E.
TIME controls if the grain replays the most recent (fully
CCW) or oldest (fully CW) audio material from the recording
buffer – shifting the replay heads further apart from the
record head.
Beads does not make use of any time-travel
technology: if you request a grain to be played at double
speed, one second away from the start of the buffer, the
grain will fade out and stop after 0.5s of playback, once
the replay head bumps into the record head. (Suggested
reading: "Light cones in tape recorder cosmology").
F.
PITCH controls the transposition, from -24 to +24 semi-
tones, with virtual notches at selected intervals.
G.
SIZE controls the duration and playback direction of the
grain. At the 11 o'clock position, a very short (30ms) grain
is played. Turn CW to increase grain duration up to 4s. Turn
CCW to play a reversed grain, lasting up to 4s.
Turning SIZE fully clockwise (∞) generates never-ending
grains acting as delay taps. Please refer to the "Beads as a
delay" section.
H.
SHAPE adjusts the amplitude envelope of the grain.
Fully CCW creates clicky, rectangular envelopes, while fully
CW provides envelopes with slow attacks reminiscent of
reversed grains (Please note, however, that the envelope
shape is independent of the playback direction).
I.
Attenurandomizers for the TIME, SIZE, SHAPE and PITCH
parameters. They control the amount of external CV modu-
lation on the corresponding parameters, or repurpose the
CV input
(6)
as a randomization or "spread" control.
