Scriptnode glitches



  • Hi Folks,
    I'm (always) fooling around with scriptnode modules, and i'm trying to get something like a chorus-y effect.
    No matter how I set up my nodes, as soon as I'm modulating delay nodes, I end up with noise and glitches. I'm using a smooth parameter node but that tames the effect. Also tryed with oversample & block nodes but that doesn't solve the problem.
    Maybe this kind of effect has to be done in SNEX ?
    Anyway, I wanted to know if someone has insights about this.

    Here's the snippet :

  • @Matt_SF core.fix_delay, is a fixed delay... So it's not meant to be modulated so it's normal you get glitches. For modulation purpose, you have to use a stk.delay_a



  • @ustk Yes I used the core.fix_delay only to delay the processed channel. In this example I used the jdsp.jdelay node but there are also glitches when using stk.delay_a... 😕



  • @Matt_SF Yeah I'm not sure the jdsp.jdelay is meant to be modulated but I've never used it...
    You're right that the stk.delay_a has some glitches too, but it sounds like aliasing. So it's a bit better to oversample. Although a 16x oversampling doesn't fix entirely the problem. And moreover, to compensate for the oversampling loss in the delay time, you need to increase the delay max (in this example I'm going to 400). So the glitches are back, but a bit less. Still, it's far from perfect. Since the aliasing increases with the speed and the amount, it's better not to push the parameters and use more delay lines (chorus effects generally have several delay lines so it's normal that you can't achieve a nice chorus with only one anyway).
    Is it possible to totally remove the glitches or if it's a Hise issue in this case, I don't know...

  • @ustk Ok I see. I'll mess around with these to see what comes out, and I'll post the result if I can come up with something nice.
    Thank you for your help, I really appreciate !
