I was at a gig last night with 2 bands, the guitarist from the first band used the same amp as the one from the second. I realized - if there were a way to read and load up your presets from USB without wiping the existing ones, and that your presets would disappear when you pulled your USB stick. I think it might require "Boot from USB" so that system wide settings like constant latency would be as you want them. (Btw, constant latency should be set per patch.) It might even mean that different operating systems could be accommodated (which might mean your ancient laptop you use on the road would work with Rig Manager).
Yes, there is a way to do this but it requires backing up the existing patches. Another guitarist using my KPA might end up wiping my setup, patches and performances without meaning to.
What I'm asking for is to power up the KPA with a USB stick and/or a laptop connected, see a dialog asking "Boot from USB / Computer?" Saying "yes" leaves the internal memory alone, but the internal setup wouldn't be available. The KPA would look just like mine, which I had left at home.
This would make the KPA even more appealing as a universal backline amp.
Thoughts?
