Dark EnerGy II DOEPFER Functions
For setting 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
in „learn“ mode. Bear in mind that some manufacturers count the MIDI program change numbers from 0 to
127 rather than from 1 to 128 as defined by 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 because in this case the program changes of your device range from 0 to 127 instead of 1 to
128. For some devices (especially software sequencers) the type of program change numbering
can be selected. In this case you should use the 1 to 128 range to comply with the numbers in the table
above.
The program change messages must be sent on Dark Energy II‘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 and / or CV4. If velocity is „off“, only volume (CV3) respectively the unassigned 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 unassigned controller
(CV4).
(3) Retrigger on/off
With this parameter you can select whether a new gate/trigger pulse is generated when playing legato (i.e.
playing a new key on the keyboard without releasing the key played previously). 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 way.
(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 calculate CV1 if
more than one key is being held.
• In the „last note mode“ always the last note played (chronologically) is taken as CV1. „Reference note“
means that only the reference note is accepted. This feature is useful if you want to trigger different
devices from the same MIDI channel using two or more Dark Energies. In this case you have to set the
reference keys for each Dark Energy II unit to a different value.
• „Stack note“ means that Dark Energy II will sort out the note event that is used by Dark Energy II to
generate CV1. The note event in question will not be transmitted to the (internal) MIDI Thru output of the
interface.
Stack mode is used to control more than one synthesizer via the same MIDI channel and allows polypho-
nic control of different synthesizers from the same MIDI channel.
Please note that using this mode needs the internal Link-interface of Dark Energy II which is only access
ble via an internal hardware modification. Please refer to page 25 for further information.
(7) Arpeggiator
Dark Energy II features an internal arpeggiator. An arpeggiator splits the notes of a sustained chord into a
successive pattern of single notes. In music, splitting chords into a pattern of successive pitches is gene-
rally called „arpeggio“. Dark Energy II‘s arpeggiator makes use of the following parameters:
