#274 Playback Speed causes Crash

[N K]

Hi people.
I recently upgraded my macbookpro early 2009 into Catalina by a patcher provided somewhere else by a user dosdude1, for unsupported macs.
Now, everything is running perfect. I mean apps, software whatever.

Sonic Visualizer is also working with all plugins, except!!! the playback speed function.
Everytime I change the speed up or down, the software cashes and I get the following bug report, which I attach to this message.

I do not understand the report. Maybe someone can shade a bit light on this?
Thanks.
