Hi, a few notes after some testing. I did a fresh start of Cubase, and opened a new 32 bit float 44.1k project. My Fireface 400 card had its buffer size set to 64 samples. Upon loading either Cypher, Amber or Strobe, I get the awful spike. When I entirely remove the plugin from the vst rack and load it again, the spike does NOT occur anymore. This scenario is the same for Cypher, Amber and Strobe. For Fusor, no spike occurs, probably because it's not a sound generating plug in itself. I repeated the procedure a few times, each time restarting Cubase and loading either Amber, Strobe or Cypher and it always responds the same: upon the first load I get the spike, then after removing the plugin and starting it again, the spike does not occur anymore.
I followed your lead and set the buffer size higher. This seems to get rid of the issue. Hope this helps in analysing the problem. My system config is in my signature.
btw, which IS the latest version of the beta? Because I am running the .28, I installed this one because it showed a later release date... should I go to the .29 even though this indicates an earlier release date? Is it the dates or the version numbers that are wrong?
