Just a heads up. I just received an email from these people saying that their 25% off sale finishes in a few days. I must have shown an interest in their library at some point but don't know much about it. It could have great potential and the demos sound good.
I stress that I'm nothing to do with them. In fact I pride myself that I'm among a small minority of posters at Northern Sounds who isn't linked to a developer or to the music business!!
Rephrase seems very close to the Celemony Melodyne but at an affordable price. I don't know what Melodyne can do that Rephrase can't but I intend to find out. (I've just emailed the developer in the hope he might answer the questions). The demos certainly remind me of the Celemony capabilities. Celemony Melodyne is another of those software packages which I would have liked to use but is just too expensive for me to justify.
It does seem that this type of software (or approach) is a least part of the future. Look at synful, liquid sax etc.
