Yeah but you were likely set up to play what you knew, in a studio setting.
We got trains passing by right outside, bands in other rooms bleeding through the walls and we got no idea what we playing before we start playing.
It just isn't worth setting up for top quality sound recording for what could essentially be a few hours of really bad improvised playing. If we ever decide that we will do a 'finished' song, the drummer will set up solo and we will spend 30-60 mins setting up just his sound so we have it all. We would even go as far, I would hazard a guess, at using the triggered sounds on Seperate channels for seperate EQ/Mixing.
It just isn't worth that level of commitment for what we are currently doing.
