If I count the ones back in the storeroom, I probably have at least 25, although I can't guarantee that they're all in working order (some haven't been turned on in years (VP550, JV10,Chroma, DX7,TX16,SY55,U20,etc.,etc.). There is also a mountain of PA gear and recording/gig accessories. This is the main reason I can't bring myself to downsize (house). BUT, I assume you're talking about currently in-use keyboards. That would be, in no particular order: 1. Nord C1. C2D sold after I stopped gigging. 2. Yamaha Motif ES 3. Fantom G7 4. Triton Classic 5. Roland A-70 6. Roland VP770 7. Alesis VX49 8. KeyB Duo MK111 9. Yamaha Acoustic piano
Modules: 1. Korg O5R-W 2. Sonic Cell 3. Roland SC88 4. Korg i5M
As to the WHY; because 1. I'm a techno-geek, 2. I'm a pack-rat, 3. I've always liked experimenting with alternative sounds, and 4. It's nice to have an 'arsenal' if you're into recording.
