delay
How the two rivers of echoes behave.Delay sync locks the echoes to the tempo. Delay beats goes up to 4 bars.Time sets the longest echo. Stretch scales the gaps between buoys.Feedback sets how many echoes come round again.Cross shares returning echoes with the other lane. Zigzag has every other buoy listen to the other lane.Mix balances source and echoes.Spread pans A left and B right. Swirl turns echoes around the stereo field.Weather follows the dirt, or stays calm or stormy.

Effects sit in three places along the water.Before changes sound entering a lane. Feedback changes every echo as it comes round. After changes only what you hear.Tap an empty socket to add an effect. Drop one on the × to remove it.Speaker clips like a small speaker. Grit roughens and filters.Tremolo pulses the level. Phase sweeps.Stutter repeats a slice. Reverb adds a short tail.Tape adds a worn, wobbly warmth. Ensemble is a slow chorus.Formant filters towards the vowel you set.Settings here apply to both lanes.
rhythm
Patterns for each lane. Tap A or B in the valley to jump here.Steps let new sound in. Echoes keep going through closed steps.Length sets 4–16 steps per lane. Lanes of different lengths drift apart.Pattern fills the steps. Add tap puts another buoy in the lane.Tempo sets the speed of the steps and of synced times.Link lanes makes lane B follow lane A.Each buoy's chance is in its card.
Lanes as a list
This browser can’t draw the valley, so each lane is shown here instead. Drag taps to set when each echo sounds.
