The full versions of the OP series plugins come with a huge collection of additional
soundbanks in fxb format that can be loaded by almoust every vst host as well as
Additional to this there are released new banks for free download on a regular base

An an owner of one of these plugins you will receive an email when there's an
update available. If you didn't receive a one this might be caused by the spam
filter of your mailserver, so also check your spam box.
But you now (except for OP-X Reaktor users) also can use the new login option

Because of the many requests for a detailed feature comparison between OP-X and
OP-X PRO we've set up a handy comparison table that gives a detailed overview:
It's however not necessary to decide on one of the two because you can get them both
for the price of OP-X PRO by buying OP-X first and get the OP-X PRO later just for
the remaining price difference. Use the "Upgrade from OP-X" for this on the purchase site.
The plugins are available for the windows VST interface (invented by Steinberg) and
support the vst 2.0 standard. The patches format is standard fxb/fxp. The plugins need a 32bit
environment to run. Supported operating systems: Win98, WinME, WinXP and Vista. The
plugins can't be run stand alone, they need a VST host to run. Windows Vista is still
not recommended because it takes too much ressources on its own and has some protection
mechanisms that can cause problems. Recommended is Windows XP.
If you nevertheless want to use Vista it's highly recommended to run your vst host
application in administrator mode. Otherwise Vista can block important write functions.
To set the default running mode to "administrator" right click on the application shortcut, choose
"Properties->Compatibility", check "Run as administrator" and save your settings.
Furthermore you should run the installer in administrator mode too. So instead of
doubleclicking simply rightclick on it and choose "run as administrator". The same
for uninstalling: Rightclick on the "Uninstaller" shortcut listed in the start menu
(Start->SonicProjects) and choose "Run as administrator.
If you want to use the plugins in a 64bit environment (64bit capable vst host within
XP or Vista 64bit) then you need to wrap the plugins with a 32bit vst host like
Another solution is to use a so called 64bit bridge. A recommended and tested one is
jBridge from J's stuff, which works well and is cheap. You can get it here:
You don't have a vst host? Here's a list of tested free vst hosts:
Free vst hosts
Because we simply can't test all possible combinations of operating systems and vst
hosts we ask you to test the plugins in your current configuration with the demo
versions before you buy.
OP-X is available in cross platform Reaktor 5 format.
Demo available here.
Native instruiments Reaktor5 is needed to run it.
NEW: Our flaghip product OP-X PRO-II now is available as native 32/64bit Mac plugin (AU, VST3) and too in native 64bit
for Windows (VST2, VST3)!
You can check the demo versions here.
All plugins exept the mini line ones are also available for Receptor. If you are
an owner of the pc plugins you can get free crossgrade on plugorama.
More about the Receptor versions in the following dedicated section.
The plugins are tested with Windows Vista 32bit and work without a problem. There are
however a few things you should pay attention to while installing or updating. As you
probably know, Windows Vista has quite strong protection mechanisms that can affect processes.
Before you install or update go sure you do this as administrator, which means you should
log in as administrator. Otherwise Vista can partly block the access to the registry or to other
important write functions on the disk.
If you start your sequencer and there's a message complaining about missing modules, then you've
probably not installed or updated with administrator rights. But there's an easy fix for it without
a new installation: Go to your vst instruments folder where you should find the SonicProjects plugins
folder. Apart from the plugin dlls you'll find a folder for each plugin containing a set of dat files in it.
Delete all these dat files in these folders, so that you'll have an empty folder in the end, then restart the
sequencer. The correct modules will be extracted now. Concerning Stringer it's not necessary because
this one is not affected. If so, then it's important to leave the big sample data file.
You also should run your VST host with administrator rights, otherwise Vista can block important
write functions and mess up the registry. Right click on the application shortcut, goto "Properties" and
then to "Compatibility". Here you should see a checkbox named "Run as administrator". Check this one
and save your settings. This is especially important for Ableton Live, which can produce a number of
strange issues (wrong registry entries, no extracted modules, crackling) when it's not run with
administrator rights. It's also recommended to run the installers and uninstallers as administrator
too (again by rightclicking and choosing "Run as administrator"). If you follow these hints there
won't be any issues in Windows Vista.
All plugins, exept the mini line, are too available for Receptor, which is
a state of the art hardware vst player. You can purchase here and get free
crossgrade to the receptorized installers on plugorama:

Plugarama offers specialized installers that are tested and fully supported by Muse Research,
including all additional banks. The standard pc versions and the receptor versions are
fully compatible, so you can profitate from the bank reloads published on the user area
sites (see article "Sound Reloads" on top).
The plugins have been reported to work in NI Kore. However Kore itself can't import
standard fxb banks by itself which is the format of all the additional banks
delivered with a full OP-X and OP-X PRO license. However there's a workaround for
this: You can use the free WVM from Wusik to import the banks. Here's the download
Download Wusik WVM
If you have a plugin with a whole library of FXB's, as it is the case with OP-X and OP-X PRO, you can
use Wusik VM inside of Kore to load an FXB, them import them as Kore Sounds. Only thing is, the plugin
will forever load inside Wusik VM in Kore, but there is really not a down-side to this. It has been
reported to work flawlessly with OP-X PRO.
V-Machine / V-Rack:
The standard versions of our plugins can be gotten to work with the help of wizard
files, but they don't offer sufficient performance and consume too much cpu power.
That's why we've built a custom made bundle with highly adapted versions of OP-X and
Stringer that went through a lot of optimization steps and offer a guaranteed and stable
performance in the V-Machine. The CPU consumtion has been reduced by about 40% to fit the
limited power of the V-Machine, e.g. by completely deactivating the GUI. So if you plan
to use OP-X and Stringer with the V-Machine it's highly recommended to get this bundle.
It will save you a lot of strenghts and sorrows, and offers a rock solid performance and easy
installation without wizard files. As a customer of our plugins you can get the bundle
for a cheap crossgrade price, starting at $10.

Apart from adapted versions of OP-X and Stringer the bundle also includes two effect plugins,
prepared ready-to-play banks in VFX format and a BCR2000 toolkit that offers a custom sysex
preset that fits the also included premapped versions of the banks. All presets (including effects)
can be played glitch free at a buffer size of 256 samples with no noticeable latency and a guaranteed
stable performance for critical live application.
A word about converters:
Digital systems only can sound as good as the digital-to-analog converters used
to get the sound out of the box. They can vary drastically in their quality, not
superficially, but when it comes to details, transparency, smoothness and clarity,
all aspects from which analog synthesis lives. That's why the quality of the converters
have a big impact on the sound of OP-X. Only a good set of converters will let all
the important details and depth come through. The most important part of a converter
is its sample clock. The more stable it is the better is the sound. The more jitter
there is, the more the signal is destroyed. The actual
converter chip is the cheapest part, today's budget soundcards often have the same
converter chips built in as the expensive high end devices. But they have a worse sample clock and an
inferior analog wiring. However, there's a trick to make even a cheap converter sound
much better: simply synchronize it with a quality external clock. You don't need a
word clock in, you can do it also over the standard inputs (sp/dif). The most cost
effective trick is buying an outdated upper class converter and use it as clock.
While the converter chips have become outdated compared to the specs of modern chips
the clock itself is still "high end". Of course there are also inexpensive single
clocks available, and also good value conveters or soundcards with a quality clock built
in. And if you beleive it or not: it makes a huge
difference. Virtual analog can only sound real analog if the signal is not being destroyed
on its way from the digital to the analog side of the system.
I'm new in the world of virtual instruments.
What do I need to run those plugins?
The virtual instruments we offer are in fact computer programs that use the cpu
of the computer to emulate a specific sound which is converted back to an analog
signal by a soundcard.
What you need to use the plugins:
A windows computer with Win98, WinME, WinXP or Vista installed (XP recommended).
CPU speed should not be slower than 1Ghz, the faster the better.
A so called "VST Host" which is a program that can load and play vst plugins.
There are a lot of free ones available, here's a list: recommended free vst hosts
An ASIO soundcard that allows for low latency performance (no delay while playing)
and midi connection. It also works with your built in audio device, but there will
be a delay then between striking a note and the audio output.
More infos here.
A midi keyboard. This can be a normal synth with midi output or a midi controller
keyboard. The midi output of this one will be connected to the midi input of your
soundcard which allows to play the plugin then like a real synth. Of course you can
also do without it and play the plugin using the mouse on the virtual keyboard.
