@dane-zone it might be that you just need to save the scriptnode network once you load in the snippet, then go to compile it.

Are you able to create a scriptnode network with just a simple oscilloscope then compile and load it into the hardcoded fx?

You also don't necessarily need to use the hardcoded fx, you can work with just the script fx.

@dane-zone click the little dropdown in the node title to expose the parameter of the dynamic blocksize so you can change it.

The CPU meter in HISE is not the final thing. Depending on the complexity of the network, it may go down, sometimes a lot, when you export it. So export it and check against other plugins in your DAW. That's your reference.

If there are no audible artifacts at lower modulation values, you could leverage the dynamic blocksize node to go for frame processing only past certain modulation thresholds, optimizing the plugin when low modulation values are used.

There's gonna be a "hiccup" when you switch blocksizes, so keep it in mind if you want to offer parameter automation of the modulation frequency. You may wanna leave an option for this in the settings but before you go trough the engineering trouble to offer this feature, export the plugin and check whether using frame processing for this is actually even expensive by comparing it to the performance of similar plugins on the market.

@d-healey Idk what happened but it's working fine now. I switched to having MPE off by default in most presets which seems to cause less trouble even if it is switched it on later.

Haven't been able to try release start yet but looking forward to trying it on a new project. The samples I'm working with are pre-edited from an older project so I'm essentially forced to go the old way for now.

@dane-zone The Choke Group i meant to work between two different Samplers, not within the same sampler.

@dane-zone Yes scriptnode is probably the easiest way to go here, and there is an example implementation of a vibrato in ScriptNode here: https://forum.hise.audio/topic/4952/scripnode-101/13
Modulation signals don't produce sound, they modulate an audio signal, so stereo modulation is not possible.

Vibrato is just modulating the pitch, so unless you wanted to modulate the Left and Right channels separately there is no reason to process the channels differently. If you want to do this then follow the vibrato example above, separate the left and right channels, and add independent mod sources and delays on each channel (Left and Right).
