If you select Envelope Follower as a modulation
type, the Mod Rate slider changes to a Mod
Slewing slider, which is adjustable from 0% to
100%.
Output Meter
The Output Meter indicates the output level of
the processed signal. Note that this meter indi-
cates the output level of the signal—not the in-
put level. If this meter clips, the signal may have
clipped on input before it reached Sci-Fi. Moni-
tor your send or insert signal levels closely to
prevent this from happening.
Recti-Fi
Recti-Fi provides additive synthesis effects
through waveform rectification. Recti-Fi multi-
plies the harmonic content of an audio track
and adds subharmonic or superharmonic tones.
Recti-Fi Controls
Pre-Filter
The Pre-Filter filters out high frequencies in an
audio signal prior to rectification. This is desir-
able because the rectification process can cause
instability in waveform output—particularly in
the case of high-frequency audio signals. Filter-
ing out these higher frequencies prior to rectifi-
cation can improve waveform stability and the
quality of the rectification effect. If you wish to
create classic subharmonic synthesis effects, set
the Pre-Filter and Post-Filter to a relatively low
frequency, such as 250 Hz.
The range of the Pre-Filter is from 43 Hz to
21 kHz, with a maximum value of Thru (which
effectively means bypass).
Rectification
Positive Rectification
This rectifies the waveform so that its phase is
100% positive. The audible effect is a doubling
of the audio signal’s frequency.
Negative Rectification
This rectifies the waveform so that its phase is
100% negative. The audible effect is a doubling
of the audio signal’s frequency.
