Re: [Jack-Devel] Is JACK suitable for this?

In my bad and good experiences it depends on luck related to the mobo and audio device. If you should have good luck, all you need is a vanilla kernel booted with 'threadirqs' or a real-time patched kernel, https://mirrors.edge.kernel.org/pub/linux/kernel/projects/rt/ and what ever kernel you run, the rtirq script, https://github.com/rncbc/rtirq . If you should have bad luck with the hardware, you could try a lot of other things that might or might not improve audio latency and/or MIDI jitter. For me migrating from AMD based hardware, to Intel based hardware and avoiding the usage of a professional, but bad supported RME PCIe card by an USB class compliant prosumer device was the most successful step. "hundreds of audio channels", at least when using Ardour, are no big deal, even not with an energy-efficient CPU, with less horsepower. However, I wonder what you consider to be "lowlatency" and what else apart from the amount of audio channels might have impact on the load. Some people expect latency way lower, than any usual digital stomp box or 19" effect provides. YMMV!
