Proteus VX Question & Answer
The Controller knobs on my keyboard don’t work with Proteus VX
A The controller numbers sent by your MIDI keyboard must match the controller
numbers that Proteus VX is receiving. See “
MIDI Channels & Real-time Controls”
on page 117. Also see “Controllers”on page 22 to change the MIDI controllers
that Proteus VX receives.
There is a huge delay when I play Proteus VX from a MIDI keyboard
A Lower the ASIO Buffer Latency setting on your host application. An ASIO Buffer
setting of 10ms or below will be acceptable for most players.
Parts are cutting out in my sequence
A#1: You may be exceeding the capacity of your computer’s CPU. When multi-
tracking using VSTi’s and VST effects, it might be a good idea to “Render” or
“Freeze” the tracks to free up CPU resources.
A#2: You might try increasing the CPU Cap parameter in the Preferences menu
(
page 19). This setting controls the amount of CPU resources that Proteus VX is
allowed to use.
A#3: Turning Ultra High Interpolation Off in the Preferences menu frees up
CPU resources at the expense of audio quality. Use your ears to decide.
A#4: Are you running multiple instances of Proteus VX? Don’t. Proteus VX was
designed to be run as a single instance using multiple MIDI channels. Running
more than one instance of VX is extremely wasteful of your CPU resources.
Can I play SoundFonts with the Proteus VX?
A No, but the full versions of Proteus X2 (and Emulator X2) include a File Converter
program which converts SoundFonts to the Emulator format used by Proteus VX.
Can I play General MIDI files using the Proteus VX?
A No, but the full versions of Proteus X2 (and Emulator X2) include a General MIDI
bank. This bank will load into Proteus VX.
Can I send different MIDI channels to separate outputs?
A Yes. The VST Output Bus setting (page 20
), lets you add additional VST buses.
After additional buses are created, Proteus VX channel outputs can be assigned
to VST buses in the Multisetup, Output field.
How do I find out the number of samples used per note?
A Play a single note on the keyboard and look at the “Samples Playing” display at
the bottom of the window. Please refer to the diagram on page 28
.
