S-GEAR VST3 ProConvolver cabinet models fail to load in Presonus Studio One v3 on OSX 10.12 and later

This problem affects the S-GEAR VST3 plug-in running with Presonus Studio One v3 on MAC OSX 10.12 and 10.13.

 

On loading an S-GEAR preset, sometimes the cabinet may fail to load, leaving a blank where the cabinet model should be displayed.  Clicking the ProConvolver to select a cabinet model can lead to a crash.  

 

The problem is being investigated.  To avoid this problem it is recommended to use the S-GEAR AudioUnit with Presonus Studio One v3.
