The OP-X Free has got the same basic engine and sound as the full OP-X
while the available presets are limited to a few chosen ones and the GUI only
gives access to a few parameters. The OP-X Free can't load the patches and
banks of the full version and there's no vst automation or midi cc control.
However there's an extremely cheap way to get access to the complete OP-X
sound library and full automation: upgrade to „OP-X Player“!
OP-X Player has the same look as OP-X Free, but is able to load any OP-X
patch with identical sound as in OP-X. It comes with the full OP-X library (500
patches!) and there's automation and midi cc remote control.
If you also want to get access to all parameters and create your own sounds,
then you can upgrade again for a cheap price to the full OP-X, which gives
instant access to all 83 parameters on a huge and classy interface. All these
parameters can be automated and remote controlled with midi CC.
Separate Voice Design (SVD):
The technical structure of this synth ist quite unique. The enigine is based on
six totally independent voices which correspond to the voice boards of the
original godfather. There's no voice cloning to achieve polyphony as it is
normally the case in VST instruments. Each voice is a separate mono synth
with completely independent signal path and slightly different sound as it is the
case too in real analog polysynths.These imperfectnesses are one of the main
reasons for the organic and lively character of the old faithfull original.
The original only offered an „Auto Tune“ function which tuned the oscillators of
the voice boards. The warm up drift did detune the oscillators again after some
time and the „Auto Tune“ had to be repeated. When filters and envelopes were
detuned, then they had to be tuned with a screwdriver in the inside of the
device by tweaking a lot of trimpots on the voice boards.
The OP-X makes this easier. It offers four global buttons which let you tune or
again detune oscillators, filters, filter envelopes and portamento times on the
fly. The oscillators' tuning additionally can be altered contunuously with the
„spread“ knob which also works in polyphonic mode. Everything can be mixed
up in any combination of course. So there are a lot of options to achieve the
right sound with the wished amount of analog dirt.
The filters of OP-X are meticulously modeled after the legendary analog
counterparts which never sound thin even in high resonance settings. Those
filters are unbeatable for lively and fat sweeps and pads.
Doubleclick the installer and follow the instructions.
The installer will search for the shared vst plugins folder. You can also browse
your computer for the vst plugins folder manually. The plugin will be installed in
a subfolder named „SonicProjects“.
The installer will also create a folder named „SonicProjects“ in your start menu.
You will find here the pdf manual and the uninstaller.
Note: You will need a vst host to run the plugin. Have a look at the „Hosting“
section right below for further information.
Remove the plugin:
Use the uninstaller in the „SonicProjects“ folder in the start menu.
License and copyright
The OP-X Free is free and can be shared without any limitations. It's not
allowed however to make any changements, involve it in other software
projects or make money by selling it. It's allowed however to use it in
commercial music productions and live events. All rights are owned by
SonicProjects.
Hosting
The OP-X Free can't be run in standalone mode. It needs a vst host to run. If
you don't have a one then have a look at our dedicated site where we have
listed some tested and recommended free vst hosts including short guides and
a lot of additional information:

The voice LEDs
These LEDs indicate voice activity. Each voice has its propriate LED. That
means, when a voice is receiving trigger data to play, its propriate LED shines.
In unisono mode, all six LEDs are glowing at the same time. The original has
this LEDs too, but mounted on the individual voice boards in the inside of the
device. With their help, you could see that a voice was working correctly.
The TUNER section:
VOLUME
Master volume. Its setting is stored with the preset.
TUNER
The individually and slightly detuned voices can be tuned here. Read the intro
for comprehensive info on the voice tuning.
OSC
Tunes the oscillators. In released state, each voice is slightly and individually
detuned as it would be on startup in the original.
FILT
Tunes the filters. In released state, the filter cutoff of every voice is slightly
different, as it is the case in every original device that is not freshly serviced.
ENV
Tunes the attack and decay times of the filter envelopes. In released mode,
the attack and release time of every voices' filter envelope is slightly different.
This gives organic life to pad and sweep sounds.
A further tunable parameter are the portamento times.
The portamento times can be tuned in the „CONTROL“ section, see below.
The CONTROL section
PORTAMENTO
Also called "glide" sometimes. Makes the pitch change continuosly between
the notes. Short settings in unisono sounds makes the sound "squeak". The
function also works in polyphonic mode. The portamento can be detuned with
"Porta DET" in the additional functions section (beyond filters section). In
released "Porta DET" mode, the portamento times of each voice are equal. In
pushed mode the times vary from voice to voice which was typical for the
original. The sonic result in solo sound is a special sort of "depth" while gliding.
DET
Portamento tuner. In released mode, the portamento times of each voice are
equal for snappy "squeek". In pressed mode, the times vary slightly from voice
to voice which was typical in the original. The sonic result in solo sound is a
special sort of "depth" or „smear“ while gliding.
The FILTER / MANUAL section
A specially designed 12db Filter tries to do its best to emulate the famous SEM
sound. The SEM filters got famous with the beige SEM-Modules and the SEM
based Four- and Eightvoice. The OB-X was the last Ob. synth that was
equipped with this discrete design. Later models, beginning with the OB-Xa,
got the standard Curtis Chips. One of the special things of the SEM filters is
that in high resonance settings the sound remains as fat as in zero resonance
settings. This is a wonderful thing for pads and sweeps. The old SEM filters
had no self oscillation, so you won't find it here too.
CUTOFF
Regulates the filter cutoff frequency.
SPREAD
Spreads the oscillator tuning of the voices - good for fattening up unisono
sounds, but it also works in polyphonic mode for continuously controlled
detuning of the oscillators to emulate slightly „pissed-off“ tuning.
The VOICE PANS section
The voice pans:
This was a very popular feature amongst old analog synths. In contrast to
many old synths, the controls can be accessed on the surface and also can be
stored with the preset. The panpots can also be automated. In the original
device, these pots were on a board in the inner device. The voice pans allow to
place each voice independently in the stereo field.
The individual pan trimpots from the left to the right correspond to the voices 1
to 6 whose activity is shown with the corresponding voice LEDs (see above).
The LEVERS section
A - Animation
The keyboard and the levers of the OP-X react to the computer mouse. They
also react to midi data. The keyboard response to midi data can be switched
off with the A (Animation) button.
The midi data response of the keyboard can cause interference noises in
some situations, especially in stacked solo sounds. Switch off the keyboard
midi response (top button) in that case.
L - Legato
The lower L button switches on and off legato mode for unisino patches. In
legato mode the pitch returns to the hold note and notes are only retriggered
when all keys are released like in old analog polysynths. In released mode
notes are retriggered everytime which can be more suitable for bass sounds in
unisono mode.
A speciality of old ob synths was that they had two vertically working levers
instead of the popular wheels invented by moog. The modulation lever is on
the left side. In the original it only worked downwise. In the OP-X, it can be
used up- or downwise. Upwise, the modulation is inverted (hearable only in a
realtive time context). The pitch lever is on the right side. It reacts vice versa
than a popular wheel. Downwise movement highers pitch, upwise movement
lowers pich.
Os2
Oscillator 2 only. When switched on, the pitchwheel (or whatever it is called)
does change the pitch of oscillator 2 only. This is great for controlling sync
sounds. Try the preset "SyncSolo Wheel" to explore this.
+12
This button serves for switching the pitchwheel interval from a third (standard)
to an octave (12 semitones).
Oct.
Switches the keyboard octave (three octave range). Be careful handling it in
vst automation mode because of the "radio button" switch mode.
Tun.
Master tune. This trimpot lets you adjust the master tuning of the synth to fit
acoustic instruments with deviating tuning.
Why six voices?
The original godfather of this project has six voices too. The original could be
purchased with 4, 6 or 8 voices. Every device had sockets for eight voice
boards. So the voices could be expanded by mounting further voiceboards.
The OP-X Free is built almoust exactly the same as the real analog original, so
there's a limited number of individual and comletely independent voices with
slightly different but tunable sound instead of a lot of digitally cloned ones. The
result is a rich and orgainic sound.
VST automation
OP-X FREE does not provide vst automation. Upgrade to OP-X PLAYER
using the „Get More Sounds“ button to make this feature available. With vst
automation you will be able to record and play back the movements of all
available knobs and buttons. So you can e.g. automate the cutoff knob for
tremendous filter performances.
MIDI CC Implementation
This feature is not available in the OP-X FREE. Upgrade to OP-X PLAYER
using the „Get More Sounds“ button to make this feature available. OP-X
PLAYER will let you remote control all knobs and buttons using midi cc
messages. The implementation follows the popular Pro53 standard which
means you can load this preset and all important parameters (e.g. filter cutoff)
will already be ready to tweak.
While the OP-X Free and OP-X Player only give access to a few chosen
parameters, the full version allows Midi Remote Control for all 83 parameters
with CC numbers leant on the popular Pro53 standard.
