The glide option is available as a kit: It consists of rotary potentiometer with Dark Energy style knob and nut, 2-wire cable and 2-pin connector. All parts are assembled, no soldering required. Please contact the dealer in your country for price and delivery time.

To install the glide option the bottom cover of the Dark Energy has to be removed (four crosshead screws at the edges). The jumper installed on the pin header labelled JP4 of the interface/supply board (i.e. the board mounted to the rear panel) has to be removed. Instead of that the connector of the glide option is put on the pin header JP4. The orientation does not matter. JP4 is located behind the CV3 socket. A picture that shows the complete interface/supply board is available here: Dark_Energy_technical_information.pdf (valid for Dark Energy I) or Dark_Energy_II technical_information.pdf (valid for Dark Energy II). Then the plastic cap at the front side has to be removed and the potentiometer is mounted into the hole by means of two nuts. Finally the knob is put on the potentiometer and the bottom cover is screwed tightly again.

Important Notes: If the glide option is removed later the former jumper has to be installed to JP4 again ! Otherwise the CV connection between the interface and the VCO is interrupted and the pitch of the VCO is not controlled by the USB/Midi interface. If the VCO pitch does not respond to incoming USB/Midi data please double check if the jumper has been re-installed to JP4 !
The glide option only affects the internal CV coming from the built-in Midi/USB interface. It does not affect the CV input (socket labelled "VCO F").
