modular square Bell Modal Synthesis
Description
Bell is a melodic percussion generator based on modal synthesis. By synthesizing the vibrations of complex geometric shapes, Bell provides a simple interface for creating metallic sounds that can both emulate acoustic instruments, and defy physics. Its sonic palette includes numerous physical models that span the range of vibraphone, marimba, glockenspiel, and Tibetan bowls. In addition, damping allows for the articulation of all voices and enables drastically changing the tone of your patch with a single knob turn. It’s time to ring your Bell!
- Melodic percussion generator
- 6 Voice Polyphony
- Several physical models with the ability to mutate the physics of each one
- Damping control
Installation
To install, locate 2HP of space in your Eurorack case and confirm the positive 12 volts and negative 12 volts sides of the power distribution lines. Plug the connec-tor into the power distribution board of your case, keeping in mind that the red band corresponds to negative 12 volts. In most systems, the negative 12 volt sup-ply line is at the bottom. The power cable should be connected to the module with the red band facing the front of the module.
Specifications
- Size: 2HP

Functional Overview
Trig
Trigger input will cause a new note to be created with the current state of
the knobs and CVs. Six voices can be synthesized at once, and the oldest will
be replaced when a new trigger is detected.
Model
Selects from one of the eight following models of an exciter and resonator
made up of several modal filters.
- Pure Bell
- Pure Vibraphone
- Harmonic Vibraphone
- Hard Marimba
- Soft Marimba
- Tibetan Bowl
- Wine Glass
- Redwood Plate
Bipolar CV is added to the knob position.
- Input range: -5V to 5V
Damp
Changes the resonance of the excitor filters. This affects the overall decay
time of a given sound. A bipolar CV is added to the knob position.
- Input range: -5V to 5V
V/Oct
1V/Octave input was added to the pitch knob position.
- Input range: -1V to 6V
Pitch
Sets the fundamental frequency of the bell sound. The pitch control remains
active for the most recently generated note providing the opportunity for
vibrato, slew, and easier tuning while a note is ringing out.
Out
10Vpp audio output signal LED illumintates for 30ms when a new sound is
triggered.
