Temecula DSP added Dual Engine. I guess that makes it half a Quadraverb now.

Also, ArtV released TurboAlexis, which is just one engine but adds full editing of patches:

This looks cool, I've never used a MIDIverb but I'm always interested in trying out some unique sounds.

Gonna be brutally honest about TurboAlexis: publicly throwing out accusations at other developers based on suspicions you have, only to then mention that you'll be releasing a similar plugin around the same time, makes me wary. You could very well be right, I have no idea, but either way it's not a good look.
I'm not trying to fight or anything, just giving some outside impressions.

The Bloom patches are what made the MIDIverb II special. Worth having for those, pretty worthless otherwise.

On the webpage, it has a quote about the reverse reverb being used quite a bit by My Bloody Valentine, so I'm interested in hearing what that sounds like. Maybe it's nothing special, but it'll be interesting at least to hear if it sounds distinct.

Yes, they used the Bloom patches. You’ll instantly hear it.

This is a real nice unit that works and sounds incredibly well. I had the hardware unit years ago and it’s great to hear these sounds again. They really nailed it. Hard to believe it’s free.

ArtV credits the GPL project that did the reverse engineering and most of the code. The description clearly says TurboAlexis basically puts a pretty GUI on the core code. This Temecula one has very unclear provenance and does seem beyond coincidence it’s turned up, constructed with the help of gen AI also after the release of an emulation with published source code.

Let me explain where I'm coming from. The TL;DR is that they aren't just suspicions.

I have been working with the available OSS emulators for some weeks, so I happen to know the codebase and its quirks.

Thement's project is the only one emulating the MV2. It emulates all 3 devices, but in the plugin it wrongly sets all three devices at 24KHz, which is wrong for the MV2. See the sources for EFFECT_SAMPLE_RATE here. If this variable is changed from 24000 to 32000 the Midiverb II works at its correct sample rate.

The first time I got aware of this project I was on bed going to sleep reading the TUS Discord. I did read the materials on the web and they were claiming the sample rate of the Midiverb II being 24KHz multiple times and had a description of how the input filters were emulated matching the MV1 (but wrong). Exactly the mistakes I had seen in thement's plugin (it also uses the MV1 filters for the MV2). The samplerate is a thing you don't get wrong by accident if you have the device open with probes.

I was in bed and I couldn't check what the actual plugin was doing (just use the plain time-delay programs and measure if the times are in the ballpark), but I wrote on Discord that I was very suspicious.

When I woke up next morning, the site text with the 24K sample rate had been corrected (I'm EU time, he's US), the Internet Archive didn't have the page archived, but while the wrong sample rate and input filter description was gone, there still was a remnant of the wrong sample rate in the footer. See screenshot.

So we entered private message contact and TemeculaDSP claimed the AI writing the text (him not reviewing) and that it had been corrected. There it's acknowledged the usage of the E.Brombaugh videos and MIT-licensed EMU (90% of the work emulating the MV2). At this point I envision no Midiverb II open with probe points in a LAB. Then it's stated that the LFO programs were made by him with Claude (thement's project adds the LFOs but is GPL, not MIT; it disallows closed source usage). See screenshot.

At this point in time, while still very suspect I promised to keep it quiet as I never verified that the plugin was running at 24kHz on the first hours before the release (my text quoted on the other message, can provide screenshot too). That was until I found this.

It is a self-recognized fact that at least he's using the E.Brombaugh EMU code, which is MIT and does most of the legwork, so this quote alone points to a total lack of moral compass. This is only sticking to facts, no suspicions.

Additionally, the MV2 emulation of thement isn't emulating the triggered flange programs, which have an envelope follower circuit and I think also use the microcontroller and guess what? This project, while claiming to have reversed the LFOs independently stops exactly there too. This is a suspicion, not a fact, but it looks like a duck, swims like a duck and quacks like a duck.

So my position here is not to sit on this info for myself, as we OSS developers as a collective hate people marketing and profiting from what we offer for free. Everyone is free to its own opionion. This one is mine.

That is not exactly the case. Adding the UI having TurboPaco available was basically two/three Claude prompts and only around 2% of the work that went into TurboAlexis.

Among other things, TurboAlexis also modifies the emulator/disassembler to allow variable algorithm sizes with various interpolation algorithms and reverb modulation. This isn't a feature present on the actual device (or the emulator). While not being a humongous endeavor, it's some work.

DiscoDSP and TemeculaDSP really shat the bed this year, didn't they?

I considered to buy some things off these fellas, now I will not. Promptly blacklisted for shenanigans. It's easy for me. And my wallet loves it. Legit programmers' wallets love it even more! I already have a couple of others on my mind, who have delivered top quality non-AI code for years and really invested time and effort, blood, sweat and tears, into mastering their craft. I rather pay these guys. Why on Earth shall I not?

Then again, this is not really surprising. There was a fair warning of AI screwing legit people doing legit things. Legit programmers, artists, musicians, you name it.

From now on, every time I see AI involved, I will turn my back on it and go pay a human artist working hard for his money. And that's how it should be in all aspects of life. People will get so fed up with this postiche and artifice, they will begin to resist it. Because we will need some honesty back into our lives and this demand will only increase.

The more sparse genuine things will get, the more they will be missed. It's always been like that.

Disco and Temecula absolutely nailed it this year, didn’t they? Like, Olympic-level bed-making. Hospital corners. Five-star linens. Truly inspirational stuff.

I was not considering buying anything from these legends, but now? I’m thinking I should probably buy two of everything just to keep up. Promptly whitelisted for excellence. It’s hard for me. And my wallet is filing a formal complaint.

Illegit programmers’ wallets are thriving, honestly. Meanwhile, those poor “seasoned craftsmen” who spent years honing their skills—what were they even doing? Practicing? Learning? Putting in effort? Couldn’t be me. I’d much rather throw money at chaotic brilliance and vibes.

And AI ruining things? Please. If anything, it’s improving my life by giving me more questionable content faster than ever before. Efficiency!

From now on, every time I see AI involved, I will run toward it like it’s a flash sale. Human-made? Sounds slow. Sounds expensive. Sounds like someone tried too hard.

People getting fed up with artificial stuff? Doubt it. If anything, we’re just getting started. Give me more postiche, more artifice, more “wait, a human didn’t make this?” energy.

Because honestly, the rarer genuine things get, the easier they are to ignore. It’s always been like that… right?
