Controls

1. Signal Frequency
   Frequency range is selectable with a jumper on the PCB.


2. Controls the shape of the signal.
   Fully clockwise is completely random, anti clockwise is controlled by the mode switch.


3. Attenuverters for the rate and change CVs


4. Mode switch
   Selects the anti clockwise shape.
   Up: Random walk
   Down: Repeating 8-step sequence


5. Signal and gate LED


6. CV Inputs for rate and change control(+/-5V)


7. Gate output
   A gate signal is generated whenever the CV out reaches its middle value


8. CV output selectable via jumper between 0 to 10V and -5 to +5V

Firmware update

The firmware can be updated by playing back a special audio file to the CHANGE CV in jack.

To update the firmware:

• Download the current firmware image here malaclypseJr_v1.0.wav
• Connect an audio player to the CHANGE CV in jack
• Turn the power on
• The LED will start to flash green for a short moment
• If the switch is moved during this time, the firmware update mode is started and the flashing turns red.
• Start the playback of the firmware audio file
• The LED will change to a slow green flash while the firmware update is in progress
• When the audio file has finished the module will reboot with the new firmware.
  
• A constant red LED indicates a read error. Probably your output volume is too low.
• You can move the switch to try again.
• If the LED just goes off, your audio volume is too low, too. Amplify the signal and try again.
• Some audio players are not loud enough. In that case use an additional amplyfier/mixer between your player and the module.
