The top item lets you select the output you want to edit.
The centre item lets you set the 'centre' CV, which will be 0V if the output range is set to ±5V. It 
corresponds to MIDI note 60 (C4).
The lower item lets you set the '+3 octaves' CV, which should output 3V more than the centre CV, 
or in terms of pitch, a note 3 octaves higher. It corresponds to MIDI note 96.
The output is set to the value you're editing as soon as you move the cursor over it.

Reset Settings

This menu allows you to reset the settings to default values.

Miscellaneous

The top level menu item 'Misc' provides access to some miscellaneous functions that don't fit 
anywhere else.

Misc menu item

Function

Show firmware version

Displays the current firmware version.

Reboot

Causes the module to reboot.

Show MIDI history

Continuously shows the last four MIDI messages received.

Test inputs

Enters a mode which displays an oscilloscope-like view of the inputs. 
Intended for factory use only.

Test outputs

Enters a mode which generates a continuous test signal on all eight of 
the module's outputs. Intended for factory use only.

Resets

The 'Resets' menu allows you to reset certain aspects of the current preset to default values.

Reset LFOs

Resets all LFOs to defaults:

•

Multiplier to maximum (16383).

•

Waveform levels to zero, except saw, which is set to 64 (off).

•

Pulse width to 64 (50%).

•

Tempo Base to 24 and Tempo Mult to 1.

•

Speed to zero, and the LFO rate is set as Hz.

Reset MIDI/CV

Resets all MIDI/CV converters to their initial state.
