Digital DAWs are not mechanical unfortunately.
Transposing, pitch shifting and even frequency shifting are the options you have with digital.
What's called 'Varispeed' in a DAW (See Logic 9 they actually call it Varispeed, Reason, Reaper etc... to see how it works in a digital DAW context) works different than 'Varispeed' on a tape deck or turntable, you wouldn't use it for the function you require.
Transpose or pitch shift the mix so the player can track to it in tune, pitch shift/transpose the stem back again once you've captured the performance. The advantage you have over the old days is you can keep the tempo the same, analog varispeed would alter it in order to get the pitch shift.
Sonar would benefit from 'Varispeed' but not for the purpose you are citing, you've been given the best options for doing that already, they've been available for years, and in Sonar too.
Some people offered you several different solutions, you have acknowledged one of them and ignored the rest in your insistance of making a lame point.
It would certainly be cool to see it in Sonar but you can already get what you are talking about doing in Sonar already, as you will have learned if you had the courtesy to read the replies you got.
It works this way in every DAW context I've come across so far: This is how Sonar users can benefit from Varispeed.
Varispeed isn’t the sort of tool you’ll need to use every day, but it’s the sort of tool that you like to know is available to you. Every now and then you’re halfway through a project when you decide that the tempo just isn’t right and the song should be slower or faster. Varispeed allows you to determine which tempo suits the song better, quickly and easily.
Alternatively, you may be having trouble recording a difficult part in the song. While Varispeed may not be your first port of call, after struggling with the part for too long it’s convenient to be able to slow the whole project down, record your part, and snap it back to normal speed afterwards. Your new part will be in time with everything else.
If you feel like a cheater recording the part slower, at least you can practice at a slower tempo before working your way back up.
And, for maximum fun, Varispeed can be used as an effect as well.
I would agree the little slider on a tape deck or turntable, named 'Varispeed', was cool quick and responsive but it's not as simple in the digital domain due to the tie in with sample rates, so some transposition algo, has to emulate that idea, getting it working in real time is still the challenge.
Transposing/shifting a static sample of your mix and stem is still the simplest, most effective, way to go here, which is why zPlane Elastique got mentioned.
