Frequently Asked Questions
How can I access the extended reverb engines without the app?
The extended reverb engines can be accessed via MIDI or USB-MIDI. Send a MIDI message CC #1 with
a value between 0 and 23. Values 0 to 11 correspond to engines Room (0) through Reverse (11).
Values 12 to 23 correspond to extended engines.
What kind of instruments can I connect to the Ventris’s inputs?
The Ventris’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 Ventris directly over USB, without using the 9 Volt supply?
No. USB provides 5 Volts, but the Ventris needs 9 Volts, so the Ventris cannot be powered directly
from USB. Make sure that you have plugged in the included 9V DC power supply when connecting to
the Ventris’s USB port.
When connecting the Ventris to a recording interface or mixer, should I used a Lo-Z
(microphone) or Hi-Z (line / instrument) input?
The Ventris’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 Ventris respond to MIDI messages being sent to it?
By default, the Ventris should respond to MIDI continuous controller messages on channel 1. The
Ventris’s MIDI channel can be configured using the Neuro Editors. 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:

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 Ventris is not responding to MIDI, make sure
that your MIDI controller is properly configured and sending messages in the format described above.
