The Roland GAIA SH-01 Digital Synth channels the classic analog sounds from the company's past into a slick, modern package made for today's players. Featuring 37 velocity-sensitive keys, the SH-01 is built with three separate synth engines each with dedicated oscillators, filters, LFOs, and more. The result is a wide-spanning 64-not polyphony playing experience that travels easily and won't break the bank.
