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.
