Welcome aboard Jonboy...
First - you will LOVE your Quad-Capture...at least I can say I love mine...the VS Pre's are nice and clean...
and Autosense and the built in Compressors are a bonus..
As far as DAW....that's a personal choice...One thing I can tell you for sure...
Put your system specs in your Signature File...it will save a LOT of time
when seeking help here...
Sonar is a great DAW...that being said...they all have their strong and weak points...
my BEST advice....find one that WORKS FOR YOU! Demo them...they all have Demos..
Get the X2 Demo....try it...see if it "feels right"
Get the Cubase Demo...ditto
Get the Studio ONe Demo...ditto
Get the Reaper Demo....ditto
etc...etc...etc...
You get the idea...because, in the end, YOU have to be comfortable...not the people HERE...
