Connections

On the rear panel of Dr. Octo Rex you will find the connectors. The left part of the panel houses a number of CV/Gate inputs and outputs. Using CV/Gate is described in “Routing Audio and CV”.

Modulation Inputs

These control voltage (CV) inputs (with trim pots), allow you to modulate various Dr. Octo Rex parameters from other devices (or from the modulation outputs of the Dr. Octo Rex device itself). The following CV inputs are available:

•	Master Volume

•

Mod Wheel

•	Pitch Wheel

•	Filter Cutoff

•	Filter Resonance

•

Osc Pitch

Modulation Outputs

The Modulation outputs can be used to voltage control other devices, or other parameters in the Dr. Octo Rex device itself. The Modulation Outputs are:

•	Filter Envelope

The Filter Envelopes in Dr. Octo Rex are polyphonic (one per voice). Only the filter envelope of voice 1 is output here.

•

LFO

Gate Inputs

These inputs can receive a CV/gate signal to trigger the two envelopes. Note that connecting to these inputs will override the “normal” triggering of the envelopes. For example, if you connected an LFO CV output on another device to the Gate Amp input on the Dr. Octo Rex, the amplitude envelope would not be triggered by the incoming MIDI notes to the Dr. Octo Rex device, but by the LFO CV signal. In addition you would only hear the LFO triggering the envelope for the slices that were playing at the moment of the trigger.

•	Amp Envelope

•	Filter Envelope

Gate Output

This outputs a gate signal for each triggered slice in the loop.

Slice Outputs

To the right of the modulation inputs and outputs are the eight individual slice audio outputs. You can assign individual slices to any of these outputs as described in “Editing in the Waveform Display”.

Main Outputs

To the right are the main left and right audio outputs. When you create a new Dr. Octo Rex device, these are auto-routed to the first available channel on the audio mixer.
