My luck with the native recorder has been variable. Not needing jack would simplify things a LOT. I do LIKE jack_capture but it's another link in a sometimes fragile chain. _______________________________________________ Rosegarden-user mailing list [email protected] - use the link below to unsubscribe https://lists.sourceforge.net/lists/listinfo/rosegarden-user
