The 2-channel LED bargraph can be used to monitor the level of the inputs and outputs.

If the display is not showing the bargraph - for example if it is showing the current function of one of the
two channels - press the 

METER

 button to bring it back.

When the bargraph is active, press the 

METER

 button to cycle between the 4 visualization modes:

Note that the arrangement of the LEDs mirrors the arrangement of the physical inputs/outputs of the
channel 1 of the module.

The module detects whether an input signal is a CV or an audio signal. When the signal is a CV, the
length of the bar is proportional to the CV level. The 4 bars are lit for a CV of 8V. The LEDs are green or
red depending on the polarity of the signal. When the signal is an audio signal the maximum level
corresponds to 16V pp, and then each LED represents a level change of 6dB, with the lower two LEDs lit
in green and the upper two lit in orange and red.

When the compressor mode is active, when monitoring the output level, the bargraph will display the
amount of gain reduction rather than the final output level.

Press channel 1 or 2’s function selection button to disable the bargraph display, and then to cycle through
the four functions.

The next section explain in details how each function operates.

In this mode, amplitude and brightness are controlled by an internal envelope generator. The envelope is
triggered by sending a trigger pulse to the 

EXCITE

 input. Properties of the trigger pulse - such as its

amplitude, duration, and slew rate are taken into account to bring variations to the envelope shape.

The 

SHAPE

 knob controls the envelope shape. Over the first half of the course of the knob, envelopes

with immediate attacks and increasingly long decay times are available. Over the second half, the attack
