The core of my stage rig for keyboards remains a Hammond SK61 with a Korg Kross above it. Between them, those two can deliver pretty much everything I need in both my 5-piece soul band and my 7-piece functions band ... in both of those I supply piano, organ, strings, brass and synth, plus occasional weird 5hit like banjo, accordion and mouth organ.
BUT that's "everything I need" rather than "everything I want".
Solution? The Yamaha Reface series. https://www.soundonsound
