Products of MFB

MFB’s Loop ADSR is an exceptionally fast envelope with variable curve shapes. More precisely, you can crossfade between linear and logarithmic characteristic. Attack, decay and release phase can be edited manually plus there is a CV input per parameter. Thanks to a loop function, the module can be used as a LFO as well. The frequency goes up into the audible spectrum. In short: A great envelope for price savvy musicians!

The 24dB VCF SSI is an analog 4 pole low-pass circuit based on the SSI 2144. The chip is a redesign of the SSM2044, a legendary filter component to which lots of classic synthesizers owe their distinctive sound. In addition to a low-pass output with an edge steepness of -24 dB per octave, the module also emits low-pass or band-pass signals with a slope of -12 dB per octave. On the input side, there are two audio paths. One of them features an attenuator. Cutoff and resonance parameters are both voltage controllable.

MFB’s VCO/DCO is a hybrid oscillator. – It can be controlled via an analog or a digital control circuit. Thus, you have the choice between slightly drifting vintage flair and modern, very precise behavior. Apart from the FM input, all parameters are available in both modes of operation. The VCO/DCO generates saw, triangle, square and pulse waves. You can crossfade between said waves via a potentiometer.

The MFB VCLFO is a voltage controlled low frequency oscillator designed for modulation purposes. It offers five waveforms with wave shaping options, including a sawtooth / triangle / ramp combination and sample & hold with adjustable glide. The VCLFO’s frequency can be adjusted manually plus there is a CV input. Furthermore, a reset connector and a one-shot mode were implemented.

MFB’s Visual VCA is a voltage controlled amplifier module with built-in oscilloscope. The volume of the audio input can be adjusted. The oscilloscope is editable in its sampling frequency. Two CV inputs allow envelope control and amplitude modulation using, for instance, a LFO.

MFB’s Digital Delay is a creative effects processor for sound designers. The module comes equipped with an audio input plus level control, two timing and a feedback parameter as well as a mix section. The feedback path can be complemented by external modules. A CV input makes it possible to modulate the delay time. Via a button or a gate connector, a freeze function can be activated, which holds the current effect sound indefinitely.

The module CB/RS/MA-522 is composed of three drum voices, in detail a cowbell, a rimshot and maracas. The first two circuits are based on instruments included in the MFB-522, Tanzbär and Tanzbär Lite. For using them in a modular environment, some extras were implemented. The third voice was freshly developed for the CB/RS/MA-522. All drum types can be adjusted in their decay behavior. Additionally, cowbell and rimshot come with tune potentiometers. Trigger and CV inputs complete the circuit.
CB/RS/MA-522 responds dynamically to incoming trigger signals. Besides sequencers and MIDI/CV interfaces, the circuits can also be played using a drum pad, piezo element or dynamic microphone.
