Hi Kim,
finally found the time to give this a go yesterday in tracktion.

speed setting certainly makes a difference (but still subtle). I only used it on vocs, and felt there are too many artifacts / processed phasey effects to do the vocs justice. Will try it in others ways.

Also found a problem when rendering. Tried to do this incase I achieved a more pure tone result, but it caused InTune to crash each time. Firstly, rendering took forever!! Ended up taking a 5 second voc clip, which took a few minutes to render. After rendering however, Intune ceased to function, even as a new insert, although levels still functioned. Link errors came up in the dialogue box, and had to restart tracktion to get it to work again.

any suggestions?

Dan

Speed certainly

for the mac version you could try using tristan jehal's shifter~ external

Formant-happy, pitch-synchronous-overlap-add-based (PSOLA) pitch shifter (for monophonic pitched audio only)

Hmm. Do you have the latest version? I can't imagine why that would happen. We've got other people running CarToon in Tracktion.

I've got CarToon running on my computer in Tracktion and Cubase SX 2.2, with multiple instances and rendering.

I suspect it might be a strange incompatibility with Pluggo runtime. Try downloading the full Pluggo demo and try out some of the other Pluggo plugins to see if they work.

Sorry about the hassle.

Forever,

Kim.

I'll keep it in mind, but I'd rather not have the Mac version sound different to the Windows version.

It would be nice if Paul Hill could part shifter~ to Windows.

Ahh - hadn't realised there was a newer version (with betabugs graphics) i'd checked their site but it's not up yet. will have a go with this one tonight.

It's still beta, and there's still at least one change I need to make before it goes 1.0. It'll be on the Betabugs website and there will be proper press releases when everything is ready.

Not everything is ready yet.

However, the core algorithm is not likely to change between now and the 1.0 release. Of course, it's beta, so the usual disclaimers apply.

4096x4, i think, in the .DLL i posted.

at anything over 1024, you can hear the 'smearing' in the time domain as a slight reverby effect, but at anything less than 4096 you don't have enough frequency resolution for quality/clarity...

again, with less than 4x overlap the actual bin frequency estimation is too vague, but at 4 or 8x overlap things get audibly phasy...

some people have suggested using variable FFT sizes to get around this... i've tried some experiments (eg different FFT windows for high and low frequencies) but haven't, so far, got it to sound any better... so i'm going for resampling/interpolation in the next version.

hi

I tried CarToon with a vocal track in Cubase SE and I only get badly distorted sound. The speed control and midi don't change anything. Any ideas?

Host? Platform?
Latest Pluggo and Quicktime?

Have you tried CarToon? What are your thoughts on the pitchshifting in CarToon?

Hmm. I don't know. All I can suggest is downloading the full Pluggo demo to see if that works. If it doesn't work, then it's a problem with the Pluggo framework, and unfortunately it's out of my hands. If the full Pluggo demo works, then it's a problem with my plugin, and I'll have to have an extra hard look...

Forever,

Kim.

Which flavour of Cubase SE? 1.x? 2.x?

I purchased the System2 pack in last december so I guess it's the latest version.

I'm not at my DAW now. I'll check the specs in the evening (GMT+2).

Problem solved! I increased the latency a bit and CarToon started to sound like I think it should. So it was a performance related issue.
