laptop with tons of vsti and reason with cubase sl using a echo indigo soundcard and sound forge with wave gold for mastering and acid to burn the cd. cd stomper to create my jewel case insert (my wife actually make the inserts). olympus d340r digital camera to take pictures for the inserts.
I use a behringer ADA8000 and an EMU 1212M. I run 4 of my 8 outs on the MPC to 4 of the inputs on the ADA8000 and 4 of my 8 outs on the ASR to the other 4 inputs on the ADA8000 and the ADAT opticals run from my ADA8000 to my 1212M for 8 mono tracks of audio and then my "sub outs" on my Behringer UB2222 run to the audio inputs of the 1212M for 2 more tracks of audio for my sound modules or electric guitar or whatever (I pan one left and one right for 2 mono tracks). This setup allows me to track 10 mono tracks at a time into Nuendo 2.0. Also depending on the song if I'm only using 1 or 2 tracks from the ASR then I'll just use the remaining inputs for the MPC and vice versa. It seems to work for me.
I take it by tracking, we are talking about either putting a song/beat into final 2-track form on some sort of physical medium (cd, tape, whatever) OR recording a song into some sort of multi-track device, digital or otherwise.
In any case I use digital performer. It is a sweet package, highly recommended.
