[BUG] Crash on loading "Lush" preset

[OwenMagelssen]

When loading the "Lush" preset, the application hangs indefinitely.

AU plugin v1.3.0 being run within Logic Pro X 10.6.3 on macOS Catalina.

Thanks for reporting the issue! Unfortunately, I haven't been able to re-create the issue locally (I don't have Logic Pro, but I can test in GarageBand which has a mostly equivalent AU implementation). I have a few questions which will hopefully give some more clues as to what is going on here.

Are you loading the preset from the preset menu in the plugin, or the preset menu in the AudioUnit window "around" the plugin?

Does this issue only happen with the "Lush" preset, or does it happen with other presets too?

Does the hang happen every time you try to load the "Lush" preset, or only sometimes?

I was loading presets via the menu within the plugin's interface, not the AudioUnit window.
The crashes have only happened with the lush preset, although the presets in general seem to load somewhat slowly.
After trying several more times, I was able to load the "Lush" preset once without crashing. It loaded for an extended period. That was the only successful load of the preset out of about 10 attempts.

Okay great, that's good to know! The only thing that really makes "Lush" different from the other presets is that it has more delay nodes, so I wonder if the issue is that the plugin using too much memory when it gets to that many delay nodes, and either the system or the host forces the plugin to stop.

One way test this would be to try running the plugin in "Standalone" mode, and seeing if the same issue occurs (you could even run the Mac "Activity Monitor" simultaneously to keep track of the memory usage). Another useful test would be to try adding a ton of nodes to ChowMatrix and seeing if/when the plugin crashes in the same way.
