Ableton/Live/UG/29 Audio Effect Reference/22 Grain Delay
- Grain Delay chops the input into tiny grains and delays each one, optionally at a different pitch. Randomizing pitch and timing creates textures that may barely resemble the source.
- Any parameter can be put on the X-Y controller: pick the X parameter from the row below it and the Y parameter from the row at its left. Delay time can go on X and dry/wet on Y.
- Sync on — delay in sixteenths from numbered buttons (4 is one beat); the Delay Time percentage nudges it for swing. Sync off — delay in ms.
- Spray — random delay-time changes; low values smear and add noise, high values break the source into rhythmic chaos
- Frequency — sets grain size and length, and so shapes how Pitch and Spray sound
- Pitch — transposes the grains, like a rough pitch shifter
- Random Pitch — random pitch per grain; low values give a warped chorus, high values make the original pitch unrecognizable
- Feedback — output fed back into the delay; very high values can run away into loud oscillation
- Dry/Wet — balance of processed and dry signal
