Just bought a Roland SH-32 synth. I love it! So easy to use, brings back memories of my old Arp Odyssey (?sp?)!
I considered the Novation "A-Station", but I like sliders better than knobs for some things, and the SH-32 has lots of sliders, plus plenty of knobs/buttons to control things. Oh yeah, kind of important: it Sounds great too!
