Befaco - Sampling Modulator
Sequencer Clocked Sample & Hold In this mode it acts like a regular Sample and Hold (S&H) but since it is “sequencer clocked”, it is capable of much more interesting patterns than the usual S&H melodies.
The CLOCK input can work in two ways: 1. As a typical clock 2. In “positive going hard sync” mode allowing you to create shuffling and polyrythmic effects.
The HOLD input can be used to keep certain notes playing.
Analog Down-Sampling Effect In this mode (with the clock running at audio rates) you can go from nasty and harsh sampling rate reduction to an almost clean signal. (The clock run up to 25Khz without external CV and up to 200Khz with CV on the input).
Sampling Modulator/Shaper Thanks to the V/Oct clock, by feeding a simple waveshape such as a sine wave to IN, and pitch CV to the VCO as well as to the Sampling Modulator CV input, their related frequencies and aliasing caused by the sampling rate reduction are capable of creating clangorous metallic sounds, 8 bit textures and much more.
The game becomes much more interesting when you try to destroy the wave by flipping on and off the switches of the sequencer (which at times can make it sound like three VCOs running in unison).
To understand how the Sampling Modulator works, keep in mind that we are working with a temperature compensated ramp core VCO with more than 4 octaves of tracking. This allows the timbre to stay the same while you move through the scale as the internal and external VCOs are synced in a fashion similar to “frequency related sampling rate modulation”
Unusual V/oct VCO You can use the trigger outputs as a pulse VCO. Flipping the switches on and off the switches can offer a lot of interesting timbral changes.

Befaco is an Eurorack manufacturer that also offers DIY kits, organizes workshops and releases their designs under Creative Commons license.
In February 2010 Befaco was created as an open hardware platform focusing on professional DIY musical hardware, materializing the previous electronic, musical and artistic research of its members.
Our main activity has been developing synthesizer modules in eurorack
format and making them available in workshops. All this research is
published under CC-NC-SA License, so people can download the schematics,
and technical assembly guides, to make their own variations of the
projects for personal and educative purposes. Also build all our designs
during our regular workshops in cities as Barcelona, Madrid, London or
Berlin.
During the past twelve years, apart of these regular four
cities, we have visited cities as Tokyo, Kyoto, Toronto, Montreal,
Chicago, Frankfurt, Helsinki, Lyon, Stuttgart and Amsterdam, amongst
many other European cities.
These workshops are a huge test playground where we can track each module being built by different worldwide users, get direct feedback and quickly improve them with, develop new ones, or adapt these instruments to users demands constantly.
Direct contact with DIY enthusiasts allows an implication of users in the structure, allowing them to design their own modules and develop them in a professional way. This has developed into an incubation environment for several new modular initiatives, allowing different makers to start their own similar projects.
Befaco initiative is possible thanks to the support of Hangar, an artistic production centre in Barcelona, Barcelona city hall and the titanic work by the whole Befaco team.
