I made some great experiences with this combination of the Multi/Poly rack version and the KORG Keystage 49 masterkeyboard with MIDI 2.0. The feel of the Keystage 49 keyboard is quite tight - that is my impression. I like the poly after touch, especially when I play some of my Vangelis inspired pad/lead synth combinations of my multi/poly soundpack Synth essentials Vol.1 You can see the combi of both in this video clip:https://youtube.com/shorts/H1BR6G6cUx4?feature=share
