New features and changes compared to OP-X PRO-II:

Quick comparison: comparison table

Interface: - A completely re-organized logically structured interface which bunches related controls together in clearly outlined function groups

- No more hidden functions and mapped parameters using un-mapping tricks to create separate controls or clearly show options

- The seamless tuning options formerly done by clicking a label above a button and dragging the mouse vertically (as e.g. for seamless autotune or seamless osc levels) now offer dedicated visible trimpots

- As a small "convenience"-change to make things more logical and coherent, the tune/autotune button/seamless control for portamento now works not inverted anymore. So activated means tuned (applied auto-tune) and not de-tuned.

- The panning modulation knob now also offers a quick-reset-button to immediatly switch panning modulation off if needed

- Despite these massive changes these tricks allow for full direct former patches compatibility and allowed to furtermore seamlessly use the huge existing sound-library

- The synth even is backward compatible for the "old" common parameters. The new parameters simply won't have an effect back in OP-X PRO-II. The only exception is the settings for the pitchbend and modulation wheels which now doesn't use presets anymore but is being converted to separtate split parameters which won't convert backwards (so you have to set the pitchend/ modwheel preset manually) and the displayed patch name which isn't a separate parameter here anymore but linked to the file name. So you had to set this one manually too sometimes. But we guess porting patches back to OP-X PRO-II won't really be your main goal...

- While OP-X PRO-II already had a huge parameter count (142 parameters in total) the new synth now has an almost unbelievable number of 199 parameters without the need of a patches format transition since we originally designed the format for future upgrade by spending it a maximum number of 256 parameters

- Despite this immense number of parameters the synth still is a one-page synth except for the very rarely used filter-envelope-trimpots which aren't anymore on the main interface but can be found on a new "Boards" page which shows the inner synth structure based on 12 separate voice boards, and the new Matrix-Modulation section which can be opened in the LFOs section and so just covers the controls for LFO1 (main LFO) and LFO2 (lever LFO)

Patch-Browser:

- A completely re-worked much easier to use patch-browser which only uses single presets and no banks anymore, but still can emulate banks by grouping presets in folders of up to 128 presets per folder which appear as directly choosable category on the left. Apart from the standard bank folders there are also four special purpose folders below "---user---" which offer a category menu on the right and allow to search for categories or set categories either globally (3_FAVOURITES and 3_SEARCH) or local (2_SAVED and 3_RELOAD). Furthermore you can turn any folder into a category folder which can contain more than 128 presets by including "_EE_" in its name.

- This allows to immediatly access up to 16'384 presets within seconds without the need of loading banks and also allows to search patches by categories (sound type) locally or globally since all more than 5'000 preset files (about 3'000 unique presets, some in more than one bank) are pre-categorized!

- The synth is directly compatible to all former OP-X PRO-II presets (so still uses the existing .opxpreset format) and since it uses no banks anymore allows to import OP-X PRO-II banks (.opxbank) which after importing automatically creates a folder by default named the same as the imported bank and with all its included presets saved in the same order as single presets within this folder. The original order is preserved by adding order prefixes (#001 #002 #003 etc. followed by a space) which then later on are being hidden both in the preset list and in the preset name field

- This auto-detect prefix trick also would allow you to (manually) bring a set of presets in any wished order if you wish to have a different order than the two avalilable as standard, which are alphabetic and sorted by saving date (upon activating the RFR button in the top-bar)

- The mentioned RFR (=refresh) button in the synth's top-bar does several things at once: First on it on each click refreshes the folders list on the left in case you manually created a new folder. Dependent on the chosen folder it additionally does some other things: In 2_SAVED it sorts presets by save date (newest on top) instead of the standard alphabetical order. This helps to trace which preset was saved as the last. In a normal bank folder that contains no factory presets (detected by ordering prefix #001 etc. of the first preset) it also sorts the presets by save date, but the newest at the end. In 3_SEARCH it makes the name field at the top left show the preset's original folder instead of the preset name. In 3_FAVOURITES it does the same and additionally hides the prefix-dots of the famous patches list if you visually prefer this.

- Of course you don't need to import any of the former factory and reload banks since these alltogether already are imported and available on installation. The base banks from the root area of the OP-X PRO-II pre-installed banks library have the prefix "B_" (for "Base"), the banks from the "Downloaded" folder (including ALL reloads fro the banks reload site) the prefix "D_" (for "Downloaded") and the banks from the "Extrabanks" folder the prefix "E_". So you only still need to import your own custom banks if you should have such banks. Single presets can be placed and used directly without any importing/conversion by simply putting them in a newly created folder within the folders section and hit (and again de-activate for standard alphabetical order) the RFR button on top in order the new folder is being listed

- One folder should not contain more than 128 presets since the right pane of the patch browser only can show a maximum of 128 presets. This on one hand is to avoid the need for annoying scrolling, and on the other hand is needed to preserve the MIDI standard of a maximum of 128 presets for a bank in order the program change via MIDI CC feature (kept from OP-X PRO-II) still works

- The patch name both shown in the patch list and in the patch-name-field on top no longer is an own independent parameter but is the same as the file save name (minus the order prefix #001 etc. if this is used) which also is more common

- Saving presets: Clicking on the SAVE button saves the preset into the dedicated 2_SAVED folder by default. The default save file name is the same as the name shown in the name field at the top left, but also still can be changed in the save file dialogue. To keep the save name as short that it fits the preset name field it's recommended to type in the new name in the name field (confirm by hitting enter) prior to saving. In OP-X PRO-3 the shown preset name in the name field now isn't an independent parameter anymore but is the same as the save file name. You later on also can set a category for each saved file by clicking on SET in the menu on the right which will list all not yet categorized presets in this folder. To set a category choose a category on the right and then click on SAVE. The tagged preset then will disappear from the SET list. The RFR button on top sorts the saved presets by save date (newest on top - standard is alphabetical) which can be handy to trace the last saved preset.

- Mark favourites: To mark a preset as favourite click the FAVO button on top. In presets view this adds a .dot in front of the preset name. To un-favour again simply click the button once more. The presets that were marked as favourite will be listed then in the 3_FAVOURITES folder which also allows to filter by category which helps to target presets once you have many favourites. Listing initially is slow since more than 5'000 preset files have to be scanned. But from then on it will be faster since the search result is kept in RAM. After setting a favourite it will have to re-scan again, so the first launch of the favourite folder then again will be slow. From then on again faster. To remove a favourite from the favourites list either click on DEL or FAVO. Clicking RFR on top shows the favourite's original folder name instead of the preset name and at the same time makes the dots disappear if you prefer this visually.

- SEARCH: The 3_SEARCH folder triggers a global search function and lets you list all patches from all folders (more than 5'000) and filter by category if needed. After initial folder choosing and also after switching categories you can type in a search term in the name field to find a specific preset within the chosen category or in all presets. SET lists all not yet categorized presets found in the entire library.

- 3_RELOADS is dedicated to put new presets released by SonicProjects - DEL deletes a chosen preset. But it deletes is savely, which means it's not irretrievably erased but thrown into the trash bin of your system and so later on still could be recovered

- There's no rename function, but to rename a patch simply again save it with a new name and then delete the old one

- The patch-change-smoother now not only applies to patch changes via increment/decrement buttons and MIDI CC program change but also to manually picking presets in the list. Patch-change smoother means that before switching a patch the audio quicly fades of, all notes are realsed, only then the patch is switched, and then audio is faded in again. So you now have smooth artrefact-free patch change operation all accross the field

Synth-Engine:

- Improved very smooth sound quality (max CPU version only) without sacrificing the typical warm and full signature-sound and character of the synth and without increasing the CPU use by very far so that the synth still is light on CPU measured by its awesome sound! The ECO and LC versions offer the 100% original sound and use less CPU.

- An added brightess mode "Max" (max CPU version only) which allows the synth to get even brighter than the previous maximum brightness mode "brilliant" if needed

- 2 new added filter types: "24db" = fully 24db with OB character (the OP-X PRO-II 24db mode in fact wasn't fully 24db), and MG = moogue type 24db with less bass amount in high resonance setting) both with and without filter self-oscillation. The previous 24dB mode of OP-X PRO-II is named "Hard" here. So there's a total of none less than 7 filter types now (LP 12db, LP Hard, LP 24dB, LP MG, High Pass, Band Pass, Notch), if you count the added self-oscillation as additional mode even 10 filter types! And this all offering seamless transition / mixing between LP (12db/Hard/Hard SO,24dB, 24dB SO,MG, MG SO) and multimode (HP,BP,NO) and even seamless transition between the multimode modes! Not to stop with this, apart from the fixed-mapped modulation of the filter mix by LFO1 or filter envelope you can freely modulate both in the new mod-matrix (more to this one later)!

- Effects-Section: An added preset-based awesome sounding modulation unit (so no parameters/fixed modes) already heavily beloved in our Stringer plugin which offers Chorus, Double-Chorus (CE1), Flanger, Chorus-Flanger, Phaser, and finally 5 different Ensemble effect types (ENS, ENS1, ENS2, ENS3, ENS4) from which 3 were direcly modeled after the original circuit of the ARP Solina!

- Envelopes-section: An added dedicated fully independent pitch-envelope (voice based, so times 12). That's however not all since the matrix modulation section (see later) offers another 2 envelopes (one polyphonic, one monophonic) which adds up to a total of 5 envelope generators!

- Main LFO: An added fastly accesssible key-tracking trimpot for pulse with modulation in order to make the depth of pulse with modulation depend on the key pitch - which allows to tame the overly deep modulation impression in lower key registers if needed. But this only is the hard-wired direct way on the standard synth-interface. This all and much more of course also can be done in the new modulation matrix! See later. Regarding modulatuon matrix, this section also will offer two additional LFOs (one global, one voice-based, so times 12) which together with the lever LFO adds up to a total of 4 LFOS!

- Unisono: The legato-mode (LEG) now not only offers last note priority (as it's the case in OP-X PRO-II) but on demand also lowest note and highest note priority. Standard (La/Lo/H button deactivated) still is last which in our opinion ist the most widly useable. But now you have all options if needed. - Aftertouch: The aftertouch input (key pressure) now is smoothed so that you won't hear stepping even when the used controller only has a low aftertouch reslolution. This especially makes aftertouch filter cutoff (so open the filter by key pressure) sound much smoother and better

- The "Boards" page now offers a little button that activates voice reset on song start - which means that upon song start the voices always are reset to voice 1 / all voices cleared, so that - if you like - always have the exact same start situation regarding voices on song start. This can be important if you use a lot of voice-based detunings or even detunings in a pitched melody effect (filter in high resonance setting) which cycles through the voices. Without a reset on song start you'll always have a different random starting point within the voices (since allocation is rotating). With activated reset this will be always the same/starting at voice 1. You also can manually reset the voices on the fly anytime using the small "Manual Reset" button

- The "Levers" section (or better said section for settings for pitch-wheel and modulation wheel) now no longer uses 32 presets but splits the settings for pitch-wheel and modulation-wheel to separate parameters using software based conversion. This allows you now to set the interval or mode separatly for pitchbend up, pitchbend down and modulation wheel by clicking into the dedicated square field which toggles through the available modes. To quickly set the pitchbend interval the same for both up and down you can grab the little trimpot. To quickly switch between the two most common modes 2 semitones Up/down and one octave up/down you can use the square button below. The individually clickable intervals/modes for both pitchbend up and down are: 1 - 12 semitones (12 only comes at the very end), 2 octaves, 3 octaves 4 octaves and vibrato (M). For the modulation wheel it's vibrato (M), filter (F), 2 (2 semitone up) and new 12 (12 semitones up for oscillator 2 only - e.g. suitable to control sync sounds). These however are only the quickly accessible fixed modes! The new matrix modulation section (see below) now also allows to copletely detach the pitchbend and modulation levers, for the pitchbend wheel even separatly for up and down (!) and map things freely in the modulation matrix, and this for pitchbend on demand even separatly for pitchbend up and pitchbend down! This gives you INCREDIBLE possibilities! So you e.g. could blend from lowpass to highpass by pitchbend up, widening spread by pitchbend down, etc. etc. It's only limited by your fantasy! This is very handy for basic controller keyboards which don't offer knobs but only the obligatory pitchbend and modulation wheels. Which with you now can do whatever you want. Only limited by your fantasy!

- Below the octave-switcher (note: voltage-based, so affects key-tracking if activated) there's now an additional button which lets you lower the base-pitch by two ocatves (you then still can switch individual octaves with the octave switches above) which can be wanted/needed/useful in some situations when the pitch tends to become high-ish (e.g. when using the arpeggiator with four octaves which always go upwards) and you can't get low enough with the octave switcher to achieve a comfortable pitch range.

- MIDI learn now allows to learn one source to several targets as often demanded

Arpeggiator:

The arpeggiator now offers a new "digital" display which dependent on the chosen preset now shows which knob is mapped to which function in the chosen preset (which changes). Furthermore pedal hold (quickly depress and again release the damper/sustain pedal within less than half a second - which can be used to activate and deactivate hold hands-free while playing, staring/stipping the 8-step sequencer in the "Record" preset) now is labeled as a function and can be switched off on demand (standard is on). Also now you also can use the pedal to fix a maual chord in the manual chord preset (inspired by the chord hold function of OB-X).

Matrix Modulation:

Finally - yes! oh yes! there's now an expandble fully-blown extremely sophisticated matrix modulation section (button to expand at the top of the LFO section, only covers the LFO section when opened, LED shows if it's active or not when closed) which offers not less than 5 matrix modulation slots (the upper two with polyphonic sources, the 3 lower ones monophonic sources) which let you freely assign modulation connections using many sources and targets per slot. This opens incredible possibilities!

The five slots are called Mx1 to Mx5 (Matrix 1 to Matrix 5). Each section offers a source and destination slot, and in the middle controls for the amount (Amt), divide the amount by 10 (0,1) and invert (+/-) which give you all control you need and this very quickly and intuitively. The 2 polyphonic source slots offer 14 sources and 17 destinations, and the 3 monophonic source slots offer 13 sources and 23 destinations.

To increase the possibilities the matrix-modulation section offers two additional envelopes (one polyphonic, one mono, optimized for modulation via quick controls) as well as two additional LFOs (one monophonic - fully blown including 4 different waveforms (WF), key trigger (KT), sync to song tempo (SN), and one polyphonic, so per-voice (so in fact 12 LFOs) as available in Matrix-12) offering key trigger and 4 waveforms. The matrix modulation section also offers buttons to detatch the pitchbend wheel (individually for up and down!) and the odulation wheel from their fixed mapped wiring - in order to freely map stuff in the matrix.

Now to the matrix itself: First on the individual slots also can modulate the amout of other slots - which gives you incledible flexibility! Like this you e.g. can map a polyphonic envelope to a source in one of the two polyphonic matrix slots, leave the amount at zero, and then map one of the 3 monophonic LFOs to the amount with one of the 3 monophonic source matrix slots. Like this you can send the monophonic LFO source to each voice individually and modulate the amount individually per voice, e.g. for a voice-individual LFO delay! Just as en example.

Furthermore all 5 slots also offer fixed value as source, which e.g. let you increase a parameter range if you're not pleased by its given limits. Also, the polyphonic slots - and we think this is probably sort of a world-premiere - also can use the trimpots of the voices as modulation source! If autotune is applied to one of the four autotune parameter groups (cutoff, portamento time, filter envelepe decay, filter envelope release) the dedicated trimots have no effect/are out of use and so free for a different puropose, So you could use these to idividualize ANY parameter in a voice separately for each voice-pair (1-77, 2-8, etc.)!

What all you do with this is only limited by your fantasy. Also, there are further unusual tragets like spread, panning modulation, filter mix or even filter type! Also to mention is that regarding pitchbend you can map pitchbend up and pitchbend down separatly to inidividual destinations! As you can crealy see now this new matrix modulation section offers you INCREDIBLE possibilities. If there's anything you can't do in the standard synth interface then you probably can do it here.

Note that the top-right "Global N" button must be switched on in order the set modulations have any effect. This has the big advantage that you anytime quickly can deactivate the whole modulation matrix preserving the settings which are still there in the background. The activity led too is mirrored on the outside of the section so that you also can see if the matrix is active when the section is closed. This is important, since adding virtual voltages to the parameters also will change their behhaviour.

It all works exactly the same as in a real analog synth. Applying madulation to a parameter won't change its control. It will apply virtual voltages in the background which you can see and which may change the behaviour or range of a dedicated button or knob. That's why a global quick matrix-deactivation button is really important. It lets you check the "original state" versus the altered state. Did we forget anything? Let's hope not. The modulation matrix gives you INCREDIBLE freedom and possibilities. There's virtually nothing that can't be done.

New Presets:

Finally, the synth includes 300 new awesome presets showing off some of the new features! The library also contains an extended Famous 80s A-Z section at the very bottom of the categories which offers no less than 475 alphabetically sorted famous 80s sounds including many new ones!

POSTSCRIPT:

As you could see, we tried to include and fullfill ALL of the user's demands and wishes we collected over the years - so: more logical interface, no hidden features, better preset management with favourites and categories, modulation effects, voice-reset on song start, improved sound quality, even more famous 80s presets, modulation matrix, in-synth switchable interface size, one source to several destinations midi learn
