Right.. Vegas Pro is, and always has been, the easiest, quickest, and most intuitive multi-track audio recording application (despite missing out on some fundamental audio update requirements in the latest version).
I use it for audio multitracking/mixing in preference to Acid, except when MIDI of soft-synths are required.
The last separate "Vegas (Pro)" video and audio was version 2.0. Some of us weren't very happy when Sonic Foundry combined them into one product but we got past it.
