My homie got a Roland D2 Groovebox that he said he'd sell to me for 50 bucks. Is this a good price? I seen it on Ebay going for about 165 used, so Im guessing it is. But is it useful at all? What kind of shit can I do with it? Can I control it with a MIDI keyboard? Can I use it in conjunction with a PC sequencing prog? As you can see Im new to the game... would a beginner like me benefit from this thing? It looks kinda tight, but its bright ass orange and shit. Any info would be appriciated!
