GETTING STARTED
*Note: BIAS Delay provides either True Bypass or Buffer
Bypass for you to choose from (please refer to the Bypass
Mode section of this manual for more information). If you
have a lengthy cable and a long signal path and want to
preserve high frequencies, Buffer Bypass will be most
suitable for your needs. On the other hand, if you want to
tone down the harsh top end of your sound, True Bypass
might fit your needs better.

FUNCTION AND OPERATION
1. Mono & Stereo
BIAS Delay comes with stereo inputs and outputs. With mono input (plugging into the left
channel only), BIAS Delay will duplicate the input signal on both channels so you can still get
stereo signal at BIAS Delay’s outputs. This is necessary in order to hear some of BIAS Delay’s
stereo effects properly. For example, the Ping Pong preset needs stereo outputs to produce its
alternating left and right panning effect.
If you also plug into the pedal’s right input, BIAS Delay will switch to stereo mode and process
left and right channels independently.
2. Engage & Bypass
When you first plug the power in, BIAS Delay pedal will be in Bypass Mode , meaning that the
input signal will be passed through the pedal without any modification from the presets’
processing. There are two different bypass types for BIAS Delay:
A. Buffer Bypass (System default) - - The signal will go through the buffer circuit and generate
a lower-impedance output signal. This allows the output signal to go through a much longer
cable without compromising high frequencies. In addition, Buffer Bypass can prevent the
common ‘pop’ noise you’d otherwise hear when engaging or disengaging a preset.
Hold down footswitch B and plug in the power to switch to Buffer Bypass mode.
B. True Bypass - This creates a short circuit between input and output to keep the bypassed
signal untouched as a high-impedance output signal. If you are using a cable longer than 18.5
feet while using this bypass mode, you might get volume loss in the high frequencies.
Hold down footswitch A and plug in the power to switch to True Bypass mode.
To engage a preset, press one of the A/B/C footswitches to turn on the effect. Press the same
footswitch again to switch back to bypass mode, or press another footswitch to switch to
another preset.
3. Save Preset
Once the preset is on, you can tweak any of the knobs on the control panel to modify its
sound. The preset LED will start to blink when you move a knob, indicating that the parameter
has changed.
Preset ON 1. tweak of the knob
2. LED start to blink
1. hold the preset knob
2. LED stop blinking
To save the parameter changes, hold the Preset knob until
the LED stops blinking.
To dismiss the changes, switch to another preset or switch
back to Bypass Mode.

4. Assign Footswitch
5. Note Subdivision
Each footswitch can turn on or off one of the 20 presets
assigned to it in the pedal.
To assign a different preset for a footswitch, just tweak the
Preset knob to switch to another preset. The footswitch
LED will start to blink. Hold the Preset knob until the LED
stops blinking, at which point the preset mapping will
update.
1. switch to other presets
2. LED start to blink
1. hold the preset knob
2. LED stop blinking
With Note Subdivision, you can customize the subdivision of delay (echo) time. In BIAS Delay,
there are 3 different (the most commonly used) note divisions on the control panel. With the
BIAS Pedal app, you can access many more subdivision options.
These are the note subdivisions available on the control panel:
・ Quarter note ・ Dotted 8th-note ・ 8th note triplet
The note division is affected by your BPM (beats per minute) and Tap Tempo settings in
establishing the delay time. Please refer to the Tap Tempo and BPM section immediately
below.
6. Tap Tempo and BPM
BIAS Delay comes with a Tap Tempo footswitch that allows you to quickly set the BPM value for
the delay effect. The time interval between your two taps represent a beat and sets the BPM*
value. To calculate the delay time, take the BPM value and multiply it by the ratio of the note
factor.
For example, when the NOTE is set to dotted 8th-note and you tap twice in 0.5 sec time:
2 taps / 0.5sec = 1 beat / 0.5 sec = 120 beats / 60 sec = 120 BPM
So, the delay time at 120 BPM using a dotted 8th-note = 60/(120x4/3)
= 0.375 sec for each echo
*BPM = Beats per minute

7. Expression Pedal
BIAS Delay supports expression pedals, allowing you continuously variable control of multiple
parameters at once while playing live onstage or in a recording studio. BIAS Delay can work
with expression pedals fitted with standard TRS jacks. The expression pedal’s range of control
over BIAS Delay’s parameters is calibrated by moving knobs on your BIAS Delay, as is
explained below:
・ Calibration
Value when exp. pedal in minimum position
1. Plug in an expression pedal with a TRS cable.
2. Engage the preset you want to control with the
expression pedal.
3. Hold down the Wireless button on the rear panel
to engage calibration mode. LED A will start to
blink. Set the expression pedal to its minimum
position and turn the pedal’s knobs to their
Value when exp. pedal in minimum position
minimum values. Press footswitch A to save the
minimum parameter values for the expression
pedal. Footswitch B will automatically start to
blink as you finish calibrating the expression
pedal with footswitch A.
4. Set the expression pedal to its maximum
position, and turn the pedal’s knobs to their
maximum values. Press footswitch B to save the
maximum parameter values for the expression
pedal.
5. Hold down the Wireless button to leave Calibration mode.
・ Control
Once you’re done calibrating, the parameters will change linearly between their minimum and
maximum values when you depress the expression pedal.
8. MIDI
BIAS Delay supports standard MIDI commands:
・ MIDI IN - This connector receives MIDI commands from an external MIDI device. Patch the
MIDI Out connector on the external MIDI device to the MIDI IN connector on BIAS Delay.
・ MIDI THRU - - BIAS Delay will send the MIDI command it receives at its MIDI In connector
out its MIDI THRU port. You can connect MIDI THRU to another MIDI device to receive the
command from BIAS Delay.
・ MIDI Channel
The default MIDI Channel number is 1. With the BIAS Pedal app, you can select the MIDI
channel from 1-16 or select Omni (in which case it will receive MIDI commands on all
channels).
