Frequently Asked Questions
What kind of instruments can I connect to the Nemesis’s inputs?
The Nemesis’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 6.0 Volts, peak-to-peak.
Can I power the Nemesis directly over USB, without using the 9 Volt supply?
No. USB provides 5 Volts, but the Nemesis needs 9 Volts, so the Nemesis cannot be powered directly
from USB. Make sure that you have plugged in the included 9V DC power supply when connecting to
the Nemesis’s USB port.
When connecting the Nemesis to a recording interface or mixer, should I used a Lo-Z
(microphone) or Hi-Z (line / instrument) input?
The Nemesis’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 Nemesis respond to MIDI messages being sent to it?
By default, the Nemesis 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 Nemesis’s MIDI channel can be configured using the Neuro
App. Channel numbers in MIDI use zero-based counting, so MIDI channel 1 is described as 0 in
hexadecimal, MIDI channel 2 is described as 1 in hexadecimal, and so on, concluding with MIDI
channel 16, which is described as F in hexadecimal. A continuous controller message starts with a
hexadecimal B and is followed by the channel number (0 through F).
So, the command byte from your MIDI controller should be formatted as shown in the following
table:

B9

BB

BF
Each continuous controller command byte is followed by two bytes, the CC number and the value. So,
each CC message consists of a total of three bytes. If the Nemesis is not responding to MIDI, make
sure that your MIDI controller is properly configured and sending messages in the format described
above.
