Not surprisingly I still don't think the Melodyne and Arturia issues are related. I solved my Melodyne issue by freezing the audio. I tried freezing on the Analog 2 and that did not work. I think I stated on a different thread that sometimes Matrix 12V loses its patch memory and has a different patch than what I had originally. The recent Arturia update seems to have improved that issue, but it still happens sometimes. One thing that did not improve is an effect issue with Piano-V. I have a user patch, and very often, when I open Cubase (with a song I'm working on) there is no reverb, when there should be. Sometimes, when I switch patches and come back to my original patch it works again. Other times I have to turn off my computer, then turn it on again before it works right. Other times the reverb works, and there is an extra unwanted effect: a delay of about one second! This is really weird because I don't even think there is a delay effect in Piano-V, so I don't know what is going on there. I hope Arturia can fix this. I have had patch memory issues with Arturia for years with various Arturia products.
