How To Use Varispeed In Logic

Problems with Varispeed in Logic X?

Hello,

Is this a known bug in Logic X:

I am trying to utilize Varispeed for recording guitar on an audio rail. After recording a guitar part with no furnishings at approximately xv-20% of the original tempo I hear a 'wobbly' effect on the guitar part when returning to the original tempo. Any ideas what is wrong? I never had this problem in Logic ix...but X.

Thanks.

I am trying to utilize Varispeed for recording guitar on an audio rails. After recording a guitar part with no effects at approximately fifteen-20% of the original tempo I hear a 'wobbly' event on the guitar part when returning to the original tempo. Any ideas what is wrong? I never had this problem in Logic 9...merely X.

Thank you.

Happens to me nine all the time. I have to utilize Pro Tools for those kinds of parts and so bring the tracks back into Logic,

having same event. again but x not 9. Happens in middles of project. only when record enable is on every bit well. not when only hit 'play'.

Aye...I just tested information technology again in Logic 9...non having any of the bug I am having with Logic 10. This has to exist a bug.

Hm what buffer setting for io?

128

Would honey to go this sorted out as I have had to motility back to Logic 9 because of information technology.

Well I recollect varispeed & flex work in realtime, though it's been a while since I used vari. When artifacts appear increasing the io buffer size was the gear up iirc...? Same thing seems to employ to flex pitch under LogicX now likewise btw.

128 is pretty loftier for recording in real fourth dimension. No?

Posted on a bunch of Apple/Logic forums and nobody seems to know.

The issue isn't recording though, it's the background process (thread) responsible for varispeed/pitch (and flex pitch etc). If you're doing a big change and the buffer size is as well small-scale the algorithm may not take enough information to work with efficiently...Attempt it and see?

Thanks. Will requite it a shot.

right off the back that worked in a new project that was made from a template of a project with the issue in information technology.
Haven't tried the onetime project that originally started the problem.

increasing the buffer size fixxxxxed so far. So thank y'all.

No problem, don't forget to freeze when you have results you're happy with then y'all can offload the functioning penalty (and perchance go back to a lower buffer if yous need to do more tracking).

Thanks, Valis.

Your suggestion worked. I can at present apply Varispeed within Logic X. No need to record in Logic 9 anymore.

So can yous clarify?

When y'all record at a lower speed in Varispeed, you are supposed to increase the buffer size (making it harder to play)? Or is this but on playback....look...no Logic is always at a loftier buffer on playback...yikes..I'm confused...

thx

I tape at 128 with Varispeed engaged and then when I am done recording I plow off Varispeed and return to 512. No problems.

But as an aside...I have to mix at at least 512 since I am using a UAD satellite, merely, this has aught to exercise with Varispeed.

Hope this makes sense.
