I decided to get all the available upgrades for my new-to-me Kurzweil PC3 since who knows when they'll be discontinued. Well, technically the Kore 64 probably is already. Besides I wanted it to be "maxed out" before it's my only board for six years!
So...I bought the Kurzweil Kore 64 ROM expansion... - I don't like the stock horns much and this has lots of new horns among other things.
...and the Kurzweil PC2SRIB ribbon controller.
