Wah Pedal
The Wah Pedal plug-in simulates “wah-wah” pedals used by
guitarists, bassists and keyboard players.
Pedal Position: the position of the rocker pedal in percent of
forward sweep. This can be adjusted with the Pedal Position
knob, or by clicking the rocker pedal and dragging up or
down.
Sweep Start: the starting position of the pedal relative to the
full range of the pedal’s sweep.
Sweep Range: specifies the sweep range as a percent of the
distance from the sweep starting position to the end
position.
Sweep Exponent: defines the curvature of the sweep
response over the sweep range. This greatly affects the “feel”
of the pedal. Most wah pedals use a negative exponent.
Character: controls the relative amount of distortion, with
zero being perfectly linear. Classic wah-wah pedals are
discrete designs that use feedback, but the simplicity of the
circuit allows some weak low-order harmonic distortion to
find its way to the output.
Voi c i n g : selects the frequency response model. “V846”
represents a vintage ‘70s Vox 846™, “WhineBaby” a modern
Dunlop CryBaby™.
Sweep Mode (stereo only): chooses which channels are in
phase with the effect: left, right or both. For the out-of-phase
channel, the pedal position is inverted after applying the
sweep range modifications but before the sweep curvature is
applied to simulate playing an identical pedal that is “turned
around.”
Sweep Control: selects whether automation ramp data or
MIDI continuous controller (CC) messages should be used
to automate the pedal position and effect bypass.
When MIDI is chosen, any ramp data in the track is
overridden, and the pedal position knob and pedal graphic
do not affect the pedal position value.
Pedal CC: selects the MIDI continuous controller (CC)
number assigned to the pedal.
Bypass CC: selects the MIDI continuous controller (CC)
number assigned the bypass switch. Values 63 and higher
will bypass the effect.
AUDIO UNIT INSTRUMENT SIDECHAIN INPUTS
Sidechain inputs are now supported on Audio Unit (AU)
virtual instrument plug-ins as well as MAS instrument plug-
ins.
WAVE64
The Wave64 extension to the Broadcast WAVE file format
allows for audio files larger than 4 GB. If you anticipate
creating audio files larger than 4 GB, choose the Broadcast
WAV E fi l e f o r m a t .
☛ How quickly you create a 4 GB file depends on the
channelization, sample rate, and sample format. When
recording as an interleaved stereo 16 bit 44.1 kHz file, it takes
about 6.7 hours to create a 4 GB file, but only about 7 minutes
when recording as an interleaved 10.2 surround 32 bit
floating point 192 kHz file.
When using Broadcast WAVE, if a file will be smaller than
4 GB at the end of an audio recording pass, the resulting file
will be a regular Broadcast WAVE file. If the resulting file will
be larger than 4 GB, it will use the industry standard Wave64
extension to the Broadcast WAVE file format.
