Noise Generator


miniMO's Noise Generator is a voltage-controlled digital noise generator, with the ability to alter its frequency output, grain density, and amplitude (more details here).

FEATURES

  • Pseudorandom noise generator with 32-bit long pattern
  • Real time control of  frequency or grain density
  • External modulation of frequency, density, and volume
  • Automatic Battery check

MANUAL

I/O
  1&2: Output noise/grains
  3: Input - frequency/grain density modulation
  4: Input - amplitude modulation (if frequency is selected)/amplitude and density modulation (if density is selected)
 
OPERATION
  Knob: change frequency (default) or grain density
    -miniMO waits until you reach the value it has currently stored
  Click: toggle between frequency and density control
    -The LED blinks once -  frequency control
    -The LED blinks twice - density control
        
BATTERY CHECK
  When you switch the module ON,
    -If the LED blinks once, the battery is OK
    -If the LED blinks fast several times, the battery is running low

NOTES&TROUBLESHOOTING
  Amplitude modulation also affects grain density. This is particularly noticeable when density is set to very low values
  If a parameter doesn't respond to the knob when input 3 is connected to an external input, disconnect the input, move the knob until the synth becomes responsive, and reconnect the input again
