After working perfectly happily for a couple of days, Melda SuperLooper VST3 has begun crashing Cantabile. I haven’t knowingly updated anything between working fine and this constant crashing.
I’ve switched to the VST2 version of SuperLooper, which appears to be working fine for now.
VST3 plugins are hit and miss in Cantabile. There is a known issue with IKM’s Miroslav Philharmonik VST3 that has been documented here. The VST2 works great, so that’s what I use.
