...been searching for a Mac application that would give the user real-time control over the pitch of soundfiles. It's needed this for live application, so the real-time capability is STRESSED. Ideally, something along the lines of a turntable-like interface, as that's the closest approximation I can come up with to my actual intent. And the gradation has to be fine, as I'm dealing with some sort of precision here. I've been playing with Hyperprism for a bit, but the algorithm works on a two-dimensional scale, which leads to a lot of unwanted artifacts (i.e. not the background anomalies the 'Bucket Brigade' thread has made us all learn to love...). Any suggestions would be welcome. -Keith. np- EBN E SYNC (wordsound). Track #5 has to be the best thing any of those 'WE' lads have committed to tape. The lack of a vinyl pressing is a crime. __________________________________________________ Reckankreuzungsklankewerkzeuge.________________________ _________________________________PO Box 382864-2864 Cambridge, MA 02238-2864____________________________ _______________________________________________USA _______________Main URL: http://www.tiac.net/users/sheket __________________________________________________

read your hyperprism manual again. you can set the time range to 0/0 which means that only the pitch axis has any effect on the sound. hope that helps.

You might want to explore a program called ACID by the fine people at Sonic Foundry. It seems to be something fairly close to what you're looking for.

Absolutely. SD 2's scrub mode is great for this (though you do have the limitation of it being ram-based to contend with) but for shortish 'digital scratching' it's quite cool. To

quoted 1 line emulate turntable-ish slow downs or speed-ups,

>emulate turntable-ish slow downs or speed-ups,

there is an Audiosuite plug-in for ProTools called Vari-Fi (from Digidesign) that does just this, unfortunately it does ONLY that. It is supposed to emulate a TT slow-down and you can't vary the rate of slowdown / speed-up, or scratch or whatever. But if you are looking for an 'authentic' TT slow-down it might do the job (i haven't played with it much) martin wheeler paris france ps - attention, shameless plug follows. For an example of excessive use of SD 2 scrub-based digital scratching, check out the 'Hornithology' track on Rhys Chatham & Martin Wheeler 'NEON', Ntone Records: NTONE CDS15

I found sort of what I had originally intended to find, if anyone's interested. It's a vari-speed CD player-emulator called Retro CD 1.5. A demo is available at various points throughout the internet (try MIT's hyperarchive), which allows for 4 hours of occasionally interrupted use upon installation, before registering for $10. It will buffer, then play audio directly off of a CD at a variable rates from 200% to 0% at degrees of %0.001. I burned a CD of some looped audio, then tooled for a bit, mixing it with records and such. Really handy for the live. Thanks for all of the suggestions, though. I think I will check out that Var-Fi plug in, Martin. You've managed to coax some great sounds out of it. -Keith __________________________________________________ Reckankreuzungsklankewerkzeuge.________________________ _________________________________PO Box 382864-2864 Cambridge, MA 02238-2864____________________________ _______________________________________________USA _______________Main URL: http://www.tiac.net/users/sheket __________________________________________________
