Ardour live mixing: Backup solution?
ever since I first used a digital live mixing console, I've thought about using my pc and Ardour for live mixing. I'm talking about small to medium sized rock/metal concerts with about 16 tracks. I've got all the necessary hardware (RME HDSP 9652 with a Focusrite Saffire Pro 40 8in/8out + PreSonus Digimax D8 8in) and think that especially a version of Ardour I am not allowed to talk about here right now fits the live mixing situation (PFLs, Sends-on-faders...) perfectly.
My problem: Ardour is software, so I cannot rely 100% on it. It may crash at sometime. Do you have any ideas how to keep the signals on the PA/monitors on stage even in the case that Ardour crashes?
So far, I thought about using my HDSPMixer, setting it up to recreate the volumes that I've configured in Ardour. In the case of an Ardour crash, I could immediately load a preset in the HDSPMixer and at least have the signals without EQs etc. on the PA. In this way, I would have a very small time without sound. Then I'd have time to start Ardour again. I'd be even JACK-independent, only the Linux kernel mustn't quit on me ;)
Does anyone know a smart way to copy volumes from Ardour to the HDSPMixer?
Is there a professional way of doing this? I know that some really big bands use DAWs for live mixing, too.
