3.3.2. MIDI to CV/Gate interface

Since Dark Energy II‘s sound generation works entirely analog, and „real“ analog control voltages and gate

signals are used internally, the unit features a complete USB/MIDI-to-CV/Gate interface.

This integrated „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 ve-

locity 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 Energy II‘s pitch CV1 to 0 Volts and thus became the lowest

key of Dark Energy II‘s key range.

All CVs and gate signals can be tapped from sockets on the back of Dark Energy II. Use patch cords to

connect them with the module inputs on Dark Energy II‘s frontpanel. This way you can control the 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:

frontpanel as desired.

control inputs on Dark Energy II‘s frontpanel as desired. Please refer to page 20, section (2).

By changing an internal jumper, the CV4 socket can become a second audio output. In this case, CV4 is

not available anymore. This mod allows you to use Dark Energy II without any cable plugged into the front-

panel. The default setting is CV4.
