"the drum-01 revives the kick- and snare sounds of the legendary seventies drum-machines mfb-301/302 as well as the model mfb-501. their unique sound is based on digital c-mos gates that produce less distortion than conventional opamp’s and therefore sound softer. bass- and snare can be triggered thru individual inputs. however, triggering does not need to take place with conventional analogue or digital signals only. you may as well use drum-pads or piezo- and dynamic microphones. separate sensitivity controls adjust the input gain. dynamic triggering will not only affect the volume but also attack and decay parameters.

drum-01 offers the following functions:
kick: attack produces a short impulse sound that is mixed with the kick drum signal to enhance its percussive character. decay defines the length of the kick – a parameter that was only adjustable inside the mfb-501.
snare: tune controls the tonal part of the snare sound while noise controls the atonal part. decay defines the length of the noise part after triggering.
noise out: this separate jack outputs the unfiltered signal of the digital noise generator. use it in combination with other modules to create hi-hats, claps or cymbals.

the module has a width of 40 mm (8 te).

delivering five different analogue generated percussion sounds, drum-02 is the best possible addition to mfb’s drum-01 bass- and snare-drum module. the sounds are tom, low bongo, hi bongo, low clave and hi clave. the sounds are vastly taken from the mfb-501 and offer individual decay controls.

accordingly to drum-01 module, drum-02 uses c-mos gates for a unique sound that is softer and less distorted than typical opamp’s circuit layouts. the c-mos gate are combined to work as a bandpass-filter with adjustable resonance. triggering of all five inputs can take place by digital and analogue signals. individual controls for input sensitivity also allow usage of drum-pads, piezo- and dynamic microphones. dynamic triggering will not only affect the volume but also its attack and decay level.

the matching step-sequencer for drum-01 and drum-02 will be forthcoming seq-1 module that will allow 12 trigger-tracks with individual outputs and accent function.

remark: the sounds h1 and h2 of mfb-501 have been renamed to low clave and hi clave in drum-02. tom and the two bongo instruments can also be used as three toms tuned differently. the module has a width of 60 mm (12 te).

the drum-03 module revives the cymbal, closed- and open hihat sounds that were originally found in mfb’s drum-machines mfb-301/302 and later on in model mfb-501. drum-03 complements drum-01 and drum-02 modules to a complete mfb old-school beatbox drum-set.

just like the other mfb drum modules, drum-03 has that specific mfb-sound that derives from analogue sounding digital c-mos gates. these units work with less distortion compared to typical op-amps and therefore sound softer. hihat and cymbal accept different trigger signals at their inputs. these don’t necessarily need to be analogue or digital trigger signals of a step-sequencer but can also derive from drum pads, piezo- or dynamic microphones. the two sens-controls will individually adjust the input sensitivity. dynamic triggering will not only affect the volume of the sound but slightly also attack and decay parameters.

drum-03 offers the following functions:
hihat: the sound source for the hihat is a digital noise generator that is sent into a bandpass filter. two parameters quality and filter offers different sound variations. decay controls the duration of the open hihat sound and also affects the closed hihat’s decay slightly. cymbal: the cymbal sound uses the same combination of digital noise generator and bandpass filer as the hihat section. here, only the bandpass frequency can be altered. decay sets the decay time of the cymbal with a range that is almost equal to the open hihat section. accordingly, the cymbal can also be used as a second hihat sound. with a shorter decay time it may complement the groove as a half open hihat.

the module has a width of 40 mm (8 te).
