VST host designed for live performing

I would like a powerfull and flexible VST solution in Cubase for triggering samples, doing MIDI mapping (keyboard to sound generation), keyboard splits, etc. special designed for live performing stage musicians. Easy to bring my studio workflow with Cubase to a clear looking live GUI.I’ll be using Cantabile performer pro for this but it is’n t that userfriendly and stable for Steinberg instruments Padshop pro and Retrolog wich I use quite often. Beside these applications I use NI Komplete (11) and GSi VB3, SQ8L, Taurus on stage.
