Octatrack Time Stretch vs Dedicated Time Stretch Pedals

[natron_mn]

Recently got a Digitone, and I’m loving it so much I’m very much considering an Octatrack.

I’m primarily a guitarist, who plays a lot of effects, and I love a good time-stretch effect. I’m wondering if the time-stretch option on the OT is “better” than dedicated time-stretch pedals, like Cooper FX Outward, Red Panda Tensor, Pladask Fabrikat. Or, is the time stretch option on the OT pretty basic, and a dedicated pedal would be more useful?

I’d love to use the OT as a live signal processor for guitar in addition to its many other uses. And to help fund an OT, I’d probably sell off my Tensor… if the OT can do a convincing time-stretch.

(Or, does time stretching on OT only work on recordings rather than on live signals?)

Hi. OT is a great realtime fx for guitar, and you can use recordings immediately, hence timestretch (on recordings only, but in live conditions). Not the best timestretch, but it can be creative.

Guitar only straight in OT, “drums” are guitar signal processing

OT timestretch quality

Hi, I’m quite new to the OT and I’m experimenting with it. One of the main feature that lead me to buy an OT was timestretching, but I’m not really convinced by it… Compared to Ableton’s one, the OT’s timestretching is not very clean and artefacts seem to appear quickly when slowing down a sample. What is your opinion ? Am I doing something wrong ?

Octatrack | pitchshifting timestretch quality

i just wonder how good the pitch shift and timetsretch algo of the octatrack works with different kind of audio material. iam thinking of speech, music (polyphonic and monophonic) sources and unvoiced / noise sounds . over the years i mostly used ircams supervp for max with superb results both for pitch shifting and time stretching. how good is the ot in this respect? anyone here made direct comparisons with software based algos?

Wow, the guitar processing in the last clip is really good. The shimmer in the second is wonderful too.

I could see the time-stretching in the first clip being usable in some instances, but yeah, it does add some weird artifacts.

Thanks for the reply!

but yeah, it does add some weird artifacts.

I layered several instances of the song, played with different speed hence phasing and artifacts. Totally exagerated settings.

Anyway I don’t especially like timestretch in general, but some freeze fx are totally usable with OT.

Do you have sound examples of what you’d like to do with timestretch ?

[natron_mn]

I don’t really have examples. but if you look at the time stretch demos in the following YT demo of the Cooper FX Outward, that’s what I’m after. That may be a little ambiguous.

Or ambitious ! Cool fx !
I’ll try to mimic it.
