Anukari has long had a modulation system, with LFOs, host automation controllers, MIDI, etc. But adding modulation to a preset has always been a kind of labor-intensive process. And one big gaping hole in the UX was the lack of a way to bind a knob inside Anukari itself to allow modulation to be controlled via the mouse.
The lack of mouse control was a hassle, but the problems were a bit deeper than that. Because of this issue, interfacing with the DAW was always not quite the way users expected. For example, in FL Studio you can choose an automation via the learn feature by "wiggling" a knob inside a VST plugin. FL Studio watches and sees which knob was wiggled and binds it. But of course with no mouse-controlled knobs inside Anukari, this was not possible.
Furthermore, while it was possible to map host parameters to automations inside Anukari, they could only be controlled via the DAW, which is really inconvenient, and often is a really weird workflow. Users expect to be able to hit "record" in the DAW and then go play the VST, knobs and all, and have everything recorded.
