OTT vst plugin causes extreme cpu usage

[atvrider]

Adjusting depth setting when any audio is playing on the OTT vst plugin from XferRecords ( https://xferrecords.com/freeware ) causes cpu and memory usage to go so high as to lock up the entire system.

I experienced this problem using the MDA JX10 LV2 instrument with valhalla supermassive and the above mentioned OTT. The GUI of OTT also does not display.

LMMS version 1.3.0-alpha.1.102+g89fc6c9 Linux/x86_64
Debian 10

Now that it's 2024, let me recommend LOMM over OTT.

This is a general problem with automating VSTs as described in #8066. This problem will be fixed by #8253.
