7 - Synthesizer Basics
Proteus VX is a “Lite” version of our Proteus X2 and Emulator X2 products, and as such
it does not have all the capabilities of the full products. This chapter contains
background information on various programming aspects of synthesizers in general
and is also a “teaser” for the full Proteus X2 and Emulator X2 products. Proteus X2
provides full preset programming; Emulator X2 contains all features of Proteus X2 and
adds intelligent sampling and a host of powerful sample editing features.
Proteus VX uses the same sampling/synthesis engine and the same sound library as its
brethren and it sounds spectacular. The 16 controller knobs have been assigned to
control 16 basic parameters of each preset and using these controls, you can
completely reshape and transform the 1024 presets.
If you are new to synthesizers and electronic music, you may require more background
information than this manual provides. There are many books dedicated to synthesizer
basics and MIDI available through your local music dealer. Magazines such as
Keyboard and Electronic Musician, available at most newsstands, contain current infor-
mation on the subject, as well as valuable programming tips. The internet is a also a
rich source of information on this subject. Seek and you shall find.
Your initial involvement with the Proteus VX will most likely consist of playing the
existing bank and presets. While our factory presets are very good, there are probably
some things you would like to change, perhaps the LFO speed, the filter setting, or the
attack time. Eventually, you might want to make your own presets.
Editing Presets
It’s easy to create new presets by modifying the controller settings. This is really the best
way of getting acquainted with the Proteus VX. If you don't like the results, simply
reload the preset or bank and you'll be back to the original sound. The raw samples in
Proteus VX cannot be changed, so they’ll always be available.
To Edit a Preset
1. In the Tree, click on the Preset Icon of the preset you want to edit.
2. The Initial Controller Amounts are saved when you save the bank. Start here.
Adding Preset Effects
uses CPU cycles. If a
preset is used by multiple
MIDI channels and you
add Preset FX, the CPU
penalty is multiplied for
each channel that uses
the preset.
3. The Preset FX can be edited and saved with the bank.
4. The Preset Cords can also be edited. These cords are quite useful for controlling
the Preset FX via MIDI controllers. The available FX parameters depend on which
Preset FX you have selected.The Volume, Transpose and the Tuning Table can be
edited and saved.
• Note: The Poly Timer and Channel Ramp are NOT used in any of the Proteus X
Composer presets and so these controls have no effect on the sound.
Changes are not permanent until you SAVE a bank. Therefore, you can experiment all
you want with presets without worrying about losing a sound. Tip when Saving - Select
Save As… and use a different name to avoid overwriting the factory Proteus X
Composer bank.
