Re: [LAD] Multiple JACK servers connected in one host?

the "engines" i'm referring to are your many multiple clients (19 or so). OK, I think I see what you are referring to: the switching nature of the client list, where the JACK server has to switch between. And this is entirely why it helps to run multiple JACK servers on multiple

Re: [LAD] Multiple JACK servers connected in one host?

although it isn't proven yet .. i think that your problem may come from the fact that you want to have 19 different engines, and you keep flicking switches to go from one to the other. Nope, I don't want to switch engines. Everything runs at once, and runs very well by the
