By popular demand, bug reports and feature requests for VCV Rack are now allowed in the VCV Rack category #rack. However, this is a user group, so VCV developers will only read and respond to issues posted on GitHub.
See https://vcvrack.com/contact.html and https://vcvrack.com/manual/FAQ.html#i-found-a-bug for instructions for sending issues directly to VCV.
As always, you may email contact@vcvrack.com for issues with VCV Library purchases and VCV-branded plugins.
