Hi,
It seems that a plugin is causing the app to crash before it can load. As a temporary fix, you can delete the app's data to reset it.

I will add this issue to the next version's todo list, as there ought to be a mechanism to blacklist plugins which don't load properly on some devices.

Hi, was the problem resolved?

No. I uninstalled the app and reinstalled it. Version 4.02.
It crashes immediately.

Did you look at the stack trace? It mentions several Echo and Delay plugins.

Abort message: 'engine is NULL'
(delayline::delay_simple(float, float, int, int, int)+1356)
(Echo::out(float*, float*, unsigned int)+200)
(run_echolv2(void*, unsigned int)+784)

there ought to be a mechanism to blacklist plugins which don't load properly on some devices.

A better solution would be to track down the NULL pointer exception and fix it.
There may be a race condition in your initialization.

Knock knock
Race Condition!
Whose there?

You were right. There was indeed a race condition between the UI thread and the Audio thread. Fixed in 17df08a

I've published an update (version 4.03). Do check it out and see if the problem is fixed, so I can close the issue.

Thanks.
