Something not working?

Windows blocked the installer

SmartScreen shows "Windows protected your PC" for new releases until enough people have installed them. Click More info, then Run anyway. The installer is signed by Calm Base Oy — you can check by right-clicking it, Properties, Digital Signatures.

My DAW cannot see the plugins

Most hosts only scan for new plugins at startup, so restart it first. If they are still missing, check the plugin paths in your host's preferences include the standard VST3 and CLAP folders. Some hosts keep a separate blocklist of plugins that failed a previous scan — worth clearing.

Is there a macOS version?

Not yet. It is planned, and there is no date. Windows only for now.

How many channels do I need?

An ambisonic field of order N needs (N+1)² channels: 4 for first order, 16 for third, 121 for tenth. VST3 stops at 7th order, so use the CLAP version above that. Your track must be wide enough or the upper channels are simply not there.

Something sounds wrong and I cannot tell what

That is what X-ray is for. Insert it after the plugin you suspect: it reports the frequency range over which the field's bands still agree on a direction, and the frequency where they stop. A field that has merely been rotated, mirrored or reshaped reads healthy — that is the point, those are not faults. Processing that pulls the orders apart from each other narrows the range, and X-ray names the frequency where it happens. Failing that, email with the plugin, your host, and what you expected.
