Q106  

Oscillator

 

 

Jun 2014 

The Q106 Oscillator is the foundation of any synthesizer providing the basic 
waveforms used to construct sounds.  With a total range of .05hz to 20kHz+, 
the Q106 operates as a powerful audio oscillator and a full-featured LFO. 
 
The frequency (pitch) of the oscillator is controlled manually, by voltages 
from other modules, and by voltages from controllers such as keyboards. 
Both linear and standard 1-volt-per-octave exponential voltage inputs are 
provided - each scalable by panel controls. 
 
Five waveforms are available simultaneously - Sine, Triangle, Sawtooth, 
Ramp and Pulse.  The Pulse waveform is adjustable manually and may be 
modulated via external voltage control. 
 
A Hard-Sync input allows synchronization between oscillators. 
 

Controls and Connectors 

 
     There are 6 sections (listed top to bottom) 
     - Frequency Range Section 
     - Hard Sync Section 
     - Linear Frequency Control Section 
     - Pulse Width Control Section 
     - Exponential Frequency Control Section 
     - Output Section 
 
     Frequency Range Section 
     Frequency Range Control  
          Selects octaves from 32hz to 512hz with a 'low' setting for 
          modulations.  
     Frequency Control  
          Allows fine control of pitch over 1 octave.  
 
     Hard Sync Section 
     Hard Sync Connector  
          Allows the oscillator to be syncronized with other oscillators to 
          prevent beating and to create strange effects.  
 
     Linear Frequency Control Section 
     Linear Frequency Control Connector  
          Allows external control of pitch with a linear response.  
     Linear Frequency Level Control  
          Determines the amount of affect that the linear control voltage has 
          upon pitch.
