🎛️ Output Controls

Pan Jitter (0-1)

Random stereo positioning per grain

Grain Gain (0-1)

Dry/Wet Balance

Original Source Granulated

Pool Size (20-200)

Node pool size – higher = more concurrent grains possible

🎲 Randomness & Variation

Grain Size Jitter (0-1)

Random variation in grain duration

Playback Rate Jitter (0-1)

Random pitch variation per grain

Timing Jitter (0-1)

Random variation in grain start timing

Envelope Jitter (0-1)

Random variation in ADSR envelope values

⚡ Cache Performance

Jitter Cache Update (ms)

How often jitter values refresh (lower = more variation, higher = better performance)

Grains Per Jitter (1-20)

How many grains use same jitter value (lower = more random, higher = better performance)

Loop Cache Update (ms)

How often loop positions refresh (lower = more variation, higher = better performance)

Loop Cache Size (5-30)

Number of pre-computed loop positions (higher = more variety before repetition)
