#5 is a Cadence rate indicator LED.

Pitch: Set and control via knob, range button, and V/Oct CV for musical tracking.
Density: Morphs between classic subharmonic and noise textures by stretching/overlapping grains; main sound-shaping parameter.
Cadence (rate): Speed of the cyclic modulation of density (vibrato or audio-rate), CV controlled.
Torque (depth): Depth/amount of cyclic density modulation, CV controlled.
Shape: Smoothly crossfades through seven waveforms per grain, from soft to bright.
Coupling/Quantization toggles: Force tight/stepped relations between modulation rates and pitch for more musical/organ-like timbres.

Blend Square and Pulsar outputs for rich bass or hybrid tones.
Extreme Density: Far min and max produce noisy/rhythmic or digital textures.
Coupling/Quant ON: Maintains consistent pitch and creates stepped, "organ"-like transitions between timbres.
Standard VCO use: Use only Pitch, V/Oct, Linear FM, Sync, and Square Out.
Pulsar synthesis: Use Density, Cadence, Torque, and Shape controls—modulate them for evolving digital sounds.

Super PWM: Classic but richer pulse mod—from square and density mod.
Pocket Monsters: Wild digital screeches—modulate pitch/cadence.
Ghost Vibes: Fine/fleeting granular shimmer—fast, gentle density mod.
Spelunker: 8-bit, chirpy digital—low pitch + max density mod + saw/stepped shape.
Simple Sinc: Smooth, sine-like—low shape, varied density for gentle harmonics.
Captain Crunch: Bright, bell-like—pair audio-rate density mod with coupling.

Power: 10-pin ribbon (2x5), +12V: ~80mA; -12V: ~2mA
