Virsyn Tera Pro 2.1, new free updateadds the option to unlock RingZ via an iAP, a Mutable Instruments Ring-based resonator engine.
Tera Pro is one of the most powerful synthesizers on iOS. It’s fully modular but does not require patch cables. A great bonus: users of Apple Silicon Macs can also use the AUv3 plugin version in Ableton Live, Reaper… without paying twice.
Harry Gohs, the developer, has made the synth app more and more powerful over the last few years. For some time now, he added the ability to expand the engine via iAP. You can unlock wavetables, 6OP FM synthesis or supercharge it with the Mutable Instruments Plaits macro oscillator algorithms. In the new update 2.1, another engine that can be unlocked.
Virsyn Tera Pro 2.1
As you can read in the title, this is the RingZ engine. This is based on the popular open-source Mutable Instruments Rings module. Once purchased in the app (iAP), you add a resonator engine that you can use flexibly. It brings physical modeling synthesis to Tera Pro.
Just like the original Eurorack module, the RinZ engine has three modes: modal synthesis, sympathetic and string resonators. It also features the same parameters for shaping your sounds: frequency, structure, brightness, damping…
And all the parametres are fully modulable with LFOs, envelopes, and more. Very interesting is using the multi-segment envelopes, allowing you to create very complex, organic-sounding sounds.
First Impression
A nice upgrade for the Tera Pro Synthesizer. The app has plenty of synthesis options. Physical modeling was still missing here and the RingZ iAP now does this job.
Virsyn Tera Pro 2.1 is a free update for existing users. The new RingZ upgrade is available for $9,99 via an in-app purchase. Tera Pro is on sale for $6,99 instead of $14,99. It runs as a standalone app and AUv3 plugin on iOS and macOS (Apple Silicon computers only).

I have some heartburn about these new IAP modules. The developer has taken the open source Plaits and Rings code that the brilliant Émilie Gille provided as a free gift to the music community and wrapped it up in IAPs. I see no indication that the developer is giving anything back to the open source community in return. Looks like a profit grab that is freeloading on the work of others.
true, don’t know if this “free” to the community applies only to module clones or also part of entirely new products. Tera Pro is an own app but has the algorithm, like many hardware synths (MicroFreak, MiniFreak, Anyma Phi…) They are also not free
I understand your point and I agree that there are definitely some grey areas on this topic. I personally think there is a distinction between incorporating the code inside a larger hardware product vs taking the Mutable Instruments code, putting a few software hooks around it, and selling it as a $10US IAP. If you buy a MicroFreak, the MI code is not a feature or an add-on that you pay a specific price for. Korg’s mis-steps regarding it’s use of MI code has been well chronicled, including this article that includes Émilie’s side of the story (https://sonicstate.com/news/2019/01/26/namm-2019-mutable-instruments-responds-to-arturia-microfreak/). Do the VirSyn IAP’s credit Émilie in the app or in it’s documentation?
One of Émilie’s requests with regard to the use of her code is that the original Mutable Instruments product names not be used in association with the code. Most hardware clones and the modules in VCV rack and the recent Disting EX algorithms (both which are free) use different names (and give full credit to Émilie). VirSyn honored this request with the Plaits IAP, but not with the new Rings IAP. It is interesting that the name VirSyn chose for its Plaits IAP is “BrainZ”, which is the name that Behringer uses for it’s Eurorack module with Plaits code.
BrainZ is not a protected name, so he can use it 😉
I’ve ported Émilie’s code to Prologue/logue SDK and provide the plugins for free to community. hopefully the new NTS is a platform for a Prologue II. the smattering of extra memory and CPU will allow more of Émilie’s code to reside in user oscillators/effects in a future product. also free! i’ve never been a big open source guy, but when in rome!

“I have some heartburn…”
“I see no indication that the developer is giving anything back to the open source community…”
I could throw out my guts if I’m reading such a bullshi…
You are such a hypocrite…pretending to be a good, taking care of others, but just talking and blahblah…the hole discussion is years old and even you by yourself posted here the answer Emille gave to the community years ago.
Ask Tom here from synthanatomy (and 60 million other wp-users) how much he is giving back to the open-source-community or to automatic because he’s using wordpress.
This has been disussed a thousand times, so why do you come up with this subject here again? Just to post something…?
