Struct Granular 

pub struct Granular { /* private fields */ }

Granular synthesis/processing engine

Records input audio into a circular buffer and plays back overlapping grains with individual pitch shifting and envelope shaping.

Ports

• Input 0: Audio input
• Input 1: Playback position (0-1 maps to buffer position)
• Input 2: Grain size (0-1 maps to 10ms-500ms)
• Input 3: Density (0-1 maps to 1-20 grains per second)
• Input 4: Pitch shift (bipolar CV ±5V maps to ±24 semitones, i.e. playback speed 0.25×–4×). Grain size is bounded so a grain’s read span can never exceed the buffer length at the chosen speed.
• Input 5: Spray (position randomization, 0-1)
• Input 6: Freeze (gate > 2.5V stops recording)
• Output 10: Processed output
