The keyboard player in my band has a Yamaha keyboard (not sure of model) but it doesn't really sound all that good. So he's looking to upgrade to a better synth. He said he prefers analog, but isn't bent on it. The problem is, nobody in the band knows much about synths, and he doesn't have too much to spend. Maybe $500 max. I was thinking, instead of buying a completely new synth, couldn't he just get a synth module and plug his current keyboard into that? Another idea that came up was plugging his keyboard into his laptop via MIDI and getting some sort of synth program. Is this a viable option? Anyway, if anyone out there has any suggestions please help us out.
