Scriptnode LFO shape

[d.healey]

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

[Matt_SF]

@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).

[d.healey]

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.

[Matt_SF]

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

[Matt_SF]

@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.

[d.healey]

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

[Matt_SF]

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

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

[Matt_SF]

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

[Christoph Hart]

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

@Matt_SF @Christoph-Hart Thanks! How did you add those annotations?

[Christoph Hart]

Rightclick on a node, then enter it in the comment field. It supports markdown syntax

[ustk]

Here's how I do it

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 ;)

[d.healey]

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?)

[ustk]

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

[d.healey]

@ustk

Are you using new_layout?

Yes

[d.healey]

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.

[d.healey]

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

[ustk]

@d-healey Built new_layout but it crashes too with your snippet...

[d.healey]

@ustk Yep, my snippet crashes here too :p I'll post a new one when I'm back

[Christoph Hart]

@d.healey Your snippet contains a network that was saved to a file, so it can't find it (crashing is not the smartest hint though).

However I still need to think about a good solution to share scriptnode examples (including SNEX files)
