Free State FX FSFX107: Supra Resonator
NoiseBug Price : $430
This module is Two (2) MU Wide and is less than 2" deep behind the front panel (Box-11 Friendly).
The Free State FX Supra Resonator module (aka Rings) enables
physical modeling techniques never previously available in MU/5U. It can
be thought of as a group of strings that can vibrated using a variety
of input signals.
Polyphony: One, Two, or Four notes
Resonator Types: Modal, Sympathetic Strings, Modulated/Inharmonic strings
Latest Mutable Instruments firmware installed
Operates on +/-15V
Synthesizers.Com power header
C&K Pushbutton Switches
1/4" Switchcraft Jacks
Rings brings physical modelling synthesis to your open-architecture synthesizer, from a
more modular angle than Braids’ models or Elements. Instead of trying
to be a complete instrument, Rings focuses on the key ingredient, the
resonator, ready to be excited by envelope clicks, trigger pulses,
granular noise or any other audio source produced by the rest of your
Three families of vibrating structures are simulated by the module, with CV control over their parameters:
Strings, membranes and tubes as modelled by Elements’ resonator section (modal synthesis).
Strings coupled together and vibrating in sympathy, with controllable intervals between them.
Strings with a variable amount of inharmonicity.
Rings can be configured so that each new note is played on its own
virtual string, while the previously played note(s) still decay(s).
unique take on polyphony allows the module to play strummed chords.
Modal filter bank and comb-filtered based resonator, for physical modelling synthesis.
Three resonator models: modal resonator (as used in Elements),
sympathetic strings (stack of comb filters), string with
non-linearity/dispersion (comb filter with multimode filter and
non-linearities in the loop).
Pseudo-polyphony of up to 4 notes. Each new note is played on its
own virtual string, while the previously played note(s) still decay.
Number of strings/structures (1, 2 or 4).
Synthesis model (modal, sympathetic strings, string).
Main frequency (quantized in semitones).
Structure. With the modal and waveguide models, controls the
inharmonicity of the spectrum (which directly impacts the perceived
“material”). With the sympathetic strings model, controls the intervals
Brightness. Specifies the brightness and richness of the spectrum.
Damping. Controls the damping rate of the sound, from 100ms to 10s.
Position. Specifies at which point the structure is excited.
Inputs and outputs
Frequency, structure, brightness, damping and position modulation CV inputs with attenuverter (-8V to +8V).
“Strum” trigger input to indicate when a new polyphony voice needs
to be allocated. Normalized to an edge detector detecting changes on the
main V/Oct input, or sharp transients on the audio input. Detection
threshold at 0.6V.
1 V/Oct frequency input (-1V to +5V).
Resonator audio input, normalized to a filtered pulse/noise burst
triggered by the “Strum” input. Modular level, up to 16Vpp.
Two audio outputs, splitting the signal into even/odd partials in
monophonic operation, or even/odd notes in polyphonic operation.
Input impedances: 100k.
AD/DA: 16-bit, 48kHz.
Internal processing: 32-bit floating point.
Open-source hardware and firmware.
Easy firmware updates through an audio interface.
Cortex-M4 ARM processor.
