Alternate/DIY panel for Elements
Alternate/DIY panel for Elements, designed by Grayscale:
Elements is a full-blown synthesis voice based on modal synthesis - an under-appreciated flavour of physical modelling synthesis with a strange and abstract feel.
Elements combines an exciter synthesis section, generating raw, noisy sounds characteristic of bowing (filtered friction noise), blowing (pitch-controlled granular noise), or striking (stick, mallet, hammer or brush sample playback... or bursts of synthetic impulsions). These sources, or external audio signals, are processed by a modal filter bank - an ensemble of 64 tuned band-pass filters simulating the response of various resonant structures (plates, strings, tubes...) with adjustable brightness and dampening. A stereo ambiance reverberator adds depth and presence to the sound.
All parameters have a very meaningful and well-delimited impact on the sound. When designing Elements, a great care has been taken in selecting parameter ranges and control curves producing a large palette of sounds - often beyond physical realism - but always well controlled and stable. The "dark spots" of noise and feedback are reached gradually, and they do still react to controls. The module is deliberately menu- and switch-free - what you dial/patch is what you hear!
Excitation signal generator
- Three generators with mixer: bowing noise, blowing noise, percussive impulses.
- Envelope contour for bowing and blowing.
- Bowing noise generator: particle-like scratching noise with 2-pole low-pass filter.
- Blowing noise generator: granular pitched noise with wavetable-like scanning between various tone colors.
- Percussive impulse generator: interpolates through a collection of impulsive excitations – including sampled sticks, brushes and hammers, and models of damped mallets, plectrums, or bouncy particles. 2-pole low-pass filter and pitch control.
- Internally uses 64 zero-delay state variable filters.
- Coarse, fine and FM frequency controls.
- Geometry: Interpolates through a collection of structures, including plates, strings, tubes, bowls.
- Brightness. Specifies the character of the material the resonating structure is made of – from wood to glass, from nylon to steel.
- Damping. Adds damping to the sound – simulates a “wet” material or the muting of the vibrations.
- Position. Specifies at which point the structure is excited.
- Space. Creates an increasingly rich stereo output by capturing the sound at two different points of the structure, and then adds more space through algorithmic reverberation.
Inputs & Outputs
- All exciter and resonator parameters have a dedicated CV input with attenuverter.
- 1V/Oct input for controlling main resonator frequency.
- FM input.
- Gate input.
- Strength input, for amplitude control of the exciter section.
- Pre- and post- exciter envelope external audio inputs.
- Stereo audio output, with adjustable width/reverberation. It is also possible to output the raw exciter signal on one channel, and the raw resonator signal on the other.
- Input impedances: 100k.
- CV range: +/- 8V. CVs outside of this range are simply clipped.
- Audio acquisition and restitution: 16-bit, 32kHz.
- Internal computations on 32-bit floating point numbers.
- Open-source hardware and firmware.
- Easy firmware updates through an audio interface.
- Cortex-M4 ARM processor.
- Current consumption: +12V: 130mA ; -12V: 10mA.
Available as an assembled Module and as a DIY project.
