I confirm with The Legend v1.10 x64 on Windows 10 x64, with several VST Hosts (Bloxpander, Live Professor, Gig Performance, Cantabile). It's a real problem to use it on stage...
A turnaround on Bloxpander as been to use the 32 bits version with jbridge, strangely the x64 host has no problem opening it, but it takes more resources than the x64.
