MFB Urzwerg MK1 Sequencer
Please check back for more stock at a later date!
This used Urzwerg is fully functional and in excellent condition. Includes its PSU.
Urzwerg offers 32 steps that can either be used in two sequences with 16 steps each or as four sequences with 8 steps each. Accordingly, up to four synthesizers or cv-parameters of a modular system can be addressed simultaneously. when in 4 x 8 mode, Urzwerg could control four Nanozwerg units polyphonically. Another example would be independent control over pitch, pulse width, filter-cutoff and lfo-speed on a single Kraftzwerg. In combination with a modular system, possibilities are finally vast. Urzwerg’s gate- and cv-inputs are compatible to all common modules for the eurorack-system.
Urzwerg was designed for intuitive operation. All functions have designated controls that can be edited while the sequencer is running. Steps can be set and edited live, as well as the sequence direction and the sequence length for each individual row.
Urzwerg allows setting of independent gate-lengths, ranges and glides for rows 1/2 and 3/4. range defines the cv-range for the step-knobs between 1-10v. For pitch control, the range can be quantized to 5v. All four rows feature skip-buttons per step to activate/deactivate gate-triggers for these positions. Alternatively, the skip-buttons can also deactivate the cv-step-control. To add more liveliness, urzwerg also offers two optimized shuffle-modes.
Urzwerg provides four gate- and cv-outputs to control compatible analogue synthesizers and modular systems. Start-i/o and clock-i/o allow urzwerg to be synchronized to and sync other analogue sequencers. The additional cv-clock-input allows for dynamic tempo-control, e.g. using an external lfo or a cv-controller.
To be synchronized to midi-sequencers, Urzwerg can send and receive midi-start/stop commands as well as midi-clock. Furthermore, Urzwerg’s sequences can be transposed, advanced stepwise as well as its steps being directly addressed using a midi-keyboard or DAW.
