Then just do it out of respect for TUS, who did all this hard work and gave it to you for free.

I don't have a dog in this fight, but you ask an interesting question that needs an answeremasters wrote: Fri Feb 06, 2026 8:12 pm I'm not an attorney, but seems to me it would be hard for Roland to prove harm with the JP-8000 emulator, if a case went to court. The product has been discontinued for decades, Roland receives no revenue from the JP-8000 at this point (they don't even have a JP-8000 software synth available) and if the reverse engineering work was "clean" in its approach - what grounds would harm be based on?
In this case Roland could claim easily claim harm because it would hurt their ability to make a profitable plugin based on their IP in the future. We simply don't know what roadmap they might or might not have with developing one.
Now maybe they will do it or maybe they won't and if they did maybe they could win or maybe they would lose. That's above my pay grade, but Roland absolutely could claim harm against future abilities to make revenue and they have a long and proven track record of doing so with other Synths

Even if they make an RCM version, to have a case, they'd have change the tos or remove the file.
Realistically, the chances of them doing any of those things, even after an RCM version is released, is slim and none. They aren't ogres.

Maybe but are you saying they could never claim harm which was the original question being asked?conundrum wrote: Sat Feb 07, 2026 6:20 pmEven if they make an RCM version, to have a case, they'd have change the tos or remove the file.

Emulators have already had their day in court with Nintendo. Nintendo lost. Emulators, no matter what they emulate, are here to stay. There is no legal action you can successfully take against emulation as far as I know.. only towards distribution of the ROM.. and in case the company itself distributes it, they can't do shit.IvyBirds wrote: Sat Feb 07, 2026 3:21 pmI don't have a dog in this fight, but you ask an interesting question that needs an answeremasters wrote: Fri Feb 06, 2026 8:12 pm I'm not an attorney, but seems to me it would be hard for Roland to prove harm with the JP-8000 emulator, if a case went to court.

This is 100% settled law. Multiple times over decades, from companies much larger and angry and more determined and with much more money on the line than Roland: Oracle, Sony, Microsoft, etc. They all lost. There's nothing left to discuss in any countries sharing the common copyright and patent treaties (which is most of them.)IvyBirds wrote: Sat Feb 07, 2026 3:21 pm I don't have a dog in this fight, but you ask an interesting question that needs an answer

Not only are emulators ethical and legal, the protection for them is even stronger: you can even use copyrighted works to help create the emulator, and without permission of the copyright owner.

It seems to be my provider. Switching off WiFi and using 5G seems to work. Could my provider be blocking dsp56300.com?

I am a moderator. I will clarify. Discussion about emulators is fine. Discussion about sourcing ROMs is not. This topic does not need locking. Any post that links to ROMs or how to obtain them should be reported.

On a related note, Retromulator 1.2 is in development. It will include a OPL3 code (Nuked-OPL3) and a Wurlitzer physical model core by Joshua Price, along with improvements to the Akai S1000 module. These enhancements will be built on the already included dsp56300 cores, which are free as always. For more information, visit https://www.discodsp.com/retromulator/
We donated $1,000 to the gearmulator/dsp56300 team as a token of our appreciation, but unfortunately, the donation was returned. While we don't fully comprehend the reasons behind this decision, we respect their choice. Regardless, our offer and appreciation remain steadfast.

@everyone
**Statement from "The Usual Suspects"**
Over the past days we have seen discussions in the community about the release of Retromulator by discoDSP, which is based on some of our open-source emulator projects.
Our project is released under the GNU GPLv3 license, which allows anyone to use, modify, and redistribute the code. This includes use in commercial products, as long as the terms of the license are respected. This is fundamental to open source, and we intentionally chose this license to allow experimentation and innovation.
At the same time, the emulator project was only made possible by years of effort from a dedicated group of volunteers, choosing to contribute their expertise so we could reach the state our project is in today. From the onset we all knew that this was going to be a passion project instead of a source of income. Our goal has always been to make our emulators available to the community in a transparent way, with a focus on authenticity, usability, and long-term preservation of digital synthesizers.
Each emulation we have released encompasses a full body of work, from core functionality, performance optimization, and an accessible UI unique to the feature set of each device. It is not enough to solve the purely technical challenge of emulation, they must be usable for both amateurs and professionals alike, at any level of production.
Following the community discussions around Retromulator, discoDSP made a donation of $1000 to the project. While we appreciate the gesture, we have decided to refund the donation.
We want to remain independent from situations where financial contributions could be perceived as influencing the direction of the project. Accepting a donation in this context could give the impression that some type of unique agreement or coordination with discoDSP has been made, which is not true, and not our intention.
"The Usual Suspects" remain independent, and our mission is unchanged.
Therefore, we believe that refunding the donation is the most transparent and fair approach.
We want to thank the community for the strong support, feedback, and contributions that help keep this project moving forward.

FWIW, using the real hardware as controllers is a great way to get the most out of these emulators. All the benefits of software with the immediacy and intuitiveness of hardware.
