Midiverus is a concept that allows calling any midi hardware that connected to the computer without any involvement from the D.A.W side and connecting it to any VSTis that are opened in the D.A.W via midi channels. In that way, you can connect to any opened VSTi as many midi hardwares as you wish (for instance, both your midi keyboard and midi controller to control playing and knob tweaking separately). Each route is connected to it's own unique on\off pad which can allow the midi signal passing to it's address or just switch it off. You can also determine which of your midi hardwares gonna internally control the pads.
Demo limitation for Midisquid: 3 seconds silent every 15 seconds.
