Dark EnerGy DOEPFER Functionality
For the setting of these parameters MIDI Program Change messages coming from your MIDI device are
used. Normally you will have to press the program change keys on your MIDI keyboard or MIDI synthesizer
while beeing in the learn mode. Pay attention that some manufacturers count the MIDI program change
numbers from 0....127 rather than 1...128 as usual and defined in the MIDI standard. If the lowest program
change number you can send with your MIDI device is 0 (zero) you have to subtract 1 from the program
change numbers in the table above as in this case the program changes of your device range from 0...127
instead of 1...128. For some devices (especially software sequencers) the type of program change numbe-
ring can be selected. In this case you should use the 1...128 range to agree with the numbers in the table
above.
The program change messages must be sent on Dark Energy‘s MIDI channel (please refer to section „MIDI
channel selection / learn mode“ on page 19).
(2) Velocity on/off
These program change messages are used to select whether the note on velocity affects the control volta-
ges CV3 resp. CV4. If velocity is „off“ only volume (CV3) resp. the free chosen controller (CV4) is used to
generate the control voltage. If velocity is „on“ the volume or controller value is multiplied with the note on
velocity, i.e. the CV value changes with every new note event as the velocity of the note event is used to
calculate the control voltage together the volume message (CV3) resp. the free controller (CV4).
(3) Retrigger on/off
With this parameter you may select whether a new gate/trigger pulse is generated when playing legato (i.e.
playing a new note on the keyboard while the key of the former note is still pressed). The factory default
setting is retrigger off. Additionally the MIDI controllers legato (controller #68) and sustain (controller #64)
affect the gate output in the usual manner.
(6) CV1 Key Assign Mode (Note Priority)
These program change messages adjust the type of assign modes for CV1. If highest note is selected the
highest key pressed on the MIDI keyboard is used to calculated CV1 if more than one key is pressed down.
In the last note mode always the last note (chronological) is taken for CV1. Reference note means that only
the reference note is accepted. This feature is useful if you want to trigger different devices on the same
MIDI channel using two or more Dark Energy. In this case you have to set the reference notes for Dark
Energy‘s to different values.
Stack note means that Dark Energy is filtering out the note event that is used by Dark Energy to generate
CV1. The note event in question is not transmitted to the (internal) MIDI Thru output of the interface. Stack
mode is used to control more than one synthesizers on one MIDI channel and enables polyphonic control
of different synthesizers on the same MIDI channel.
Please note that using this mode needs the internal Link-interface of Dark Energy. It is only accessable via
an internal hardware modification. please refer to page 25 for further infos.
(7) Arpeggiator
Dark Energy offers an internal arpeggiator. An arpeggiator splits the notes of a played chord into a suc-
cessive pattern of single notes. In music, the split of chords into a pattern of successive notes is in general
named „arpeggio“.
Dark Energy‘s Arpeggiator uses the following parameters:
• Tempo of the arpeggio can be determined by Dark Energy itself or synced to an external MIDI device.
• Direction is defined like this: The notes are played back in the same order, they have been played on the
keyboard.
