Timestretching/Pitchshifting

@johnmike I've never used it, but I don't see why you could use a slider to control that value.

Groups can't be routed though (at least not yet, it's on my wishlist), so you're not going to be able to send each set of samples to different effects.

I think you're better off nagging Christoph to solve the bug with multiple samplers going out of sync. Perhaps provide a snippet or demo project that demonstrates the problem.

Christoph Hart

Have you supplied a valid NumQuarters property to each sampler?

johnmike

@Christoph-Hart I've tried them at different values...same results...ive changed all of the numquaters to 0 ive tried 2,4,8 etc etc...if all the samples are in the same sampler and the numquarters are set to 0 everything plays and syncs fine...but when I mix multiple samplers it falls apart...working on a video now

johnmike

@Christoph-Hart here's a vid with time stretching the loops all in 1 sampler...numquarters at 0

@Christoph-Hart and here's a vid with the kicks moved to a different sampler...numQ's at 0,4,8 just playing around with it...but as you can see they slowly drift out of time with the click...

sorry for terrible audio it's coming from the built in mic...but should be loud enough to hear what's going on

The Timestretching/Pitchshifting is nice, but causes a cpu spike on my set up... is this happening to anyone else?

Only asking so I can know how to proceed with the project im working on.
thx

Sawer

@BWSounds Same here... Cpu spikes to 60% sometimes. Only tried on FL studio tho. Have not tried on mac yet.

Christoph Hart

@Sawer if you're using the SkipLatency parameter then yes, there will be spikes when you start voices, otherwise the CPU usage is high but not unreasonably high.

Hi! I have a problem with the timestretching. I have updated my HISE version(3.6.0) but the functions Sampler.getTimestretchOptions();
Sampler0.setTimestretchOptions(obj);
Sampler0.setTimestretchRatio(0.7);
are throwing this error message:
Interface:! Ui_samples.js (13): function not found {SW50ZXJmYWNlfFVpX3NhbXBsZXMuanN8NDM2fDEzfDQ3}
Could someone help me to solve this problem? Thank you

// Get sampler
var Sampler0 = Synth.getChildSynth("Sampler0");

// fetch the current state
var obj = Sampler0.getTimestretchOptions();

// print out all properties
Console.print(trace(obj));

// Apply your changed
obj.SkipLatency = true;
obj.Tonality = 2.0;

// Update the options
Sampler0.setTimestretchOptions(obj);

//Set ratio
Sampler0.setTimestretchRatio(0.7);

@Lumi283 The time stretch functions are part of the Sampler class, your reference is of the ChildSynth type. You either need to use Synth.getSampler() instead or use Sampler0.asSampler...

Lumi283

@d-healey Thank you it's working!
Now when i want to channge the tonality nothing happens.... But the tonality was changed in the JSON.
Interface: {

//Script
var SamplerX = Synth.getSampler("Sampler0");
var obj = SamplerX.getTimestretchOptions();

obj.SkipLatency = false;
obj.Tonality = 6.0;

SamplerX.setTimestretchOptions(obj);

Console.print(trace(obj));

//Console
Interface: {
  "Tonality": 6.0,
  "SkipLatency": 0,
  "Mode": "VoiceStart",
  "NumQuarters": 0.0,
  "PreferredEngine": ""
}

Any idea ?

Christoph Hart

@Lumi283 tonality is between 0 and 1.

Lumi283

@Christoph-Hart
Okay, I understand, and what values correspond to semitones?

johnmike

@Christoph-Hart any luck with time stretching across multiple samplers? or is it something im doing wrong?

Christoph Hart

@johnmike I‘m on vacation at the moment so I can‘t check stuff with actual audio but I‘ll take a look when I get back.

d.healey

@Lumi283 Try dividing 1 by 12 (if it's linear, I haven't tested it).

What, do you also take time off sometimes, how will we manage?

johnmike

@Christoph-Hart definitely enjoy your vacay! I can wait lol...was just wondering...sorry to bother! thanks for all you do!

d.healey

@johnmike I just tested and it seems to work fine (I notice that if I set the tempo too high it loops back to a slower tempo which is weird, but that could be a Linux thing).

Here's a video I made

Here's the audio file I'm using in the video

I left numQuarters at 0
