Wow! That's the best $800 you ever spent! New, when it first came out, I paid over US$2100...

Try the SN Jazz guitar and the SN Steel and Nylons. IMHO, the most playable articulated guitars short of software ones. No velocity triggered articulations, you do it all with your playing, the way it works best! That War piece that kicks off this thread features the Jazz heavily.

Give the SN saxes a miss, though. Yamaha's are better, IMHO (see? I can accept when other brands do things better! LOL).

The BK-9 has its own sound, it's not a Yamaha, it's not a Korg... Find what it does best, it will amaze you. Try to make it do what it doesn't, it won't! Enjoy, and never let it go. At that price, you can afford to hold on to it! The world is full of people that let arrangers go that now regret it, especially brands that stopped making them. The BK-9 is the most advanced arranger Roland ever made. And ever WILL make...

It's the last unicorn. Treat it nice!
