Please be careful using them since they are beta. Eventually they might crash, generate loud noises and things like that. Also do not use them in real productions since parameters and settings might change until release and break compatibility.
To report issues just create a comment right to this post and please include detailed information about the issue, which plugin is actually affected and in which host and version.
The plugins are available to download until mid July in 32- and 64-bit, VST2 and VST3 formwats for Windows.
