Braids user manual
Note: this user manual documents the version 1.5 of the firmware. If another version is
installed, please upgrade! You can find out which version is installed by clicking on the
encoder and scrolling to the end of the menu.
Overview
Mutable Instruments’ Braids is a voltage-controlled digital sound source. It features 33
waveform synthesis models, which cover techniques such as FM, wavetable synthesis,
waveguide synthesis or analog emulation. Most synthesis models are built with one or
several oscillators connected through crossfaders, modulators, filters, or delay lines. Each
synthesis model is controlled by 2 parameters, called Timbre and Color.
Installation
Mutable Instruments’ Braids is designed for Eurorack synthesizer systems and occupies 16
HP of space. It requires a -12V / +12V / +5V supply (2×8 connector), consuming 15mA from
the -12V / +12V rails and 85mA from the +5V rail. The red stripe of the ribbon cable must be
oriented on the same side as the “Red stripe” marking on the printed circuit board.
Controls
A: LED display and rotary encoder. When the module
starts, the LED display shows the name of the active
synthesis model, and the encoder can be used to select a
model. Click the encoder to display a list of additional
settings and options. Click the encoder to select an option
and modify its value. Once the value has been modified to
your liking, click the encoder to get back to the list of
options. Selecting the first option (“WAVE”), saves to
memory the current setup and brings you back in model
selection mode.
B, C: Fine and coarse frequency control.
D: Frequency modulation attenuverter. This knob controls
the amount and polarity of modulation applied to frequency,
from the FM CV input jack.
E: Timbre. This parameter controls the main evolution and
motion of the timbre – for example pulse width for a square
oscillator or modulation index for a FM model.
F: Modulation attenuverter. This knob controls the amount
and polarity of modulation applied to the TIMBRE
parameter, from the TIMBRE CV input jack.
G: Color. This knob controls a second dimension of sound, for example the symmetry of an
oscillator or the modulation frequency for a FM model.
