The MX-4S is a voltage controlled stereo mixer with four independent inputs. All parameters such as input gain, panning and output again ( both left and right channels output level are ganged) are controlled manually by knobs or associated CV inputs. The mixer accept both DC and audio signals so it can be used for audio signals and control signals. The LED bars displays the outgoing signals strength. The performances of the mixer such as low distortion and low noise, are superior thanks to ” the state of the art” voltage controlled devices.

The DMF-2 is a dual mode and dual slope filter and emulates the familiar low pass filter in 4 pole mode and expands sonic potential by adding a unique designed 6 pole low pass mode and quasi and pass mode.
Both filters (A and B) are identical and can be controlled separately and by master inputs for the cutoff (CM A+B). The audio outputs from both filters are combined (LPF A+B and BPF A+B) with dual resonance (peak and offers “formant” shaped sounds in low pass and band pass mode. Filters has an individual audio inputs and additionally combined input (AUDIO A+B).
The DMF-2 is characterized by a non-linear transfer function, so-called saturation mode, that is affected by the level strength of the incoming signals.
The design quality of LPF’s and new features makes the DMF-2 very flexible and results in qualities, such as:
*CUTOFF, Q-PEAK are voltage controlled
*4 and 6 poles low pass mode (24 dB/octave and 36 dB/octave)
*Qasi band pass mode (6dB/octave high pass on the low side and 24dB/octave low pass on the high side)
*Saturable; from “warm” and “smooth” sound (at low to moderate level of incoming signal) to heavy distorted “nasty” and “aggressive” (at high level of incoming signals)
*Ideal as “effect filter”
*Formant mode (dual peak) with summed inputs and outputs
*Stereo effects
*Low noise
Both envelope generators are identical and provide control voltages that can be used for dynamic change of all voltage controlled parameters, such as; frequency, amplitude, pulse width, cutoff.
The most common use is controlling a filters cutoff frequency and a voltage controlled amplifiers amplitude in order to achieve dynamic timbre- and level-changes. All parameters such as attack time, decay time, sustain level, release time and output level are voltage controlled.
RES-4, four band voltage controlled parametric resonator
The RES-4 is a four band pass filters in to two outputs; BAND PASS and NOTCH. The BAND PASS is a sum of all four filters (RES1, RES2, RES3 and RES4) in phase and the NOTCH is a sum of filter1 (RES1) + fiter3 (RES3) in phase and filter2 (RES2) + (filter4 (RES4) inverted. The result of these two outputs is a different frequency response with differently positioned notches for the BAND PASS and the NOTCH.
All parameters (Peak frequency, Bandwidth and Level) can be controlled manually (knobs) or by CV inputs, individually for all four resonators. Additionally, peak frequencies and levels, for all four resonators, can be controlled by linked CV inputs (MASTER CV FREQ and LEVEL)
The RES-4 has two switchable modes: bandpass and notch and it even has a bypass switch.

User manual MMF-6
The MMF-6 is a multi mode filter with six outputs, first three from the left; “clean” low pass, band pass and high pass. Low- band- and high pass to the right are processed by three separate (for every output) saturation circuits with two modes; soft and hard. Additionally, the filter core has so called “symmetry” control for the resonance and cutoff frequency. It is possible to control cutoff so positive and negative going signals has different cutoff frequencies, from a subtle “edge” to very dramatical character of the audio signal (including frequency division effect). All this by modulating symmetry by one of outputs (pre-patched to “clean” low pass output) or an external signal. Now it is possible to mix clean and saturated audio signals in any combination.
Inputs:
Audio: 2x In
CV inputs: 2x cutoff, 1x Q-peak, 1x symmetry
Outputs:
clean LPF, BPF and HPF
saturated LPF, BPF and HPF

The SPH-1 is a 14-stage stereo image phaser. It consist of two identical voltage controlled all-pass filters with seven notches stretched over the whole audio range which ensures constant phasing effect.
The all pass filters are combined with original audio signals resulting in an almost constant gain and phase shift of 2400 degrees across the entire audio range (see diagrams below).
Additionally, the phasing effect remain almost constant even in saturation mode.
Phasing (SPECTRUM) is controlled by modulating low frequency oscillator (MOD RATE, MOD LEVEL) and by external signals (SPECTRUM CV, and separate SPECTRUM LEFT, RIGHT).
The low frequency oscillator’s rate can be modulated by external signal (RATE CV, RATE CV INPUT).
The SPH-2 provides one audio input for both phasers labelled by SUM AUDIO.
The audio outputs are provided by output socket labelled AUDIO, LEFT, MIX (mixed left and right phaser) and RIGHT. Outputs are revealed by white surrounds.
The FEEDBACK knob controls the amount of multi resonance for both phasers up to self-oscillating.
The SPATIAL/ROTATING switch couples phaser between two different stereo images. The BYPASS/ L&R INPUT inserts both phasers in the audio chain in position L&R INPUT.
The main purpose with the frequency shifter is to make frequency shift up and down for processed audio signal. Two signal sources are needed; the carrier and the audio. Both carrier and audio signals are splitted in two chains and are pre-processed to accomplish 90 degrees phase shift between splitted signals.
The carrier generator has two frequency ranges; LF (low frequency) and AUDIO and it’s controlled by knobs
COARSE, FINE and external CV signals (CARRIER CV). The carrier generators outputs are pure sine waveforms with 90 degrees delay between them. Outputs are patched to both ring modulators inputs. Two ring modulators (dual balanced multipliers) receives 0 and 90 degrees shifted carrier and audio signals . The outputs from the multipliers are combined in two ways; the frequency shift UP and DOWN. The frequency shifted audio signal is a sum (UP) or difference (DOWN) of the carrier generators frequency (a pure sine waveform) and all audio signals frequencies (fundamentals and harmonics). The FSH-1 works in two modes; as frequency shifter and as dual ring modulator. A ring modulator is a classic audio effect device and due to the non-harmonic character of the output signal. It’s very useful to create metallic timbres such as bells, sweeping whistles and percussive sounds and tremolo effects. The obvious effect (particularly in LF mode) is a stereo panning effect of audio signal.
The BLD has all components and function necessary for generating bass lead and drum sounds with focus on bass drum sounds.
The BLD contain main sound generator (OSCILLATOR) and noise generator and modifiers such as low pass filter, amplifier and two transient (contour) generators.
Oscillator has two manual pitch controllers (FINE, COARSE) and two inputs for controlling the pitch by external signals (FM1, levelled, bipolar pre-patched to transient generator AR and FM2, calibrated to 1 Volt/octave).
Waveforms and mix between shapes is controlled manually from triangle, mix between triangle and pulse, pulse, mix between pulse and saw tooth and saw tooth).
Oscillator level is controlled manually from 0 thru nominal signal strength to saturated (curved, for more punch). Pulse width is controlled manually and by an external signa (PWM).
NOISE GENERATOR is connected to the low pass filter and to the amplifier (NOISE LEVEL). The noise generator can be routed in to the amplifier (PRE) or directly to the output AMP (POST).
The noise generators level is also controlled by pre-patched AR generator thru input NOISE LEVEL.
AR and AHR transient generators are activated manually by the push button
TRIG and/or by an external signal (input TRIG). Attack, Hold and Release are manually controlled and by an external signals connected to inputs A1, R1 (AR) and A1, HOLD and R2 (AHR).
AMPLIFIERs gain is controlled by mix of AR and AHR and by an external signaln connected to the input VELOCITY
