DELAY
A-Filter’s analog filter is an insanely squelchy dual filter with 8 varied filter types. By “dual filter”
we mean, of course, that certain filter types in fact combine two filters in series or parallel and
allow their respective frequencies to be offset, creating a vast range of possible tones. With
each control being assignable to the envelope follower, A-Filter is the tool par excellence for
adding instant analog charm to any sound.
Time L — Sets the delay time of the Left channel. This time can either be synced or free,
depending on the setting of Sync. Synced times range from 1/64 to 1 bar, while free delay
times range from 10ms to 1000ms. Note: if the Stereo button is active, Time L controls both
the left and right delay times in tandem.
Time R — Sets the delay time of the Right channel. This time can either be synced or free,
depending on the setting of Sync. Synced times range from 1/64 to 1 bar, while free delay
times range from 10ms to 1000ms. Note: if the Mono button is active, Time R ceases to have
any effect as the right delay time becomes linked to the left.
Feed — Controls the feedback level of the delay. Feedback can either be positive or
negative, depending in which direction this bipolar knob is turned.
Freq — Controls the grain delay engine’s grain frequency (ie. the number of grains produced
in a single second). Values range between 1 and 150 Hz.
Pitch — Controls the pitch of each individual grain, allowing for delays whose pitch cascades
upwards or downwards (depending on the value of this parameter and on the feedback
level.) Values range between -24 and +24 semitones.!
!
Tip: Setting the delay time to the bare minimum, the feedback level to zero and the grain
frequency to a fairly low value effectively turns G-Delay into a real-time granular pitch shifter
whose pitch can be controlled via this knob.
Spray — Adds a progressive amount of randomness to the delay time of each individual
grain. The default setting of 0% adds no randomness, giving a perfectly clean delay signal,
and 100% gives the maximum amount of randomness, resulting in a chaotic “spray” of
sound.!
!
Tip: This control is great for completely disintegrating your audio signal on the fly.
Sync — Syncs the Left and Right delay times to the song’s tempo.
Mono — Links the Right channel’s delay time to the Left channels delay time, !
disabling Time R. Enabling this button will result in mono delay, whereas disabling it will create
a stereo delay (so long as Time L and Time R are set to different values).
