New Befaco A*B+C Eurorack Module

A*B+C Features Published on Mar 1, 2017 Befacosynth

"This video outlines the features of our A*B+C module. The A*B+C is a dual channel 4-quandrant multiplier with DC offset. It has many uses including VCA, 4-channel mixer and for creating true Ring Modulation.

0:29 - VCA
1:12 - 4 Channel Mixer
1:41 - Ring Modulation

The A*B+C is available as a kit, PCB & Panel set, or as an assembled module from our store www.befaco.com/en/tienda/"

"FEATURES

Each section can perform the analog multiplication of two signals (A and B) and add an offset (C). It can also act as a dual voltage controlled attenuverter, dual ring modulator, dual VCA or four channel mixer (see block diagram below).

The B inputs are routed to an attenuverter that multiplies the signal between -2 to 2, while the offset inputs (C) route through a unity gain attenuverter (multiplies the signal between -1 and 1).

B and C inputs are normalised to 5v and 10v respectively, so the A inputs can be processed using just the potentiometers.

The output of first block is normalized to the second one, so the second output can act as master to get (A1*B1+C1) + (A2*B2+C2)."

MS20 / JX3P / MFB522

"Some footy...

I saw Legowelt use his JX-3P (in an old clip on youtube) and it gave me the idea to use the MFB522 to trigger the built-in sequencer.

The PG200-like controller is actually a clone (prototype) made by a Dutch company called the DT200."

"Not the re-issue, but the real thing. Powers up, plays great, holds tuning as far as we can tell. Has been sitting unused in our studio and we are shutting down so our loss is your gain. One for the collectors."

"The RS-505 is a synthesizer which has 3 sections, bass, synth and strings. This piece of beauty has rich, analog sounds which are very warm.

The Synth section has 4 waveforms, which can be chosen by the white buttons located in the center section of the unit. The Synth section has its own filter cutoff, resonance, VCA, envelope and LFO.

The Bass section has three waveforms and this also comes with its own VCA attack and release sliders. The string has two presets and this part contains the features from the previous RS-202.

The sounds from the three sections can be blended to create interesting tones. This unit also comes with Chorus and Ensemble effects which can instantly warm and thicken the sounds up. The RS 505 is known to be Rolands one of the finest string synthesizer of its era, so a must have for your studio!!!"
