Hardware stereo sound effect processor is designed to add depth and texture to electronic sounds 02/03/10
OTO Machines is a small French company, based in Paris who tell us they are dedicated to design new tools for music and sound creation.It has been created by two sound engineers & producer, sharing a same passion for
sound, music, and electronics.
OTO Machines' first product, BISCUIT is a stereo sound effect processor, designed, assembled and tested by them in their workshop. OTO Machines tell us that they use the best quality parts, choose not to outsource production and work with local companies. Here's what they have to say about Biscuit...
With its true 8-bit converters, digital processing and analog resonant filters, BISCUIT
opens up a wide range of sounds from harsh distortion, digital and aliasing artifacts to
warm and fat 8-bit sounds.
BISCUIT is very useful to add depth and texture to any kind of electronic sounds. It works
best with synthesizers (digital or analog), bassline, drum machines, loops, samplers or
computers, but you can use it with any other sources.
BISCUIT is basically an enhanced bit depth and sample-rate reducer, known as
"bitcrusher", followed by an analog filter. You can mix this 8-bit sound with the direct signal
via two separate knobs. It also offers other features like removing or inverting each of the 8
bits, changing the sample rate from 250Hz to 30kHz, or adding one of the four effects
(waveshaper, delay, pitch shifter and step filter).
Biscuit is MIDI compatible.
You can save the whole BISCUIT settings (pots and switches) in 16 presets.
A SysEx dump function let you save and recall as many presets you want on your
The main function of BISCUIT is to modify the 8 bits status thanks to the 8 rectangular
switches. Depending on the kind of modifications (bits inverted, muted; the bit number) the
conversion will reproduce a sound faithfull to the original or totally deconstructed.
Muting or inverting some of the bits can generate strong distortions, with an intense digital
You can add one of the following 8-bit effects to your bit modifications:
1/ Waveshaper: 8 types, including 3 oscillators.
2/ Delay: with controls for feedback and note value. It syncs to an external MIDI clock or
3/ Pitchshifter: from - 2 octaves to +1 octave in 8 steps.
4/ Step Filter: allows you to memorize and read up to 8 positions (steps) of the filter
Many settings of Play Mode, Speed and Number of steps are available.
It syncs to an external MIDI clock or TAP TEMPO.
All the BISCUIT functions (bit status, knobs positions, effects and filter settings) can be
saved in one of its 16 presets.
You can also save as many presets as you like on your computer using the Preset Dump
function (MIDI SysEx). MIDI:
Every pot, switch and effect setting can be sent or controlled by a continuous controller
message (known as CC).
BISCUIT can upgrade its firmware via a MIDI SysEx file.
