I don't really see the advantage of using a linux computer in your case.]
I did not expect anyone to see the advantage. I just ask you to accept this as something personal.
Since you already have a windows computer hooked to your DP, the philosophical objection to using windows doesn't seem to be relevant.
1. Currently, this is all theory; I have no Windows computer yet.
2. Even if I have to run Windows, I would still feel _much_ better if I can keep it separated, in a quarantine, in a cage. (Ie. no keyboard, no screen, no network connection; just running Ivory II, like a HW module would),
What DAW functionality does linux provide that windows does not?
1. I really don't want to connect a Windows computer to my home network, mainly for security reasons.
2. From Linux, besides the DAW functionality, I can access all the other Linux applications available on my home network. (web, email, listening to music, musical scores, music learning software, etc.)
3. Later I can run my (potential) home-brew DP-related applications (which I will develop on Linux, where I do all my development anyway)
Why use two computers when you can use just one?
Overall, I would like to limit my (and my kids) exposure to Windows to an absolute minimum, but I still plan to do a lot of fun stuff with the computer and the DP.
Hence the two computers.
But of course I don't want to run two computers.
My first choice would be to run a linux-native virtual piano, but Pianoteq can not convince me (yet), and the rest do not have Linux versions.
My second choice would be running the virtual piano in Wine, but with Ivory II, this is problematic, because of the iLok stuff, among other things.
My third chance would be running a virtualized windows computer (in VirtualBox, or something like that); if will try this, but I am afraid the performance won't be good.
I will only fall back to the "two separate computers" solutions if all other possibilities are exhausted.
But even in this case, the Linux computer will be a very-low consumption, disk-less, fan-less, totally silent thin client, connected to the already existing home server, taking up something like 200 x 200 x 50 mm, running on something like 30W, so that's really no such big deal.
