ccherrett,
I'm pleased you're making ground with this. Good to see another orchestral fellow join the community.
This is personal preference, but when you consider how many instrument/articulations you're going to be handling,
I opted for several maps, each with one bank. (My first violins run into two banks, so i have 1st violinsA, and 1st violinsB, each with one bank.)
This will make sense especially when you start using multiple ports in Rosegarden and Linuxsampler. Jack can handle as many ports as your hardware will, so you can afford to build a few, and not worry about having to condense things too much.
It's really quite easy to get into the swing of setting all this up, once you have some momentum, but it is a lot of work too, so i respectfully urge you to take your time and check what you're doing as you go. It's worth it for a trouble free setup.
When you've done everything, i also suggest you save the completed Rosegarden template as your default studio. This will ensure all that hard work you did setting up matching ports, in the midi devices window will stick across restarts.
So startup would go something like:
Jack
Linuxsampler backend
Fantasia, and wait till it's finished setting up your template
Rosegarden.
some notes on JackControl. (Qjackctl)
you can build a template in Jack that ensures your ports cable up correctly each time, and you do this from the jack patch window (patchbay.) When you make a new template it will ask you if you want to use existing connections. The answer is NO.
Each little icon you see in the patchbay window is called a socket, and you can have as many as you like.
I did a lot of experimenting with this, and ended up building a socket for each instrument, for both inputs and outputs.
1st violins LS output (socket 1, for example) with two audio output plugs, L and R.
And so on.
This saves a LOT of hassle handling large numbers of ports.
I strongly suggest you take your time here and label (and you can make aliases for both sockets and plugs) each socket and stereo pair of plugs, according to your setup with Linuxsampler, and whatever you're going to use for the audio. (Be aware rosegarden only handles 16 stereo pairs max.)
Good luck, and if you have more questions, please, ask. We're here to help as best we can.
Alex.
