schlagzwerg combines the power of analogue drum and percussion sounds with modular versatility in a convenient and compact desktop unit. schlagzwerg fusions cv-controllable percussion modules and a six-track cv/gate-sequencer into a unique drum-machine for live and studio applications.

thanks to its semi-modular concept, schlagzwerg is ready to go without any need for patch-connections. its internal pre-wiring comprises trigger-assignments for the gate-tracks of five (of six) drum-sounds as well as hihat decay-control. the additional cv-tracks can freely be patched to any of the modules’ functions. naturally, the available cv-inputs can also be addressed by external control sources like lfos, envelope generators or a theremin-controller.

an additional cv/gate-track-pair can be used to either control a variable function of a drum-module or an analogue synthesizer like mfb’s kraftzwerg. the cv-track output is quantized in pitch for perfect tuning.

the internal sequencer can store sixteen patterns, each holding a- and b-parts. patterns can be advanced using gate-signals as well as thru start/stop and reset remote inputs. the sequencer can be externally synchronized. start/stop and clock-sync can also be remote controlled from the units midi-input without any further patch connections.

schlagzwerg will double as a sixfold midi-cv/gate-converter. two modes cover drum-sound control and a basic cv/gate-output of the sequences. two additional modes allow conversion of incoming midi-data into cv/gate with the internal sequencer being inactive. here, every drum sound is controlled by an individual midi-channel with a pitch range of two octaves. a separate channel with five-octave-range is used for synthesizer control.

the individual drum-sounds derive from our mfb’s drum-sound-modules. trigger inputs are level-sensitive and allow dynamic performance thru drum-pads, piezo-pickups or microphones. all drums offer cv-inputs for different parameters. in difference to our modules, the different drum-sounds do not need attenuators because the sequencer allows for scalable cv-output.

the bass-drum offers the powerful sound mfb’s mfb-503 drum-machine respectively our drum-04 module. it offers a wide variety of possible kick-sounds due to its parameter-set with attack, tune, decay, pitch and drive.

the snare-drum is also based upon the mfb-503, respectively our drum-05 module. snap, decay, tune and pitch parameters allow for broad sound-variations.

the tom-sound derives from the mfb-503 respectively our drum-06 module. here, pitch and panorama-position can be coupled to achieve the classic pan-spread sound of hi-, mid- and lo-toms.

hihat and cymbal derive from our mfb-522 drum-machine, respectively drum-07 module. the sounds are based upon a six-oscillator-mix. cymbal, open and closed hihat can be triggered separately. in addition, the decay of the cymbal- and open-hihat-sounds is under cv-control.

all drum-sounds are routed into the internal mixer with adjustable panning and stereo outputs. alternatively, the sound modules also offer individual outputs.
