I plan to record all of the instruments separately using this setup:

-Dell PC (Pentium 4, 1GB Dual DDR SDRAM at 400 MHZ, 160 GB Ultra ATA/100 7200RPM hard drive)

-SONAR 4 studio edition

-ECHO MIA soundcard

-Behringer TRUTH active monitors

>>I have a 10 input Yamaha mixer to run mics through. Is there anything else I need or any problems with the setup I am considering? I really appreciate the advice.
