Which modulation routing method would you recommend for my project?

@David-Healey

He means the rate at which the LFO actually updates the DSP it's connected to, I assume.

This does vary in HISE and affects the sound of High Rate modulation.
I haven't measured every path myself so I cannot give a breakdown here.

But it's definately possible to do a sweep with a good AI agent, or use the REST system to probe all the Hise processing paths and get the exact numbers for all the different scenarios.

I started to do this myself, but I haven't covered all of them and I'm using lots of custom nodes, where HISE allows you to set the rate of modulation yourself and so this isn't so unknown.

What I do know is that HISE doesn't seem to go faster than updating DSP every 8 samples.
I might be wrong on that point but that's what I've observed for C++ nodes anyhow. Maybe it's different for native DSP.

Not sure, that doesn't jive with what he wrote.

@David-Healey Really? He's talking about block and frame sizes though? DSP usually reads parameter values at the start of each block. Using larger blocks means you might not be reading the parameters / LFO modulation as frequently. (assuming the modulation / parameter callbacks are also being called fast enough by the modulator)

I only see that in Method 4, but he's mentions "fidelity" and "Resolution" in method's 1 and 3 as well.

Hey guys. I do indeed mean the speed of the LFO modulation.
I should have been more clear.

Slow methods like the global LFO to cable will sound mushy and uninteresting at speeds higher than 20Hz. Native LFOs add some nice audio rate modulation distortion at those speeds, which the other methods do not.
At least the way I've set them up

@observantsound What about using global LFOs and global modulators, this is what we did back in the good ol' days before global cables. :)

I have no idea what that means, sorry. Could you explain?

I used the fix_block8 node and put my oscillator inside of that container. But at 40Hz the native LFO to Filter Cutoff still sounds better than doing the scriptnode LFO to filter.

Here's the Scriptnode LFO I built
TimeVariantLFO.xml

@David-Healey I thought that's what I did in method 3?
Can you route global LFOs in Global Mod containers to various targets without global cables?

Nope, method 3 uses cables.

Yes. I'll make an example for you

[David Healey]

@observantsound Here's a simple project that shows how to dynamically assign a modulation target. The combo box in this case allows you to assign the global lfo to either gain, pitch, or filter frequency. You can play with this example and expand it to connect the lfo to more than one target at a time.

As you scale this up for a full size project you'll need to plan how to keep things organised otherwise it will get messy.

@David-Healey thanks David! I’ll check it out before the end of the week and get back to you.
