My idea for this project came from a few notions:
I wanted to be able to take a DJ performance to the next level...
I wanted to make real what I thought a solo instrumentalists performance should look like,
instead of what is actually brought to the stage by most artists: a two turntable performance
composed of nothing but prerecorded studio mixdowns.
I wanted to perform what happens in the studio - from session takes to the mixdown.
I want to show what "turntables + electronics" actually means to me.
How I made it happen:
I first compiled scores of breakbeats all synced to 95 bpm
(Hip-Hop tempo and courtesy mostly of Ubiquity Records),
then I chose about 10 of these 8 bar loops and imported them into 10 buffers in MAX/MSP.
I created four drum tracks which can all be playing at the same time, and each of those
drum tracks can have any of the 10 loops as its output.
These beats are the foundation of the song.  Each one of those tracks can be muted/unmuted and thrown
through effects at any given time, by way of MIDI foot controller,the device that I built
called the infini-tweak(www-ccrma.stanford.edu/~bzimring/Controllers/index.html), or through automation.  At the same time the paticular drum loop
running through that track can be changed at any time desired.
Then the idea was to play along with this beat while recording and create a live
studio session on the fly.
First the bass line is recorded into a buffer, then the guitar, and then the MIDI notes for they keyboard.  
Once the part is recorded it then begins looping.
Each one of these loops is also controllable in the same exact way as the drum loops.
Once these foundations are laid the idea is to mix and match the parts while
doing keyboard, turntable, and guitar solos.
To have absolute control of this project I built the system from the ground up using Max/MSP
