malekko heavy industry richter dual borg filter price : $325.00

the malekko richter series in eurorack modular format, offer the same great sound, ergonomics, musicality, and quality that made the wiard 300 series legendary, at a fraction of the cost and size.

the dual borg contains one borg i (left side) and one borg ii (right side). the borg is a versatile audio processor. the concept comes from a marriage of two divergent influences, the buchla 292 low pass gate and the korg ms20 filter.

the borg is different from most filters in that, at its heart, is a vactrol. vactrols are combination light sensor/light resistors that possess interesting sonic traits. often described as "rubbery" or smooth in quailty, vactrols are also know for their relatively slow response. this response creates a natural, very musical decay. in low pass gate (lpg) mode, the borg will act as a filter and a vca simultaneously. in combination with the characteristic vactrol response, this creates a signature sound that is desired by many synth enthusiasts, especially when used with very short, percussive patches.

but the borg is no one-trick pony, and lpgs are not for every patch. when the resonance knob is turned "on" with a click, the borg becomes a 12db filter with loads of personality. gorgeous resonance, influenced by the ms20 and shaped by the vactrol design swells from subtle warmth, to a roaring howl that is unique to the borg!

a continuously adjustable low pass to high pass control is provided (a notch filter is a mix of these two). there are two audio inputs, and two cv frequency inputs (one with attenuation). two outputs are provided, output 2 has a slightly more aggressive resonance. removing a jumper on the back of the borg makes the resonance "scream" even more!

the borg i (left side) has a slower response and a more mellow sound compared to the borg ii (right side). thanks to its longer decay time, the borg i is best for recreating the famous buchla bongo patch, and the borg ii is best for a faster, more aggressive response.

the signal path of the dual borg is selectable: series or parallel.

in series mode, when you plug into either in 1, or in 2, or even both inputs (as a mix), the signal is routed through the borg i then the borg ii filter and both out 1 and out 2 have the same signal.

in parallel mode, a single input into in 1 or in 2 is routed through both filters side by side, and a single output (either out 1 or out 2) will give you a mix of both filters. if you have only one input but two outputs, out 1 is the borg i filter only and out 2 is borg ii only. if you have two inputs and two outputs, then each filter is completely separate: in 1 and out 1 is borg i, in 2 and out 2 is borg ii.

the borg is 16hp wide, 25mm deep, and consumes approximately 80ma power.
