On my trips overseas, I play a "house" digital Yamaha for dinners. For cocktail hour, I play a jazz guitar and a JazzKat amplifier.
I have no back-up keyboard, in case something happens to the Yamaha.
Considering portability, would the Korg Microarranger be an appropriate back-up? I could put it on top of the Yamaha to "sweeten" the piano sound and add variety, and use it directly into the JazzKat for portability and as a back-up.
What do you think? Cost is not a factor...I "ain't paying".
