necessary.
Frequently Asked Questions
How do I change the routing mode for my pedal without changing anything about the
sounds?
 Connect the Neuro App cable and go to the Sound Editor in the app.
 Flip the toggle switch on the hardware to the left position.
 In the app, go to the I/O Routing Option (bottom of the list), select it, and the desired routing
mode. Then tap Done. You should see the Control LED blink when the message is received.
 Tap the Burn button. This opens a menu for burning locations.
 Select "Toggle Switch Left". This burns any changes you made into memory. Since you only
changed the I/O Routing mode, that will be the only thing that is changed. The rest of the
parameters for that sound will remain unchanged.
 Repeat these steps for the middle switch position and the right switch position.
What kind of instruments can I connect to the Mercury’s inputs?
The Mercury’s audio inputs are high impedance (~ 1 MΩ) and they can accept high impedance signal
sources like guitars/basses with passive pickups, as well as low impedance sources like line-level
audio circuits, guitars/basses with active pickups, electronic keyboards, or mixer outputs. The input
circuit can handle signals ranging up to 5.6 Volts, peak-to-peak.
Can I power the Mercury directly over USB, without using the 9 Volt supply?
No. USB provides 5 Volts, but the Mercury needs 9 Volts, so the Mercury cannot be powered directly
from USB. Make sure that you have plugged in the included 9V DC power supply when connecting to
the Mercury’s USB port.
When connecting the Mercury to a recording interface or mixer, should I used a Lo-Z
(microphone) or Hi-Z (line / instrument) input?
The Mercury’s output will be low impedance when the effect is active or in buffered bypass mode,
but it will be high impedance when using true bypass mode and a guitar with passive pickups.
Therefore, it is recommended that you use a high impedance (Hi-Z) input on your recording interface
or mixer to avoid signal loss.
Why doesn’t the Mercury respond to MIDI messages being sent to it?
By default, the Mercury should respond to MIDI continuous controller messages on channel 1 (in
technical terms, this means that the lower 4 bits in the command byte of MIDI messages should be
0000 in binary or 0 in hexadecimal). The Mercury’s MIDI channel can be configured using the Neuro
