Auto Wah
Auto Wah is a dynamic ilter, similar to a Wah Wah pedal. A Wah Wah pedal has a
'rocker' footplate to control the frequency at which the ilter operates. Auto Wah has
no 'rocker' footplate, so in ENV Mode the rocker automation responds to input level.
In LFO Mode the rocker motion is fully automated. Auto Wah's editable parameters
are:
PARAMETER VALUE RANGE DESCRIPTION
Mode ENV & LFO Envelope Filter & Low Frequency Oscillator.
Frequency 0 - 10 Controls the resting frequency, or fully closed posi-
tion, of the Wah, thereby setting how far the ilter
opens when playing.
Sensitivity 0 - 10 ENV Mode: Controls how much the Wah opens in
relation to the pick attack.
LFO Mode: Controls the speed at which the Wah
opens and closes. Set to zero and Auto Wah acts as a
ixed rocker Wah.
Resonance 0 - 10 Adjusts the magnitude, bandwidth and shape of the
ilter's resonant peak.
Pitch Shifter
Pitch Shifter generates chromatic harmonies with the ability to ine tune. This
enables you to pitch up or down to produce octaves or 3rd, 4th or 5th harmonies.
Pitch Shifter can also produce more discordant, quirkier sounds. Pitch Shifter's
editable parameters are:
PARAMETER VALUE RANGE DESCRIPTION
Semitone -12 to +12 Selects the pitch of the generated note chromatically
from an octave below to an octave above the note
played.
Fine Tune -50 to +50 Fine tunes the pitch of the generated note.
Regeneration 0 - 10 Adjusts the percentage of the signal fed back into the
Pitch Shifter. Set to zero for a single pitch shifted tone.
0 - 10 Adjusts the balance between the guitar signal and the
Mix generated note.

16. AMP AMP is short for preamp. MST modelling faithfully recreates classic and modern Marshall
valve tones as well as other famous valve amp tones. Each AMP model creates an authentic
preamp setting. The MST preamp models are classiied into three groups: Clean, Crunch &
Overdrive.
Your CODE ampliier's MST preamp models are:

NATURAL
The Natural preamp is designed to be used with external FX without the tonal
colour of an MST modelled preamp. It provides EQ for tonal shaping and access
to the Gate.
If the noise Gate is applied, when your sound level drops below the set threshold
it will activate, preventing any signal below that threshold from passing through.
It progressively attenuates the guitar signal, following its dynamics, to suppress
unwanted noise.
PARAMETER VALUE RANGE DESCRIPTION
Threshold 0 - 10 Sets the point at which the Gate begins to close.
