thanx! this entire patching system is wicked! im using qjackctl... you could never expect to route midi and audio events this way with standard win apps even with rewire... this is awesome... other thing is that i bought the sb audigy just for using it with the asio drivers, but with jack you dont need that right? would a standart cheapo soundcard work this way? with the same latency? (using the planet ccrma stuff ) im asking this because one friend of mine wants to buy a soundcard just to do the same thing, play with softsynths realtime (low latency) from the midi keyboard... maybe a sb live would do the job? thanx for the fast - straight-forward answer --- Chris Cannam <cannam@xxxxxxxxxxxxxxxxxxxxx> escribi?: > The generic answer to "how do I add effects to this > JACK app that > doesn't immediately appear to support them?" is to > use jack-rack, > which is a very nice standalone JACK effects rack, > hosting LADSPA > plugins.
