Looking for a certain type of pitch-shifter plugin

[KTlin]

Hi

I'm looking for a plugin that can pitch-shift the incoming signal but without using a granular-type algorithm for the time-stretch, because I don't need the pitch-shifted signal to preserve the same tempo as the input signal. In other words: I need something that behave like a slow-down (or speed-up) tape-machine, ie when you raise the pitch 3 semitones for example it will also speed up the material and when you lower the pitch it will slow down the material.

Cheers

you could use a sampler for example in ableton, or are you looking for strictly an insert effect?

[KTlin]

Yes, I could use a sampler, indeed, but an insert effect would be a much quicker and simpler solution.

you cant play something faster than it is in realtime.

Indeed, playing it faster can't be accomplished in real time, it would have to use some kind of buffer for speeding up the material.

You can do that with a free plugin called Kammerl Kaske KKPitcher, and you might also find his strange collection of plugins useful for other weird effects.

KKLooper, KKScratcher, KKSlicer, KKWarmDist.

if you want to use Kammerl Kaske KKPitcher on your voice in Real-Time, then drag a blank / silent MP3 into your DAW and set the blank / silent MP3 to play on a loop infinitely.

problem with that is you cant predict how long the buffer needs to be, it basically needs to be as long as the plugin is active for. Its going to have to be huge, and thus a potential problem for latency compensation implementations.

Existing plugins with exceptionally long buffers might be, what 8192 samples? You'd basically need ten times that for each 2 seconds (one bar at 120bpm) of mono audio at 44K. Betcha that breaks a lot of DAWs.

If you modulate the delay time of a simple delay, you can get that effect. Its the same principle used in granular pitch shifters, just with way longer “grains”. I once made something like that in Max/MSP. That patch could possibly be turned into a M4L device…
Actually if you start with a long delay and shorten it, you would get a speed/pitch up in realtime… One could try a sort of sawtooth modulation synced to the tempo…

Cableguys Shaperbox Timeshaper will do this I think

[KTlin]

Thank you for all the recommendations guys!

Cableguys Shaperbox Timeshaper will do this I think

Ah, yes! I forgot about the Timeshaper. It pretty much does the trick. The only drawback is that it's not at all intuitive to pitch the signal up or down a certain number of semitones other than 12 or 24. For example, what curve should you draw if you want to pitch down the input by 7 semitones?

You can do that with a free plugin called Kammerl Kaske KKPitcher, and you might also find his strange collection of plugins useful for other weird effects.

I didn't know about Kammerl Kaske plugins but I downloaded the KKPitcher and tried it. It indeed is pretty much what I was looking for. Unfortunately there are two drawbacks: the pitch shift (using the pitch slider) is done in percents, not in semitones and I would prefer to have it in semitones. The other drawback, which is much more nasty, is that the plugin seems to be buggy. I tried it in Live and in Bitwig and in both cases every time I re-open the interface all the parameters reset (they all go back to the default state) and this obviously makes the plugin completely useless.

problem with that is you cant predict how long the buffer needs to be, it basically needs to be as long as the plugin is active for. Its going to have to be huge, and thus a potential problem for latency compensation implementations.

Well, both those plugins mentioned above (CableGuys Timeshaper and Kammerl Kaske KKPitcher) can pitch-up/speed-up the material (using a buffer of one bar or more, as far as I can tell) so it seems it is possible.

Waves SoundShifter effect plugin?

When the Time and Pitch ratios are the same, the SoundShifter will perform as a high quality vari-speed re-sampling tool.
