    • Pulse train with limited bandwidth with wavefolder
    • Double square or sawtooth wave with hard sync
    • Triple sawtooth, square, triangular or sine wave
    • Series of three ring modulated sine waves
    • Seven sawtooth wave swarm
    • Sawtooth wave with comb filter

    • Noise processed by a tuned multimode filter - Noise processed by a dual band-pass filter - Clocked digital noise
    • Cloud of sinusoidal grains
    • Particle synthesis

  • 8 x ADSR for each track

  • 8 x Moog Ladder filter for each track

  • 8 x multi-waves LFO for each track

  • 8 x Euclidean sequencers with microtonal scale calculation

  • 10 x different sends to FX for each synth:

    • Hall reverb (Reverb of the Rings module by Mutable Instruments)
    • Plate reverb (ELSE)

    • rendering mode (lines, plane and points)
    • line width, transposition on the X axis
    • transposition on the Y axis
    • transposition on the Z axis
    • repetition
    • rotation on the X axis
    • rotation on the Y axis
    • rotation on the Z axis
    • RGB values of the first form
    • RGB values of the last form
    • choice of shape
    • radius of the sphere
    • sides of the polygon of the sphere
    • radius of the circle
    • rim geometries
    • XYZ values for all vertices of the triangle
    • width and height of the top
    • number of rows and columns of the plan.

  • Global transport logic with BPM control

  • Interactive GUI with buttons, sliders and knobs

Hardware needs
