Working...

 

Need a good software engineer to help.

 

I don't fancy your chances, but I applaud your ambition...

 

The challenge is not in the hardware but in the software.

 

Well yes but I'm pretty sure there will likely be some nice hardware encryption keys or something in the hardware too so they can restrict the plugin to a specific interface.

 

Well, there are a lot of Eurorack modules that run on Pi, but the DSP in UAD might be a hard target. I'm not even sure if you could somehow meld a custom DSP chip to a RPi, don't think GPIO would be good/fast enough for that.

But an interesting idea nevertheless.

 

Still a software thing.

 

I think UA has developed a complete set of interfaces (signal processing, data structure, mathematical functions) for UAD and integrated it into the UAD-2 on-chip system.
The real difficulty lies in-you have to decrypt the DSP chip and copy all, and the result is: you will get the reason for the reputation of UA in the field of hardware modeling.
Then, you can continue to reverse their native shell - Start a company and compete with UA.

Maybe the truth is not so complicated. I noticed that the size of the native shells are not smaller than the best ITB plugins encrypted by iLok. Maybe the DSP only performs basic signal processing.

Who knows the truth?
Eventide, Sonnox, Brainworx, Softube know.

 

Only once you have the private key so you can use it yourself does it become a software thing.

For example look at the Nintendo Switch hack - you have to actually join two hardware jumpers in order to get the console into a mode where a jailbreak can be undertaken. That's not just software and that's just one example.

why not just emulate real analog warmth vibe then

 

Back in the late 90s the company I worked for had to partner with MPEG2 card vendors to do video playback. But folks in our research division (it was a big company) were making progress with software decoding of MPEG2. Back then Intel was promoting it's Native Signal Processing, an effort to do all sorts of DSP functions without DSP chips as their processors got faster and better at it with new DSP oriented instructions sets. Look where we are today. We have zillions of very powerful audio effects all done in software on today's CPUs. The Pi can't compete with these CPUs nor with a dedicated DSP's processing throughput. Then there's the whole software piece... To replace UAD hardware, the Pi would merely be a controller managing a dedicated DSP-based audio processor board. What would you gain?

 

whut? take a good look here, enlarge the pic: https://musiquedepot.ca/universal-audio-uad-2-octo-core-pcie-dsp-accelerator.html [/IMG}

its a sharc adsp 21469 kbcz-4 ! lets look at https://www.analog.com/media/en/technical-documentation/data-sheets/ADSP-21467_21469.pdf

nothing custom, just a plain old dsp! lets go on: https://www.mouser.de/Semiconductor...-DSP-DSC/_/N-86p5d?Keyword=ADSP-21469&FS=True why o why should anybody emulate that dsp, youll get 10 pieces for eur 250...

but... in the middle of the uad board theres a spartan-6 thats an fpga, an at-the-customer programmable device. glue logic, ram, rom, various cpus, everything is possible on that chip! the protection would be imho implemented in that thing, but you cant read out the programming of a fpga.

im not into raspberries, but arent they small slow cheap industrial control system-on-a-chip? i cant imagine that they got enough mips to emulate anything, besides 7 mhz amiga computers! but thats just an uneducated guess of mine

 

youre some bit faster and more educated

 

I'm sat here wondering if the people who voted false actually mis-read the question

 

You will need a DSP engineer who understand machine code and pipeline programming

 

and a well equipped hardware lab with high speed and zillion channels logic analyzers and a guy with lots of spare time who knows how to operate that not-so-cheap equipment... maybe buying an uad is the cheaper and faster solution if the op is so after the uad plugins...

btw, a c64 is rather slow, the die-hards program that thing while observing the bus lines with (slow & cheap) logic analyzers. maybe those got the spare time?

 

I'd like to see someone use a c64 for this: https://en.wikipedia.org/wiki/Commodore_64

 

How?

 

the idea isnt so strange, please take a look here: https://www.nilsschneider.de/wp/2011/01/24/dsp-56300-emulation/#more-203

sorry its in german, youll have to translate it. he had tried to emulate the powercore, but the project is stalled.

 

One more pointless thread.
