MFB DRUM-03 HH/CY501

via this auction

"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)."
