Frankly, I was hoping that by now this would be implemented in Vegas 4.x - after all, me and other people have been begging for this feature for aeons. I want to be able to reverse that audio snippet inside Vegas, without having to jump to Sound Forge to do it (creating oodles of unnecessary temporary files and a management nightmare).
Even stranger is the fact that Sonic Foundry never seems to comment on the issue.
Please respond and comment. Having waited for that feature since version 2.x I think I deserve a response.
Other than that (and maybe pitch envelopes, which I can luckily kludge with the Vibrato effect), Vegas is the most intuitive, handiest and fastest to use audio production tool I can imagine. It has made my life easier when working on tons and tons of PC game dialogue and sound effects.
