Time Stretch SkipLatency working?

[DanH]

I'm not experiencing any benefits of using SkipLatency.true... Not sure if it's working, doesn't seem to in a simple test but perhaps I'm doing it wrong?

Below is a snare sample unprocessed at the top, then SkipLatency true, and at the bottom false. Both true and false have the same latency and use the same cpu in HISE itself.

@DanH friendly bump! Has anyone used the timestretching capabilities yet?

[DanH]

@Christoph-Hart here's the trace...

  "Tonality": 0.0,
  "SkipLatency": 1,
  "Mode": "Disabled",
  "NumQuarters": 0.0,
  "PreferredEngine": ""
}

Does it look correct? Weirdly it says "Disabled" when actually it's on, as per below:

Was really hoping to implement this into the next update...

@DanH I don't see anywhere in your snippet where you are changing the skip latency setting.

[Christoph Hart]

yup dave is right, you need to call Sampler11.setTimestretchOptions(obj); after changing each property - obj is not a smart thing that notifies the sampler but just a plain old JSON object so changing its properties will do exactly nothing until you send it back to the sampler.

[DanH]

@Christoph-Hart ah ok, gotcha!
