Don't confuse them with realtime kernels. Lowlatency kernels are just configured differently, not patched. -- Want fast and easy access to all the code in your enterprise?

My recommendation, is to ignore the message, and try Rosegarden out with your existing configuration and see if you can notice any problems/delays. If there is a problem you can always switch kernels IF the version you are using is not necessary for the graphics driver you are using. -- Want fast and easy access to all the code in your enterprise?

Those kernel packages have usually "lowlatency" in their name. The message vanishes then. Lowlatency kernels are good both for Rosegarden and for JACK. -- ___ Rosegarden-user mailing list Rosegarden-user@lists.sourceforge.net - use the link below to unsubscribe https://lists.sourceforge.net/lists/listinfo/rosegarden-user

If you are using external MIDI synths, keyboards, filters, and other accessories, particularly legacy ones, they introduce their own errors which are bigger. Perhaps if you a sequencing an entire orchestra it might, perhaps, just maybe ;-) ram -- ___ Rosegarden-user mailing list Rosegarden-user@lists.sourceforge.net - use the link below to unsubscribe https://lists.sourceforge.net/lists/listinfo/rosegarden-user
