"Officially endorsed by Sequential"

Quoting the website :


For the first-ever official Prophet~5 plugin, Sequential has collaborated with GForce Software to honour the sound, feel and character of the original instrument in software. It brings together Sequential’s place in the history of analogue synthesis with our long-standing experience in creating expressive, authentic virtual instruments.

Across the Rev1, Rev2, and Rev3 character models, the Prophet~5 plugin delivers the tone, response, and musicality that made the original instrument so sought-after, from the warmth of the SSM designs to the punch and presence of the Curtis filter.

All of the original hardware functionality has been included, giving you access to the tones, behaviours and performance character that made the Prophet~5 a fixture on some of the greatest recordings of all time.

The original 38 factory presets from 1978 are included, alongside an extensive, professionally designed modern library of over 420 patches.

There's quite few Prophet-5 emulations already, I wonder how this one stacks up against others. Prophet-5 is one of my all-time favourite synths, and while I don't own one (yet! I'm sure one day), I've had access to real one many times, it sounds soo good. I really don't know how successful this plug-in will be unless it offers really more authenticity than current ones like U-he that has been out for many many years and is very good already. It will be difficult ...

 

Sounds pretty good in the video and I like the additional functionality.

Hopefully there will be a few review videos out in the coming days.

Thanks for posting.

 

No doubt G-Force will pull off a good emulation. Their Oberheim's are stellar.

 

Tested against Arturia, Softube and u-he, and it's definitely the weakest by quite a margin unfortunately. While I love GForce for having emulated so many Oberheim synths, I don't think their modeling techniques are great. All of them have a distinct flat sound that reminds me of not-so-great analog emulation that try to get their analog sound by simply slapping some distortion and high-end roll-off on the output. So not even speaking about authenticity, I don't think this sounds great. The u-he's filter section isn't really authentic, but the plugin itself sounds amazing and you still definitely get a very good Prophet sound.

When I compared the OB-Xs, it was the same story. I felt that the Synapse Audio one was the best in terms of sound (but I dislike the interface), followed closely by the Arturia and the Surge OB-Xf (free and open-source !). But the GForce had this distinct high-end muddiness that I don't hear in the hardware synth.

Who knows, maybe it's intentional and they want to add a sort-of tape workflow emulation. Regardless, it's not my cup of tea. To me, it sounds muddy and thin

Yeah on this you can hear exactly what I was talking about, especially on the brighter sounds like at 14:40 or 19:00.

 

I agree for the most part. I love GForce plugins, but in my quick initial testing wasn't that impressed. I mean, it doesn't sound bad, I just prefer others over it. My order would be Acustica Expanse, u-he, Arturia. I will give this more time and experimenting though for sure. I love the sound and workflow of the prophet, so the more the merrier. I own one, but still use the plugins regularly lol.

 

I completely believe you that the Acustica sounds great, but man fuck that company with their cringe CEO, stupid DRM and disgusting AI marketing.

 

Those are prices...!

It sounds perfect to me!

 

Time to compare it with u-he's Repro-5

At least Repro-5 also had Repro-1 though

 

Native Instruments Pro-53 is back and playable in an open-source Cmajor port in your browser - March 14, 2024

The long-discontinued Native Instruments Pro-53, a Prophet-5 emulation, is back and playable in an open-source Cmajor port in your browser.

There are countless audio plugins that you can buy or download for free. However, they don’t stay forever, and the time comes for a new version or the official discontinuation. Many plugins have already experienced the latter. The software graveyards are full of awesome code, including the Linplug synths (Spectral…), FXpansion Geist/Tremor, NI Absynth/Pro-53, and more.

Discontinuation does not have to be the end. A perfect example is the Surge Synthesizer, initially developed and marked by Vember Audio. Instead of discontinuing it, the developer decided in 2018 to make it open-source. The result is a massive community contribution over the last 6 years, raising the synth to new horizons. And a plugin that has been dead for a long time returns today.



Native Instruments Pro-53 Cmajor
No joke, the Pro-53, Native Instruments’ long-discontinued Sequential Prophet-5 emulation, is back thanks to the creators (Jules Storer, Cesare Ferrari) of the audio programming language Cmajor.

Side note: they founded Sound Stacks, which are part of Soundwide, the ex-supergroup of NI, iZotope, Plugin Alliance, and Brainworx. The new name of the Supergroup is Native Instruments. However, the creators also founded Cmajor Software Dev, independent of the NI group.

This is a relatively new C-family language designed specifically for writing DSP signal processing code. It has recently become open-source and is available under a dual GPLv3/Commercial licensing scheme.

Their website shows some examples of what is possible with Cmajor so far. One of them is a new port of the classic Native Instruments Pro-53 Synthesizer, initially released in 2002. They released it as an open-source web-audio application called Pro-54 that can be played from your browser.

Original Code
According to the developers, it’s based on a never-released internal C++ port of the original synth, including all the 500+ patches of the original plugin. The code is open-source, and they haven’t done any modernizing to it:

We haven’t attempted to do anything clever in terms of modularising the code into Cmajor graph/processors, and have left most of the original structure, even including a 1000-line main() function!

They also say the GUI was recreated in HTML/javascript using mostly salvaged low-res bitmaps for that authentically vintage feel.

The Audio Programmer YouTube channel had the developers in their videocast. Linked below. Interestingly, the chat asked if its possible to compile a VST, AU, or AUv3 (iOS) version of the Pro-54. The developers said yes.

I find the statement exciting. So it may be that we get the Pro-53 back in our DAWs, even an iOS after four years of its discontinuation. May 31, 2020, was the last day you could register the plugin. It is not clear from the information whether an agreement has been reached with Native Instruments here.

I’m excited to see how the project continues. Certain is that we can now play the Pro-53, eh Pro-54 in our browser again. And possibly soon as a plugin. It would be a great nostalgic news.

I dont think Gforce is that good, not that bad either, really, but What i dont understand is that they are in so good terms with oberheim and sequential as to be oficial partners! ?

 

Licensing fees and revenue sharing presumably.

*edit* clean up
