How to open the sub menu:
• Hold down the Function key for at least 5 sec. The Function LED flashes and the other three
key-LEDs light up.
• Press the Start/Stop key (it remains lighted up). You just entered the sub menu.
In this state of function, the Step switches ”On/Off/Skip” of the steps 1 - 11 work as on/off switches for
several sub-functions. Only the ”On/Off” positions are relevant (not ”Skip”).
The step LEDs show you the current status of the corresponding function. Since the setting of the switches
may not necessarily match the current function-status after entering the sub menu, it is useful to operate the
switches several times until you get a clear feedback over the current function status.
• To exit the sub menu, simply press ” Function ” once more. Dark Time reverts to it‘s usual way of
opration.
The following CV/gate output related functions are available in the sub menu:
Gate polarity ( Step switch 2):
Invert the polarity of the gate signal here. If switched to ”On”, Dark Time puts out gate signals 1 and 2 with
an inverted polarisation of 5V (12V with modification). The factory setting ist ”Off” (positive gate).
CV-output hold level ( Step switch 3):
With this function enabled, the CV level of the last played step is held, even if the next step is set to ”Off”
(Step switch = ”Off”). In the factory setting, this function is disabled.
Gate lenght normal/legato ( Step switch 4):
Usually, the pulswidth (resp. gate-lenght) of each step has a value range between 15% and 85% of the
clock rate (”normal” = factory setting). This range can be extended to 1% to 200% (”legato”). When using
settings around 1% or >100%, unpredictable, but sometimes interesting results may occur, e.g. short multi-
triggers. Please be warned...
CV Inputs:
The inputs CV 1 In and CV 2 In take external control voltages within the range of 0V and +5V. These
voltages will be added to the voltages generated by the step registers. Both registers
may be addressed separately, with CV1 In corresponding to the upper register and
CV2 In to the lower.
There are many uses for these inputs, especially in combination with a modular
synthesizer system, e.g. the Doepfer A-100. You may feed dynamic voltages into
these inputs on order to achieve portamento effects or use staircase-type voltages to
transpose the step registers automatically.
Clock connectors:
To synchronize two instruments in the analog domain – e.g. Dark Time and a non-MIDIed vintage drum
machine – a clock signal is needed. A clock signal is a pulse wave, its frequency (pulses per time) determi-
nes the tempo of the synchronized device. When active, Dark Time will generate such a clock signal and
make it available at the Clk Out socket.
Changing the gate output voltage from +5V (default) to +12V by changing an internal jumper (see page 21),
will generate a clock signal of +12V.
• Dark Time as master:
Connect Dark Time’s Clk-Out socket to the clock-in socket of the ”slave” device (e.g.
vintage drum computer or another analog sequencer). Set Dark Times
Sync
switch
to ” Internal ”. Now set up the external device as a ”slave” as described in its manual.
• Dark Time as slave:
You can also synchronize Dark Time to the tempo of an external device via the Clk In
socket. The master device must produce a suitable clock-signal (0/+5V) and has to
be connected to Dark Times Clk In socket. Set Dark Time’s Sync switch to
” MIDI/USB ”. Its internal clock will now be driven by the external clock signal instead.
