3.3.2. MIDI to CV/Gate interface

The „USB/MIDI-to-CV/Gate" interface generates not only a pitch control voltage and a gate signal to trigger

the envelope with, it also produces several control voltages derived from incoming MIDI velocity and MIDI

controller data. The MIDI-to-CV interface also features a simple but useful arpeggiator and a so-called

reference pitch. You have encountered the reference tone before when you selected the MIDI channel -

it was the MIDI note that set Dark Link's pitch CV1 to 0 Volts and thus became the lowest key of Dark Link's

resp. of the connected CV/gate synthesizer's key range.

All CVs and the gate signal can be tapped from sockets on the front of Dark Link. Use patch cords or

adapter cords to connect them with the suitable inputs on your CV/gate controlled synthesizer. In case,

your synthesizer is equipped with the suitable inputs, you can control it's most important sound parameters

dynamically via MIDI velocity and a MIDI controller.

Depending on the incoming MIDI data (note on/off, notenumber, pitch bend, MIDI controller, velocity), the

interface will generate:

• The gate signal for the envelope generator: The level of the gate-signal (5V or 12V) as well as

switch trigger (needed for some vintage Moog and Korg synthesizers) can be selected via an

internal jumper on the board of Dark Link. Default setting is +5V. Please refer to page 15/16.

Polarity can be inverted via learn-function. More on this on page 12, note (4).

• CV1: controlled by MIDI note numbers;

1V/oct scaling

Range: 0...+5V

• CV2: controlled by MIDI pitch bend data (ranges approx. –2.5V to +2.5V or 0V to +5V,

selectable via internal jumper). Default setting is –2,5V to +2,5V. Please refer to page 15/16.

• CV3: controlled by volume or the sum of volume and velocity (selectable via learn mode).

Please refer to page 11, note (2).

Range: 0...+5V.

• CV4: controlled by a freely selectable MIDI controller or the product of controller data and

velocity (controller number selectable via learn mode).

Please refer to page 11, note (2).

Range: 0...+5V.
