description / manual


1 to 3 multiple with one inverted output. The multiple is normalised to the swap unit of the module.

The LFO provides a triangle and square wave and can be reset by an external gate or clock signal. The LFO signal can be attenuated with the slider pot and its rate may be varied with the RATE potentiometer. An inverted copy of the triangle wave is normalised to channel A1. An inverted copy of the square wave is normalised to channel B1. These connections are independent from the LFO attenuator and may be interrupted by patching a cable into the channel A1 or B1 input or by the normalisation selection switches. You can choose to normalise the LFO or a fixed voltage of 0V to +5V adjustable with the VOLTAGE knob for all channels at once.

WORKBENCH has four channels A1, A2 and B1 and B2. Any signal (audio or CV) patched into the inputs are attenuated by the slider pots. The channels of each section are daisy-chained, thus they can be mixed or the second channel can act as an offset (CV). The normalisation switch selects which voltage will be fed into the input if no cable is being patched (LFO or fixed voltage 0V to +5V).

The Fader mixes between two sources with a single slider. Both channel sections A and B are mixed into a fader circuit, if no cable is inserted into their outputs and the fader inputs. The fader output can be attenuated with the LVL knob.

The Swap unit exchanges the destination of one or two sources with the push of a button. This way you can route two signals to the corresponding destination of the other input. Anything patched into the Mult will also be multiplied to the Swap inputs of nothing is patched here.

USB Power
WORKBENCH is powered by standard USB power (+5V) and is fully compatible with your Eurorack system. You can choose to power it with a Mini B, Micro B or Type C USB cable. You can solder all USB connect or just one of them, if you have a favourite USB cable you want to use.
