well, they emulate a guitar amp through your computer
one of the proghrams did list a sound card as a requirement, that is why i started to think i needed an external one.
I actually got one to work, but with a second delay. So, i think i do need an external sound card and a decent one at that because i read some stuff and people with crappy sound cards experienced similar performance as i did with the sound built into the motherboard
if anyone has had any experience with playing electric guitar through the computer post up
