3.3. USB/MIDI Interface
3.3.1. Connection / MIDI channel
Quite likely, you want to play your Dark Energy via MIDI – there are two easy ways to do so:
• MIDI via USB or
• the „classic“ MIDI-connection via DIN socket.
• USB: To hook up Dark Energy in your MIDI-setup via USB, simply connect the included USB cable to
Dark Energy and to a free USB port on your Mac or Windows PC.
Mac OSX, Windows XP (SP2 or higher) and Windows Vista provide the necessary drivers and Dark Energy
will be mounted as soon as it is connected. You will find a new MIDI port in your MIDI application, named
„USB audio device“ (Windows XP) or „Dark Energy“ (OSX, Windows Vista) and you are ready to go.
If this message is missing or an error message is shown, e.g. „USB device not found“, the necessary driver
is most likely not installed or not working properly on this computer. In this case, Dark Energy‘s USB port
unfortunately cannot be used on this specific computer. We apologize for not being able to support this pro-
blem, since there will be multiple causes, very specific and depending on the computer. Of course you can
run Dark Energy in such a case via the MIDI DIN-connection without any problem. The same goes if you
use an older Windows or Mac System that does not provide the necessary drivers.
• DIN socket: You may connect Dark Energy alternatively via MIDI cable to a MIDI interface, a MIDI key-
board or a MIDI hardware sequencer.Simply connect the MIDI output of your MIDI device to Dark Energy‘s
MIDI port. Please do not use USB and DIN connections in parallel.
• MIDI channel selection (Learn button): In order to enable Dark Energy to receive incomming MIDI data,
the MIDI channel of both the MIDI device and Dark Energy have to be identical. You may select Dark
Energy‘s MIDI channel like this:
– Select the desired MIDI channel on your MIDI device / software application. Please refer to their user
manuals.
– Press the Learn button on the back of Dark Energy and keep it pressed down for at least one second.
The LED starts flashing, showing that Dark Energy is in learn mode. The delay of one second avoids
unintended enabling of the learn mode. The flashing LED always indicates Dark Energy‘s active learn
mode. To press the learn button easily, you may use a pen or a plug.
– Press the key on your keyboard with the lowest note, that Dark Energy should be able to play. This note
will set CV1 (pitch CV) to 0 Volt. This is approx. equivalent to 65 Hz / „C“, when tuning knob and range
switch are both in centerposition. The available range covers five actaves above that note. The default
setting is MIDI note number 36.
– Done – Dark Energy‘s MIDI channel now fits to the one of the connected MIDI device. Dark Energy
disables the learn mode automatically and changes to usual running mode. If you might enable the learn
mode unintended, simply hit the learn button again to leave learn mode.
When Dark Energy receives a MIDI note, the learn LED goes off for a short moment. You may use this as a
MIDI-in indicator, without the need to connect a soundssystem.
