of one octave upward or downward.
Knob/Switch Parameter

sound.
TAP PITCH* Specifies the amount by which the pitch of the effect
sound will be shifted; an octave, a 4th, or a 5th. Each
time you press the switch, the setting will cycle
between -12, -7, -5, DT (Detune), +5, +7, +12, -12.
TAP+DEPTH PITCH* Specifies the amount by which the pitch of the effect
sound will be shifted in semitone units (100 cents).

8. FILTRON
This is an envelope-controlled filter (wah) that opens or closes a filter based on
input from a guitar.
Knob/Switch Parameter
DEPTH SENS* Adjusts the sensitivity to the guitar’s volume.
If this parameter is assigned to the expression pedal,
the cutoff frequency can be controlled by the expres-
sion pedal, and the openness of the filter will not be
affected by input from the guitar. (Using the knob will
adjust the cutoff frequency.)
TAP TYPE Specifies the direction of movement (up or down). If
Up is selected, the TAP switch LED will light up.

9. TAPE ECHO
This models an acclaimed analog tape echo. Originally, echo was created by a
tape head, and the delay time was specified by changing the speed of the
motor.
Knob/Switch Parameter
DEPTH LEVEL* Adjusts the mix amount of the delay sound.
If this parameter is assigned to the expression pedal,
the input level to the delay will be controlled by the
expression pedal.
TAP TIME Specifies the delay time in a range of 40...1048 ms.
TAP+DEPTH FEEDBACK* Adjusts the amount of feedback.
10. A.DELAY
This models an analog delay that uses a Bucket Brigade Device (BBD). Its
audio quality is lo-fi, but it is popular for its warm sound.
