Thank you for the clarification, @andrei_olenev.
A modulator opening the whole Grid sounds overkill but at least is conceptually simple. A simplified version of The Grid complicates things a lot because… what do you include/exclude in this version?
Right now there is no way to save custom modulators, is it? This means that this part of the functionality would need to be added, with or without Grid.
Wouldn’t it be better to have a modulator capable of “loading” any Grid (FX?) preset and use any values in it? This way you would collect Grid (FX?) presets (something you can do today) instead of custom modulators (which don’t exist yet).
