So, what exactly is this granular effect and why is it a magical experience when combined with delay? Granular is a digital processing technique of micro-sampling, wherein short samples called grains are read from a delay buffer. In the Fable, players can adjust these grains by manipulating their sampling length, position, and buffer size from which they’re read. They can be played at double or half speed for pitch shift and time stretching effects, play them in reverse, read from multiple positions, and more, in order to achieve different effects.

• Program 1 runs a reverse delay into a reverse granular algorithm, in which sampled grains are played backwards. Reversal and re-reversal build up in the feedback paths, creating a complex and organically shifting soundscape.
• Program 2 runs a forward delay into an octave-up granular program, in which sampled grains are played at double speed. Swarms of double-speed grains build up in the feedback path for bright and airy cascades of sound.
• Program 3 runs a warm, dark analog-style delay into an octave-down granular program, in which sampled grains are played back at half speed. Slowed down repeats combine with analog-style processing to create deep, thunderous footfalls and thick, murky ambience.
• Program 4 runs two multi-tap granular algorithms in series, in which multiple samples are played back from each granular buffer simultaneously. Multiple points of sampled sound build upon each other in the feedback paths to create glitchy clouds and unique organic reverberance.
• Program 4 runs a forward delay into a randomized pitch granular program, in which each grain is played back at a randomly selected speed and direction, varying between pitched up double speed, pitched down half speed, normal speed, plus forward and reversed playback from grain to grain.
