Two Notes VB-101 - Manual (Page 17)

Quick start guide
The miking is achieved in 3 steps with the TORPEDO VB-101:
1. Choose a power amplifier (or switch it off if you are using a loadbox), a speaker cabinet, and a
microphone (Power Amp, Speaker, and Microphone sections);
2. Position the microphone inside the virtual studio (Miking window and parameters);
3. Shape the signal (Low Cut, EQ, Exciter, Comp, and Spatial sections).
At each step, Two Notes Audio Engineering implements its know-how to offer the most advanced
simulations on the market and ensure absolutely realistic quality both for the musician (in terms of
playing sensation) and for the listener (in terms of sound quality).
You can embed up to 50 Two Notes cabinets in the TORPEDO VB-101. Download the free TORPEDO
Remote software (Mac OSX and Windows PC) from the Two Notes website , and you will be able to
add or remove the embedded cabinets. There are currently 45 Two Notes cabinets available, and
new free cabinets will regularly be released to you through your TORPEDO Remote software.
4.1 Tube Stage Output
When they are using guitar/bass preamplifiers with some other speaker emulators, guitarists and
bassists may feel they miss a power amplifier’s contribution to the overall sonic texture. Many musi-
cians get their sound from some particular use of that element and the TORPEDO VB-101 gives you
the possibility to use it too.
To that effect, Two Notes Audio Engineering has developed an original tube-stage modeling that
gives you a choice of 4 different tube models (6L6, EL34, EL84 and KT88) in Push-Pull (PP) in AB class, or
Single Ended (SE) in A class configurations. You can push this tube stage like a conventional amplifier
and look for that subtle yet particular distortion.
The TORPEDO VB-101 can be used as a super-DI for keyboards. The tube-amp simulation feature,
developed for guitarists and bassists, can also be a very interesting device to warm up the sound of
a synthesizer, an organ, or a digital piano.
4.2 The Torpedo technology, convolution and Impulse Responses
The Impulse Response (IR) of a given system consists in the description of that system’s behavior
in the form of a very detailed filter. The convolution technique uses IRs to simulate the behavior of
specific systems, such as reverbs, speakers, EQ, and so on.
This is the most accurate method to simulate sound signatures that are linear (i.e. without distor-
tion) and time-invariant (i.e. with no effect such as modulation, compression, hysteresis, etc.). It is
particularly well suited for speaker miking simulation.
Two Notes has developed a unique technology based on an adaptation of convolution
techniques. Starting with a measure of a real cabinet + microphone setup, the TORPEDO
VB-101 can accurately reproduce the system as it was measured, including its distortion,
as well as the microphone’s position in space by using IR synthesis. Control the amount of
distortion produced in the loudspeakers (Overload) and fix any phase issue with the Variphi
— those are exclusive Two Notes Speaker Response (TSR) functions.
