Two-Voice Pro QuickStart Guide

Patch Panel

Patch Panel

The modular nature of the TVS-PRO is greatly enhanced by the 56-jack patch panel located at the top of the 

front panel. This allows you to use standard 3.5 mm synthesizer patch cables to interconnect the various modules 

and functions of the Two-Voice Pro with itself — or with external devices such as analog synths, modular systems, 

and other gear — in interesting and creative ways

The patch panel contains the following signal inputs and outputs from the TVS-PRO modules:

•  Keyboard/Bendbox/Mini-Sequencer modules: 10 outputs

•  SEM A module: 10 inputs and 9 outputs

•  SEM B module: 10 inputs and 9 outputs

•  Also contained on the patch panel are two 1-in, 3-out mults

The patch panel

Even if you just use the patch panel to make connections within the Two-Voice Pro itself you can create many inter-

esting sounds. You won’t break anything by making “wrong” connections here, so experiment! 

Here are a few suggestions for patch connections:

•  Connect 

WHEEL OUT

 to VCF 

CV IN

 to control filter cutoff with the Mod Wheel.

•  Connect 

S/H OUT 

to VCF 

CV IN

 to control filter cutoff with sample & hold. Sample & hold start and rate are controlled by 

the sequencer clock, so press 

RUN

 and turn the 

CLOCK

 knob to set the rate.

•  Connect 

PULSE OUT

 from VCO 1 to VCF 

CV IN 

to perform audio-rate modulation of the filter.

•  Connect 

PULSE OUT

 from VCO 1 to VCO 2 

CV IN

 to perform frequency modulation (FM) of oscillator 2.

•  Connect LFO OUT to VCA 

CONTROL IN

 to create a tremolo effect. Rate is controlled with the LFO knob.
