTROL INPUTS FOR THE OSCILLATOR SECTION:
There are two inputs on the back panel that accept CVs or expression pedals
that affect the oscillator section. They are labeled Pitch, and Wave. The Pitch input
controls the frequencies of all three oscillators. A one volt change of this voltage will
change the pitch by approximately one octave. The Waveform input controls the
waveforms of all three oscillators. A 5 Volt Change of this voltage will sweep the
oscillator waveforms through their entire range. Plugging in an expression pedal like
the moogerfooger EP-1 (ring = +5.5 supply to the pedal, tip =variable CV return)
produces control voltages from 0 V to +5 V at either control input.
