@torerk you may want to disable the Nvidia HDMI audio in device manager it used to be an issue and may still be, it used to cause timing errors.
By default I disable HDMI audio and all HDMI audio devices.
Just a thought.
Cherry Audio is the only Quadra VST3 available around $39 that I am aware of.
Arturia do a good Prophet 5 now two versions but not cheep around $199.00 they do sound good though.
Revision 3 sounds better to these furry ears, so many have covered this in so many way it would be inappropriate to compare, mix works well here on my Events.
@Barth I can confirm that the VST 3 version of the Wavestation and the M1 do tno retain the patch saved in a project. I would report this to support@cakewalk.com
