The frequency of each channel is treated like a note in a scale, and the six bands form a chord. Spin the Rotate knob and the \"notes\" circle around the scale, rotating back to the bottom once they've reached the top. Adjust Spread and the distance between each note changes. Triggers for up\/down motion, CV inputs for sequencing, and scale selection allow for flexible control with external modules.

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. \u003cbr\u003e\u003cbr\u003e 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 ﾓrubberyﾔ 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. \u003cbr\u003e\u003cbr\u003e But the Borg is no one-trick pony, and LPGs are not for every patch.

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.

The maximum sweep range is about 8 octaves, and the PITCH CV INPUT does not track conventional solid-state VCO or filter responses (it is approximately linear or Hz\/v except in the lowest octave, and V\/oct CV will not give accurate pitch tracking). If tracking of other VCOs or v\/oct is requires, an RK4 can be forced to track a conventional VCO over a small range by feeding a \"hot\" VCO signal into the CV input.

The FLTR and DRV sections can be used independently or together to produce a wide variety of tone-shaping, from subtle distress to full-on acid destruction. The INs and OUTs of the FLTR and DRV sections are cross-normalled, so you can run your signal through FLTR and into DRV or vice-versa with no extra patching.\u003c\/p\u003e\n\u003cp\u003eFLTR is a band-pass filter with self-oscillating resonance and three feedback flavors. It is calibrated to have a vocal range that evokes vintage wah voicings. The FLAVOR switch controls the type and amount of FLTR’s resonance clipping. In Flavor 1 (down position) provides heavily asymmetric silicon diode and LED clipping, allowing your signal to remain musical and organic sounding. FLAVOR 2 (up position) adds more resonance and grit using Zener Diode clipping, but still keeps your original signal intact. FLAVOR 3 (middle) pulls out all the stops (and clipping diodes) and overtakes the incoming signal with intense resonance and filter saturation.\u003c\/p\u003e\n\u003cp\u003eOur DRV circuit is based very loosely on Tube Screamer designs of old, but it has been painstakingly re-voiced to compliment a wider frequency range and higher levels of gain.

In position 1 (down) you have the stock TS setting, with\u003cbr\u003esome low frequencies removed, but still a lot of chunk. Position 2 (up) lets the bass through, while position 3 (middle) cuts lows even more accentuating the zipper-like overtones of the incoming signal. In addition to the three HPF modes, the DRV section features three FLAVOR modes. FLAVOR 1 (down) uses symmetrical silicon diodes to a compressed and\u003cbr\u003escooped tone with lots of fuzzy gain.

Furthermore, a ring modulator and switchable VCA saturation were implemented. The VM-1 Mk2 can produce crystal-clear to wonderfully creaky sounds.

In total, eight waveforms are available. Besides standards, the VM-1 Mk2 offers triangle, saw and pulse waves that can be deformed via a potentiometer. – Cwejman fans may know this concept from the VCO-6 already. A switch for choosing pulse waveforms with mostly odd or even harmonics was implemented as well. Alternatively, noise can be used as the module’s audio source. The pitch is alterable via coarse and fine tune knobs. The oscillator’s frequency range goes from 10 Hz to 22 kHz. PWM and two 1 \/ v per octave FM inputs with attenuators can be used to control the VCO externally. Furthermore, there is a sync connector.\u003c\/p\u003e\n\u003cp\u003eSignals generated by the VCO or noise source can be mixed or ring modulated with external audio material. Results are fed to the multimode filter. Using a potentiometer, you can morph between low-pass, band-pass and high-pass characteristics. The cutoff frequency is manually controllable plus there are two CV inputs with bipolar attenuators. Alternatively to external control voltages, the modulation channels can be fed by internal sources. In detail, the first CV input may be wired to the AR envelope or the VCO. The second modulation channel is normalized to the ADSR envelope. The frequency range of the multimode filters goes from 16 Hz to 16 kHz. High settings of the resonance potentiometer make the circuit self-oscillate.\u003c\/p\u003e\n\u003cp\u003eThe VCA can be controlled via either the AR or ADSR envelope.
