From the ALSA wiki
Here's a rundown of the stuff that's currently in use:
- x86 laptop running Debian, Fedora and a custom distribution
- Apple PowerBook running Mac OS X
- Intel PC running Debian, DeMuDi and Fedora
- Edirol UA-1x, SBLive! 5.1, laptop onboard controllers, M-Audio Uno MIDI
- A bunch of guitars ranging from an Oakridge steel bodied resonator to a Jackson PS4
The list of Linux distributions will most likely have changed by the time I click the 'Save' button.
I've got keyboards and stuff too, but I haven't done much with them yet. I'm also using a Behringer FCB1010 MIDI foot controller to trigger the recording and overdubbing of tracks (keeping my hands free to play guitar). More on the MIDI stuff another time.
As far as software goes, I spend most of my time with JACK and ecasound. I use the odd LADSPA plugin, Hydrogen for percussion, Audacity for the odd job and Lilypond for typesetting and MIDI output. I use Timidity++ and a few SoundFonts too. The Lilypond/Timidity++/SF2 thing is mainly for hearing ideas for instruments I can't play, such as piano.
Once my setup stabilises a little (I like to play), I'll try to write down more about how it all fits together.
