Architecture
arc*C is a 4 voice polytonal instrument in which each voice can continuously arc between two independent synthesis engines. Spectral / phase distortion. Core system attributes include a 32 complex envelope matrix, X4 complex 3-d lattice sequencers, x4 DSP algorithms, a partnered drawing app to paint sound with Google Gemini API integration, 3.2’’ AMOLED display, CNC-machined aluminium case.
> 500 harmonics
for FFT stretching, warping, combing and morphing.
2 large experimental LUTs each with scanning and 4-quad multiplication
phase warping
Envelope matrix, 3-D Lattice Sequencers, DSP, Google Gemini API & arc*C app.
This core is built around 32 complex envelopes and an envelope matrix for all points of control and modulation within the system. These envelopes can have up to 80 break points and the ability to control segment count, segment looping, rate, amplitude, rate modulation and cycle source, and can be individually randomised or randomise the entire envelope matrix.
3-D lattice ×4:
arc*C also has ×4 X-Y-Z lattice Cartesian-like sequencers, represented by four mathematical shapes. Each one steers an invisible point through an 8 × 8 × 8 grid and is constrained by division, jitter, swing, stochastic ratchet/repeat subdivision, axis modulation, snake and orbit shape control, 16-scale index, and per-cell parameters (rest/ratchet %, gate %, probability). These can be the basis of chordal polymetric movements, complex spectral drum rhythms and more.
arc*C has ×4 unique DSP algorithms:
Gorbachev gas 2: 16-pole phaser with through-zero, per-stage coefficient offsets and feedback/resonance.
pnp=f: through-zero flanger.
loraxong space 2: Hadamard-matrix reverb / FDN structure.
time cube: experimental 6-min regen delay.
