Hi I'm a complete noob and want to record track by track (me alone) and so some sequencing/looping. I plan to build the following setup: 1. A linux machine with rt kernel 2. ECHO Audiofire 4 (yet to buy) 3. mic to define (sm 58?, some diy with WM-61A?) to record voice and conga/kalimba/bongo (yet to buy) 4. Line in from Rockman + Guitar 5. Line in from Theremin 6. some looping software like sooperlooper controled by midi footswitch 7. Ardour 8. Seq24 sequencer, hydrogen drum machine 9. Audiotechnica ATHM20 headphones for monitor (yet to buy) 10. yet-to-choose near field monitors... advice? (yet to buy) Selection of interface is mostly because it's "supported" by some open project. Does anyone have experience with studio around linux? What about the ECHO Audiofire 4? As you see budget is as low as possible, I'd say 1000 to start with a basic setup .
