I tried to use Cubase LE once, but I didn't dig the workflow. As a hobby guitarist, I really didn't need all the features DAWs provide you with. At that time I used Digitech RP200 and other pedals and then switched to a computer setup using standalone applications such as Amplitube and Guitar Rig. But when I discovered Gig Performer, that immediately clicked with me, because I could connect plugins using virtual wires, no sends, etc. It was extremely easy to experiment with the sound, play along backing tracks, and record what I played (just to see where my mistakes are). I don't even need to use a MIDI controller, simply program markers and actions in the Timeline and sounds automatically change as I play (clean, distorted, lead, ...). I like it because it is idiot-proof.
