In the the second version of the Dark Energy I we added internal buffers to the main VCO capacitor (pin 4 of the CEM3394) and to the main VCF capacitor (pin 15 of the CEM3394) to have available at least the triangle of the VCO and the VCF signal available for further processing. The idea was at this time to expand the Dark Energy by another unit (Dark Matter) that should include waveform processors/multipliers, another filter (12dB multimode), ring modulator, S&H, a second VCO, a second envelope generator, a BBD unit and so on. But then the CEM3394 ran out and we had to cancel this idea. Instead of this the Dark Energy II was designed. The technical document of the Dark Energy I mentions JP13 as "only available from version 2 of the voice board (recognizable at the silk screen printing V2 2010)": right pin of JP13 = VCO triangle output (buffered) center pin of JP13 = GND left pin of JP13 = VCF output (buffered) If sockets are connected to these terminals I'd recommend 1k serial resistors to protect the buffers against short circuits.
