[linux-audio-user] Way to suspend Jack clients

Hi everyone, I'm looking for a way to suspend Jack clients so that their DSP process() callbacks are temporarily bypassed and outputs replaced with silence. I'd like to do this from a server level. I see using various softsynths and apps together in a live situation. This is part of refining my toolkit of instruments that I use for looping and performance. What I'd like to do is suspend apps that I'm not currently using to keep CPU cycles down. For example, AMS alone eats 50% for those fabulous analog sounds in 4 voices. I'd like to be able to switch between AMS, Beatrix, Aeolus, Hexter, and other apps without all that loading, exiting, and reconnecting of ports. As far as I know there is currently no way to tell the Jack server to suspend clients. Short of patching each of my favorite apps to do the suspend, can anyone see a way?? Or perhaps Paul would consider adding this functionality to Jack. Thank You & Kind Regards, -Mercury
