While this is my first post, I am in no way a new user of DP (I've been using it since vers 1.4). (And still have the original manual and floppy discs to prove it!)
Over the years I have mainly used DP to compose music for theater and films (using mostly MIDI, and now VI plugins), and for doing sound effects for theater.
More and more I find myself using DP to do audio editing for video and radio production (something that I have always used Pro Tools for in the studios that I have worked in), and I am finding one very disturbing lack in DP's tools set; that being Pro Tools "Shuffle" mode, especially when doing edge edits.
To add a little extra info: In Pro Tools, if I select Shuffle mode and edit enable several tracks, I can then use the edge editor (the [ icon) to trim away the beginning of a soundbite and all of the other tracks as well (keeping them in sync). I can approximate this in DP by using the Snip command, but the problem comes in when I want to ADD some time to the begining of a soundbite (for timing purposes in a VO, etc). In Pro Tools I can just drag the edge edit back (to the left) and everything moves in sync. I have yet to find an easy way to do that in Digital Performer.
For those of you who have done VO on PT, I am sure you will understand what I am talking about. For those of you who haven't, please ask questions and I will try to clarify what I am looking for.
Don't get me wrong, I love DP for a lot of reasons, but this is the single thing that keeps me from ditching Pro Tools altogether. (and advising my client studios to do so.)
FWIW - I am still on DP 4.1.2 - if the more recent versions offer this, I've obviously missed it in the upgrade FAQ

Thanks for any help you can offer
