Scriptnode LFO shape



  • Anyone know how to make a rounded rectangle LFO with scriptnode?



  • @d-healey Interesting. Mixing modChains seems to work ☺

  • @Matt_SF Thanks, I'll play around with this!



  • @Christoph-Hart Feature request - make core LFO gain default to 0, I keep deafening myself each time I add one 😛



  • @d-healey said in Scriptnode LFO shape:

    @Matt_SF Thanks, I'll play around with this!

    I noticed sometimes phase issues happens when changing things around. It seems to work better if you put the 2 modChains in a split note (and sync the frequency parameters with a global parameter knob).



  • It seems to be quite hard to keep them in sync, if I start making changes to some of the parameters I lose the shape and can't get it back.



  • @d-healey I can't try it right now but a control.resetter might work...



  • @d-healey Didn't try much, indeed control.resetter works but actually it might be unnecessary : putting the two oscillators one after the other also works and they seem to stay in phase. No need to bother with a convoluted send/receive system.

  • @Matt_SF I like the simplicity! But your snippet is giving me this:

  • @d-healey That's odd, it's working here :

    98546e1f-7ff7-496b-b66c-f6edaa2bdbf5-image.png
    Maybe having a parameter to reset the oscillators' gate once in a while is worth having after all... ?
    And the oscs do seem to stay synced when changing their phases btw
    Edit : and which osc's phase you choose to change doesn't matter, the end result is the same



  • @d-healey About this case : just inverting one osc's phase gives you the rounded rect wave.



  • Here's another approach using a math.expr node with the Math.smoothstep() function and a single triangle oscillator that is being rectified:

    using a math expression is less convoluted...
    But the cool thing is that you can go linearly from sine to rectangle just by using the Gamma parameter 😉



  • I've built up Christoph's example into a larger module. I'd now like to include a fade in time to the LFO. I've added an envelope and tried it in various places in the chain but it doesn't work as I want.

    Any ideas?

    Also, how could I add some random variation to the frequency value? (another math node? or could I feed my noise osc back into the freq of my triangle osc?)



  • @d-healey Are you using new_layout? Because the snippet crashes on develop...



  • @ustk

    Are you using new_layout?

    Yes



  • Also, is there a way to get the Math.expr node with the smoothstep to be bidirectional? Currently it always goes from 0.0 - 1.0 but I'd like it to go from -1.0 - 1.0

    Actually I think I can work around this by editing the modulation table.



  • Also also is there a way to get LFO to restart on keypress, so every note in a chord stays in sync?
