Yeah I still have the issue, I've grown kinda used to it, I'll just restart the DAW until it works. I do use ASIO, but I'm not sure what I could do differently with it, I have a Focusrite Scarlett 2i2 audio interface.
Thanks for letting me know. This is a known issue with Maize Sampler, but I have great news. GuyEngine is getting a huge upgrade. More user friendly, fewer bugs. New engine entirely. You'll still be able to use the old one but when it's out I would suggest swapping them from your projects.
