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).
SOURCE CODE
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 I/O 3 is connected to an external input, disconnect the input, move the knob until the module becomes responsive, and reconnect the input again
