Just for example you may be using something like the Waveshaper2B and want to allow the user of the VST to switch between different equations to change the wave-shaping effect.
There’s no need for any elaborate structures using PatchMem modules where you need to convert between GUI and DSP. It’s all easily done with GUI modules.
All we need is our pre-defined strings saved in the Fixed Values(Text) modules, and a drop down list added to select the required equation.
Don’t forget that by re naming the plugs on the switch module you’ll create a list of names to select from in the drop down list, otherwise you’ll end up with a list filled with “Spare”.
