Soundtoys, Softube, Plugin Alliance debuging error


#1

Hello,
I created some plugin that is analyser. And when I debug it in Logic Pro X or in JUCE plugin host example, everything works great until I launch any plugin from Soundtoys, Softube or Plugin Alliance. System just doesn’t allow me to launche those plugins when I am in debug mode. I wonder why.

I also tried new app, anunced on that forum: Pluginval

And found out that plugins from SoundToys just don’t pass tests. There are some info in log console, but I don’t understand it at all. But what is more strange my plugins pass all tests. It’s strange because I am still beginner so I doubt I am better programmer than people from SoundToys :slight_smile:

Does anyone know what’s going on? Forgot to mention that with other plugins I don’t get that issue. For example UAD, Fabfilter or Waves, work with no problem in debug mode


#2

It’s a fairly common (and irritating) technique that plugins use to terminate if a debugger is attached. It’s to do with protection and cracking but I’m not sure how effective it is.

For the plugins that don’t validate with pluginval, can you post the logs here? It could be worth pointing the devs at them. That was the whole point of creating pluginval :wink:

It’s not necessarily about being a better programmer than SoundToys, just that there plugins are probably more complex. pluginval tried to stress test and find all the edge cases in plugins so developers can automate some fairly rigorous testing.

Or if pluginval was running in debug mode, maybe it was failing intentionally for the same reason…


#4

Or if pluginval was running in debug mode, maybe it was failing intentionally for the same reason…

No, it was released version of Pluginval, and running independent of any debuger.


#5

So what did the pluginval log say? It should at least tell you what test crashed…


#6

OK, sorry for that. But now I’ve just tried again, and now all tests are passed successful. But even though there is still some warning window error:

And when it appears the testing is paused. And that warning appears always two times during one test. When you click OK it starts running further.


#7

What plugin is being tested when this happens? And what test is being run?

At a guess I’d say this is an plugin-internal UI error message. It could possibly be related to the quick show/hide nature of the plugin test. You’d have to ask the plugin developers for specifics though.

One final thing to check, what strictness level are testing at? (5 is a good starting point for host compatibility).


#8

What plugin is being tested when this happens?

Little Microshift and Little Alterboy.

And what test is being run?

Actually I don’t know. I think it was some default tests, because I haven’t changed anything, just clicked “Test selected”

For Little AlterBoy first warning happens when on console is: “Starting test: pluginval / Editor…”
And second just moment later when there is: “Time taken to open editor (cold): 2 secs”

And now (in opposit what I said earlier that there are no problems anymore) there are some problems. Log from console looks like that (it’s still for Little Alterboy):

Well to me it looks like it’s LittleAlterBoy crashing in this function of their own code whilst running the Audio Processing test with Testing with sample rate [48000] and block size [512].

I’d have to look at all the threads stack traces to be sure but it looks like a bug in their code to me. Seems like a timer callback is calling in to their LittleAlterBoyAUFactory which is calling a nullptr (line 4).


#10

Amen to that! One plugin from Air Music Tech just straight up crashes the host when debugger is running :angry: I suppose they have the luxury of “developing only” on their machines and not also writing music.
