mfb drum-07 price : $175.00

the drum-07 module is based upon the cymbal- and hihat-sound-circuit of our mfb-522 drum-computer, slightly modified and expanded. in comparison to the drum-03 module that also generates cymbal and hihat sounds, drum-07 does not use white noise as sound source but a metallic oscillator mixture.

drum-07 was developed as a modular component. therefore, the parameters decay for cymbal and open-hihat and tone can also be controlled by cv-sources like envelopes, lfos, step-sequencers. manual adjustment is available for the parameter tune that affects both cymbal and hihat as well as for the closed-hihat’s decay.

triggering open-hihat, closed-hihat and cymbal of the module is possible through various signal types. besides sequencer generated analogue and digital trigger-signals, drum-pads, piezo- and dynamic microphones may also be used. here, the sens-controls allow individual adjustment of the input sensitivity. dynamic triggering will not only affect the sound’s volume but also attack and sound length slightly.the functions in detail:

hihat:
the hihat sound is created by several square-oscillators that are fed into a band-pass-filter. two decay controls allow individual sound-length-adjustments for closed- and open-hihat. in addition, the decay parameter for the open-hihat can be controlled by cv-voltage. tune sets the frequency for all square-oscillators simultaneously. because the cymbal sound accesses the same oscillators, tune also affects this sound.

cymbal:
the cymbal sound is based upon the same sound source as the hihat, only that it uses two band-pass-filters that individually shape the attack- and decay-phase. however, the decay parameter controls the length of both attack and sound length. this parameter can also be controlled by an external cv-source. tone sets the balance between the differently filtered signals paths. this parameter is also under cv-control but does not offer an internal attenuator. a specialty of the cymbal sound is its tone-input. here, you can connect an external sound source that replaces the drum-07’s internal square-oscillators for the decay phase. the internal oscillators are still in use for the sound’s attack-phase.

the module has a width of 60 mm (12 te). it is equipped with a connector cable compatible to doepfer’s system-bus.
