I tried the demo when it came out. but for $100US I decided to pass. I have Softube transient designer, the melda multi-band transient, LVC-audios excellent Transector and iZotope's transient tool in their channelstrip.
But after the demo expired I found myself wishing I had BSP. the other transient tools I mentioned are all excellent and they each have their own characteristics and sound. I actually passed on the Plugin Alliance Elysia nvelope because I felt it didn't give me anything different than I already had.
But with BSP it has a very nice clear sound and a lot more control over transient design. it's, well, sweeter sounding to my ears. the other transient tools I have are still useful as they are unique sounding/acting. I was working on a track where I wanted to work with track transients but the other transient tools I mentioned just were not clean enough, and I wished I could have better control over the freq range of the processing.
I ended up buying BSP last night and using it on the track. it made a big difference. so at first I thought it was a bit redundant but now I am happy to have it in my toolbox. I think it could also be a creative tool with the A/B morphing although I haven't delved into this yet. for example, put it on a drum or sequencer track and morph the transients in sync with the tempo to give the track some interesting motion you don't normally hear.

NEW: I can not find a PDF manual for Bittersweet Pro. the only manual appears to be an HTLM manual linked to from within the plugin. so... here is the content of the HTML manual converted to a PDF manual. sorry about the mouse cursors on the graphs, I didn't see it there at the time when doing the screen shots. oh well. also a little plug on the last page
