Ventris Dual Reverb Owner’s Manual

What kind of instruments can I connect to the Ventris
’s inputs?
The Ventris
’s audio inputs are high impedance (~ 1 M
Ω
) 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 b
e 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:
MIDI Channel
(Decimal)
1
2
3

5
6
7
8

12

14
15 16
CC Command Byte
(Hex)
B0 B1 B2 B3 B4 B5 B6 B7 B8 B9 BA BB BC BD BE 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 Ventris is not responding to MIDI, make
sure that your MIDI controller is properly configured and sending messages in the format described
above.
Can I use the Ventris
in my amp’s effects loo
p?
The Ventris
’s audio inputs can handle up to 8.76 dBu or 6.0 Volts peak
-to-peak, which allows it to
work
in most amp effects loops. Be sure to check your amp’s documentation to verify that the
maximum send level is less than the
Ventris’s
maximum input level.
