They could have at least paid some respect to The Usual Suspects by mentioning them, and their hard work within their release notes and on their site!!

 

I downloaded 'Retromulator 1.0' just to try it out to see if it was lighter on the CPU.
I installed it but it doesn't work on Intel Logic Monterey: no AU, no VST, no Standalone.
Nothing at all.

Logic show: Couldn't be opened

TESTING OPEN TIMES:
COLD:
FATAL ERROR: OpenAComponent: result: -1,0xFFFFFFFF
validation result: couldn’t be opened


So, either I've done something wrong or it's crap.
Just so I know: Is it working for you?

nope

lol they are crediting discoDSP as the ones bringing them back.

 

Maybe he just needs some paid tech support.

Why it is likely not working for you:
FATAL ERROR: OpenAComponent: result: -1,0xFFFFFFFF validation result: couldn’t be opened

On Monterey, the binary apparently doesn’t even get past the AU validation stage in Logic:

OpenAComponent: result: -1,0xFFFFFFFF
validation result: couldn’t be opened

This means Logic’s AudioUnit validation refuses the plugin outright.

Spoiler

Even though Monterey has the required C++ runtime, the AU binary:

Links incorrectly to old frameworks or JUCE modules that aren’t compatible with Monterey’s stricter plugin validation
Includes code patterns or DSP56300 remnants that Apple now rejects at AU load time.
Possibly flags in the plugin binary (build settings, Info.plist keys, or Mach-O slice issues) are invalid for Logic/Monterey.

So, it probably doesn’t matter what macOS you try on Intel. This particular Retromulator binary is broken at multiple levels: linker crash on 10.15, AU validation failure on 12+, because the build itself was never tested or corrected for these MacOS hosts.

Now why it won't work on Catalina:

the app is trying to use std::pmr::get_default_resource() from C++’s polymorphic memory resource library, and it’s not present in system libc++ (/usr/lib/libc++.1.dylib).

That symbol was added in Xcode 10 / macOS 10.15 SDK, but older apps built on 10.14 or earlier may link to it incorrectly or expect it to exist in a slightly different form. The app and plugins were built against a newer libc++ than what Catalina 10.15.7 actually provides, so it fails at launch.

Spoiler

1. DYLD Symbol Missing

Dyld Error Message:
Symbol not found: __ZNSt3__13pmr20get_default_resourceEv
Referenced from: /Applications/Retromulator.app/Contents/MacOS/Retromulator
Expected in: /usr/lib/libc++.1.dylib

This is the classic Catalina/older-macOS issue. A properly tested build would either:
Avoid std::pmr if targeting 10.15
Or ship with proper static linking / compatible frameworks.
Crashing immediately at load means no QA was done on 10.15
Crash on JUCE Message Thread

Crashed Thread: 0 JUCE v8.0.6: Message Thread Dispatch queue: com.apple.main-thread

The crash occurs before the app even initializes. A tested release would have caught this; developers typically test launch on all supported macOS versions.

Intel & Universal Binary mismatch

Mach-O universal binary with 2 architectures: [x86_64] [arm64]

The binary includes both architectures, but the crash only happens on Intel (x86_64). This often happens when a build is done for Apple Silicon first and the Intel slice wasn’t tested.

Behavior across multiple OS versions
Users report it failing on Monterey as well. If the dev had tested their “new” release, it would work on at least Catalina → Monterey. That it doesn’t strongly indicates minimal testing.

Summary:

The crash log shows a fundamental runtime mismatch, not a configuration issue on your Mac.
The dev hasn’t corrected it for the officially supported OSes.
Asking for paid tech support for launch failures is a red flag; tested software doesn’t behave like this.

 

Hi @Kate Middleton, you can do better than that! Make an effort and get over your defiant phase. Write proper sentences again; I know you can. And please start with a capital letter and end with a full stop. Your popularity is plummeting.

 

That about page is perfect for a company living only on past projects and developments. Nothing wrong with that, and produts are still supported.
Those are some real MVP developers but Arguru passed away in 2007 and Asnaghi went co-funding Renoise in 2008.
George YoHng I suppose only licensed some stuff back in the day.

 

You are an absolute weapon, mate. every single one of your takes is utter trash. it's either performative conflict averse nonsense, or literal LLM summary slop. i don't think you are actually capable of having a single thought that is your own and you come off as extremely disingenuous. jog on......

 

Legally yes, but I'm talking from more a moralistic standpoint.

 

I think when a company runs out of ideas or money, they'll see the true character of the people involved, because then they'll lie and cheat, sometimes obviously and sometimes cleverly hidden. They steal the ideas and data of others, not to save the world, but to line their own pockets. Only the rule of law and transparency can help against this.

 

While it feels unfair, how about importing sample packs without additional editing and then claim it "your" song.

I won't download discodsp because YOU are the usual suspect. You got my 100% support, because you came with the great idea.

 

? They do.

 

Nope too,bro.

Example: Everyone (Whatever IQ Species,Programmers etc) can be Wisdom Rich like Proffessors.And can Talk and do like a Book. But the School of Life is Different.Wisdom is not Wiseness.And it was Characterless to just take and giving that things a new Clothe. I mean ..Its not smart to put a "not your own Childs" in other Clothes without asking the Father...Its DiscoDidis fault
