Please help on my first midiguitar3 attempt

I get this when trying Midiguitar3 beta for the first time and don’t know what to do…please explain in simple terms…thanks

The MG3 beta is limited to one sample rate: 256. That limitation will be removed in the release version, but for now, you need to configure your audio interface for 256.

It’s 256 or lower.
In some DAWs you need to arm the track for this message to go away.

i think that message (441 unsupported/daw) may happen when using non asio drivers.

what is your os version and which audio interface are you using?
