Although MEGAZWERG and its many useful functions are meant to serve as an expansion to MFB’s KRAFTZWERG or any analogue modular-system, MEGAZWERG also serves as an independent full-featured synthesizer. Its ten sections can be used individually or combined.

A brief overview to the sections of MEGAZWERG:

The oscillator offers triangle, saw tooth and rectangle waveform shapes. Its pitch can be set over an octave range using a trim-pot. Pitch is controlled by its CV-input using sequencers or keyboards. The output is prewired to the Y-input of the ring modulator, which is built analogue unlike the unit found in KRAFTZWERG. The ring modulator may also be used with two external signals.

The state-variable multimode-filter runs with 12dB slope per octave and offers Lo-, Hi- and Bandpass-modes as well as notch-filtering and resonance up to self-oscillation. Both, cutoff and resonance can be modulated using dedicated CV-inputs. In addition, a pitch-dependent cutoff-frequency control can be achieved using the key follow function. Key follow is prewired to key-CV respectively MIDI-pitch.

The envelope generator offers Attack, Hold, Decay, Sustain and Release stages. Besides its normal mode, the first three stages can also be looped with an active gate-signal, and then followed by the release stage. This section also contains a VCA that serves as CV-controllable audio-output for MEGAZWERG. The envelope is prewired to the CV-input of the VCA.

The onboard 12-bit-Digital-Delay does not only create echo-effects. Its read-out-speed can be varied over a two-octave-range manually or by CV. In addition, there is a freeze function that sets the effect signal to last endlessly. Send and return jacks are provided to insert any module into the delay’s feedback-path, just like a filter or a ring modulator.

The modulation-sequencer serves to create simple, adjustable rhythmic modulations of two, three or four steps in length. Each step has a dedicated control to set the according control voltage. The sequence tempo can be adjusted with the sequence or follow the clock-input.

The dual Glide section offers two independent delay/lag units with different characteristics. You may use these to smooth the steps of the modulation-sequence or create portamento glides.

Two attenuators are available in the Dual-Attenuator-Section. In excess of limiting audio- and control-signals, these units can also serve as CV-sources. With the input not being patched, the output sends a fixed control voltage of up to 8V. This can be used to increase the maximum speed of KRAFTZWERG’s LFO or set the VCO-pulse width to a constant value.

The mixer section offers three inputs, where only inputs 1 and 2 are variable in gain.

Two multiples allow doubling or tripling CV- or audio-signals. Essential, where one LFO needs to modular two or three targets.

The signal-path VCO-VCF-VCA as well as envelope control over the VCA is internally prewired, so that MEGAZWERG can be played immediately. All further routings are created using the patch jacks. These can be used or controlled by MEGAZWERG itself or any compatible external device.

MFB’s MEGAZWERG has the following dimensions: 310 x 165 x 38/72 mm.

External power supply included."

MICROZWERG not only bridges the gap between NANOZWERG and KRAFTZWERG. Due to its dual multimode-filter, it also offers an individual signal-path with specific sound potential. MICROZWERG’s numerous patch connections are simply inviting to be modulated by our flexible step-sequencer URZWERG or to interact with the multifunctional MEGAZWERG.

Individually operated and due to its dual oscillators and dual multimode-filter, MICROZWERG offers a lot more than typical analogue basses and lead sounds. Prepare yourself for some special timbres. The signal path and modulations are quickly reconfigured using a few patch chords with the result of an enormous boost in sonic variety. Combined with other members of MFB’s ZWERG synthesizer family or even a modular system, MICROZWERG’s possibilities grow further.

A brief overview to the sections of MICROZWERG:

Both oscillators offer triangle, saw tooth and rectangle waveform shapes. Where oscillator 1 also offers a needle impulse, VCO 2 has a built-in noise generator. VCO 2 can be detuned by plus minus one octave in reference to VCO 1. Both oscillators can also be synced, using a patch connection. In addition, the separate output of VCO 2 can be used to modulate the filter. Finally, ring modulation is possible in combination with MEGAZWERG, where the ring modulated output can be fed back into MICROZWERG.

The two state-variable multimode-filters run with 12dB slope per octave and offer lo-, hi- and bandpass-modes as well as notch-filtering. The filters are prewired in series to increase the slope when used in same operation mode. Here, the slope is variable because both cutoff-controls can be shifted against each other using the slope control. Combining a lo- and hipass-filter result in a variable band pass with adjustable bandwidth and individually controllable resonances. When preferred, a parallel routing is possible using a patch connection, too. In this case, MICROZWERG allows two separate shifted bandpass-filters, notch-filtering with variable bandwidth or a combination of bandpass-filter with followed lo- or hipass-filter. Resonance can reach up to self-oscillation for both filters. The cutoff-frequencies are manually controlled simultaneously or by envelopes. They can be shifted against each other using the space-control. Modulations by LFO or CV can address either filter 1 or both filters.

A simple patch from Key CV to the contour- or mod-input can achieve pitch-dependent cutoff-frequency control. Because both filters offer independent in- and outputs, MICROZWERG is also destined to be used as an effective dual-filter for external sound sources.

The ADSR envelope is internally prewired to control the filters’ cutoff-frequency. MEGAZWERG or any modular system can jump in via patch chords whenever a second envelope is needed.

The two LFO offers four waveform shapes each and a one-shot-function, where the selected waveform is played only once after a gate-trigger, thus imitating a simple envelope that might be used for pitch or VCA control. LFO 2 includes a sample & hold.

Internal modulation wirings offer LFO control over the filters’ cutoff as well as the oscillators’ pitch or VCO 2’s pulse width. LFO 2’s speed can be modulated by an external control voltage, allowing increasing or decreasing the speed by a factor of 30. Using this feature, MICROZWERG is capable of extreme slow and fast modulations.

The control signals of the envelope and both LFOs are available as CV-outputs and can therefore be used to control other functions of MICROZWERG as well as in other analogue synthesizers and modular systems.

The signal-path VCO 1/2-VCF 1/2-VCA as well as the common main modulations is internally prewired, so that MICROZWERG can be played immediately. All further routings are created using the patch jacks. These can be used or controlled by MICROZWERG itself or any compatible external device.

MICROZWERG can be controlled by MIDI from any compatible keyboard or DAW. Note commands are received as well as pitch-wheel (+/- 2 semitones) and modulation-wheel data, the latter controlling the filter’s cutoff frequency.

MFB’s MICROZWERG has the following dimensions: 175 x 125 x 38/72 mm.

External power supply included."
