It's Korg PA4X. As most know it belonged to my friend DickieT, but I've using it for nearly two years. It seemed like the thing to do was buy it. Now he can pay for his SX900.
I've tried for months to find something that I feel is as good for my use as the 4X, but haven't been able to do so. SOOO, it will remain my number one tool. I will take extra drugs to help my right hand problems.
For now, the EA7 will remain my backup/second team arranger.
