Before you install.

I design and build these tools for audio/visual experimentation. They are regularly changed/updated, but to be honest, I haven't purchased code signing, nor do I plan to any time soon (there are various reasons for this, but the main one is that I have not 100% settled on the finished designs). That's why Windows may show you the typical jump scares about an unknown publisher.

Use the download channels on blkpine.dev only. The release checks verify cryptographic signatures and SHA-256 file hashes to confirm the release’s origin and integrity. These checks are separate from Windows publisher signing.
