This is a session management script I did for our band's gig. It worked pretty well, but I just thought maybe I should try to find something a little bit more modern? Mac users have Main Stage and stuff, and I'm just writing poor old BASH scripts. Luckily writing these is quite fun!

This script captures pids of all the processes it executes. That way I can kill every process individually. Nice! All the connections are made by QJackCtl Patchbay.

What do you think about this? And what session management I should try? Jack Session really didn't work because many programs lack support for it.

The only problem I really had with this was that at the last time Intro sequence didn't start. I think mplayer isn't the best option for playing raw wavs through Jack.
