All 5 of the production machines have the following subsystem:
Arch Linux system custom 2.6.31,6-rt19 kernel with RT preemption (essential for Xrun avoidance - click and pops) Desktop consisting of openbox, Adeskbar and pypanel. Display manager is Slim
jack2-svn (contains netone; which is netjack1 within jack2)
Rtirq (RT pci priorities for sound cards; also essential for Xrun avoidance)
LinAS is the audio master machine. It hosts 4 Hoontech C-Ports (ice1712-based chipset) in an Alsa multi-array providing 40 channels of audio to the other machines via 'netone'. jack is running with 2 periods @ 48kH and 64 frames giving a 'round-trip' latency (in and out) of 2.66 ms . Can be run @ 32 frames (half the latency) but the samplers struggle at this low a frame rate.
Uses Gjacktransport to control the jack transport here and therefore the netone slaves via jack transport.
The Digital Audio Workstation hosts 'Ardour' as the main DAW software and also Mhwaveedit and Audacity for audio editing, Qjadeo for synchronous video playback with Ardour, K3b & GDC Master for CD mastering.
The midi sequencer machine. Runs MusE 1.01-svn and Linuxsampler with the Fantasia (java) frontend. Magic. Mscore is the Linux music scoring program, started by the creator of MusE, Werner Schweer.
Uses the program fst (free software studio) by Torben Hohn to run vsti's (virtual studio technology instruments) under wine. The two I run are Kontakt 2 and Sampletank 2. Both work 100 percent maybe better than under Wine.
This is the 'Video Server" This one specialises in distributing video throughout the complex via webcams using 'Cheese' to mount them. Kdenlive and capture cards are used to take interviews of Composers and Performers for web-based content enhancement. Qjadeo is used to playback vision also piped throughout.
Essentially hosts the Jc_Gui front end for Fons Adriaensen's Jconvolver. Using open source Impulse Responses. Gives reverbs to the mixing desk.
