Classic Split

Classic Split

Classic Split is a Generator Family derived from Classic Waveforms. It opens a zero-valued flat region through the centre of the cycle while the active lobes compress outward toward the edges. Choose Classic Split under Core Generator → Generator Family in Playground or either Morph endpoint.

Keep Topology and Symmetry / Width where you want them, set Split to 0, then raise Split while listening to tap A. Once the basic motion is clear, try Crunchy and the other taps.

Split geometry

🔧 Technical: Split maps the full 0…4095 control range onto every legal integer central-flat geometry in the 512-internal-cycle-sample table.

  • Split 0: exact neutral Classic (Character = 2048).
  • The flat region can grow from 0 through 506 internal cycle samples.
  • Each successive geometry adds one flat sample. Left and right boundaries alternate, so two increments expand the flatline symmetrically as a pair.
  • pot3=2048: exactly 256 flat internal cycle samples, leaving 128 active samples on each side.
  • pot3=4095: exactly 506 flat internal cycle samples, leaving three active samples on each side.
  • There is no early top-end clamp plateau.

Once a flat section exists, the left compressed half owns phases below 180° and the right compressed half owns phases above 180°. Neither lobe interpolates through the original Classic half-cycle discontinuity.

Smooth and Crunchy

🎹 Smooth keeps the Split geometry clean. Crunchy adds resonance around the two boundaries of the inserted flatline. Tap A is the stronger/longer resonator; tap B adds restrained harmonic grit; C and D keep their established edge-focused character.

🔧 Technical: Crunchy's base excitation follows the signed source value immediately beside each boundary, so hard level steps retain strong polarity-continuous resonance. Taps A/B also receive a signed slope-to-flat excitation term, allowing curved, triangular, and intermediate edges to ring even when the waveform meets the flat region near zero amplitude. That slope supplement is strongest through lower/middle Topology/Symmetry values and contributes less as the boundary approaches an already-strong vertical edge.

There is no whole-lobe polarity vote, exact-tie rule, or arbitrary minimum resonance floor. Treatment vanishes at Split 0.

Scanning wrappers

Wrapper Pot recipe
Scanning – Classic Split Sine [0, 2048, scan]
Scanning – Classic Split Triangle [2048, 2048, scan]
Scanning – Classic Split Square [4095, 2048, scan]
Scanning – Classic Split Saw ↑ [2048, 4095, scan]
Scanning – Classic Split Saw ↓ [2048, 0, scan]
Scanning – Classic Split Pulse [4095, 512, scan]

These are ordinary Scanning wrappers over Classic Split. Both variants and all A–D taps remain available. Classic Split and all six wrappers can enter broad Unrestricted and Absurd random generation.

🔧 The broad Generator lottery chooses ordinary/base versus Scanning first, so adding Scanning wrappers does not crowd ordinary Generator Families out of the broad pools.
