granular synthesis with rhythmic stutter and scatter

seph is a granular synthesis effect built around rhythmic stutter and scatter trails. grains fire from a rolling 4-second buffer at a rate and position you control. scatter loosens the timing from a locked clock into a randomized cloud. freeze holds the buffer so the cloud sustains and slowly evolves.

controls

size

grain duration in seconds

dens

grain trigger rate (grains per second)

wet

dry/wet blend

rcyl

fresh input vs recycled output

wher

how far back in the buffer grains read from

scatter

timing jitter (0 is locked rhythm, 1 is full cloud)

toggle a

[on-on] grain window: hann (smooth trails) / rect (choppy stutter)

toggle b

[on-off-on] grain overlap: sparse (2) / mid (4) / dense (8)

toggle c

[on-on] wher range: short (~1s) / long (~4s)
