User manual
OVERVIEW
Rings is a resonator, the essential ingredient at the core of several physical modelling techniques. It
transforms an external, unpitched excitation audio signal (such as a click, a burst of noise, or whatever is
captured by a contact microphone) into a full-bodied pitched sound. Rings is the bar, the tube or the bunch
of strings you cause to vibrate with an external signal.
INSTALLATION
Rings is designed for Eurorack synthesizer systems and occupies 14 HP of space. It requires a -12V /
+12V supply (2x5 pin connector), drawing 5mA from the -12V rail and 120mA from the +12V 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.
This device complies with part 15 of the FCC Rules. Operation is subject to the following
two conditions: (1) This device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesired
operation.
This device meets the requirements of the following standards: EN55032, EN55103-2,
EN61000-3-2, EN61000-3-3, EN62311.
RINGS’ BASICS
Polyphony and synthesis method
How the module operates is governed by two settings controlled by buttons at the top of the module. Once
these are set, no hidden mysteries! $
Polyphony selection
The first button selects the polyphony of the module: one, two, or four notes. Enabling four notes
polyphony doesn’t mean that four CV input jacks will magically appear on the module, but simply that four
notes played in sequence will nicely overlap without cutting each other’s tails. To play chords, you will
need to “strum” the module by playing a rapid sequence of notes - something you might have already
encountered with Braids’
PLUK
model. Note that the module might reduce the number of harmonics in the
generated signals to cope with the higher polyphony.
The second button selects the three available types of resonators. They are:
Modal resonator
Modal synthesis works by simulating the phenomena of resonance at play in vibrating structures, that is to
say the way a string or plate (for instance) will absorb certain frequencies while it will “ring” at some other
