Generator
(Dual Oscillator FM Monster)
[No Longer In Production]
A dual oscillator built around two triangle core, wide range, periodic waveform generators. As a multipurpose signal generator, it can provide the basis of a wide range of complex sounds ideal for tuned percussion/noise, abrasive amplitude, frequency and timbral modulation. Tones, drones, textures, and drums to atonal, nintendo zipper/fart noises. This module was made for FM madness.
Size: 10hp
Depth: 35mm
Power Usage: 30mA
Generator Controls Description
Generator Controls Are Divided Into 5 Rows
GEN1 - Control Set For Generator 1 (Oscillator 1)
EXP - An exponential CV input to control the rate of Generator 1. Although it is an exponential response, the Generator does not track 1 volt per octave and is not temperature compensated.
3 WAY RANGE SWITCH - a coarse adjustment for the Generator 1 frequency. Left = Low, Center = High, Right = Mid
RANGE POT - The fine adjustment for Generator 1 frequency.
EXTERNAL - FM modulation Input
INPUT ATTENUVERTER for the CV input. Pot zeros out at 12 o'clock.
DESTINATION SWITCH - Determines which Generator (1 or 2) is modulated. Up modulates Generator 1, down modulates Generator 2.
EXTERNAL INPUT - Accepts CV and audio rate signals as a modulation source.
GEN2 - Control Set For Generator 2 (Oscillator 2)
*Generator 2 is exactly the same as Generator 1 EXCEPT... Generator 2 is FM'd internally by the Generator 1 Index Out, which means the amount of internal FM of Generator 2 is controlled by the Index Pot and/or Index CV input.
EXP - An exponential CV input to control the rate of Generator 2. Although it is an exponential response, the Generator does not track 1 volt per octave and is not temperature compensated.
3 WAY RANGE SWITCH - a coarse adjustment for the Generator 2 frequency. Left = Low, Center = High, Right = Mid
RANGE POT - The fine adjustment for Generator 2 frequency.
SHAPE - Generator 1 & 2 Waveform Controls
SHAPE POT - Controls the waveforms of both Generator 1 and Generator 2. Turned full left, Generator 1 is a square wave and Generator 2 is a triangle wave. Turned full right, Generator 1 is a triangle wave and Generator 2 is a square wave
1 - Output for Generator 1 (Pre Index VCA)
2 - Output for Generator 2
INDEX (Generator 1 VCA Output Control)
CV INPUT for the index VCA
OUT - Post Index VCA Generator 1 output.
INDEX POT - Gain control for Generator 1 Index VCA. The Index Pot is not an attenuator for the Index CV input. Full left is 100% gain. Full right is 0% gain. Turn the Index pot full right to get the full effect of the CV input on the signal. Turn the Index Pot full left to get 100% regardless of CV input.
Patch Example
A good start for percussion...
- Patch the output of Generator 2 (2) into the External CV Input and set the External Switch to the up position to modulate Generator 1.
- Patch an envelope generator into the Index CV.
- Listen to the Index Out.
- If you set the Generator 1 Range Switch to the low position and the Generator 2 Range Switch to the mid position and adjust the fine frequencies, you get a nice percussion sound.
The Generator circuit was designed by Thomas O’Connor.
