"*2 analogue drum-sounds (Kick, Snare)
*dynamic trigger-inputs
*Kick with Attack and Decay controls
*Snare with Tune, Noise and Decay controls
*separate output for integrated digital Noise Generator
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)."
