Roland has built one packed instrument to celebrate 50 years of the company’s synths. The SH-4d sports eleven synth oscillator models in one box – from SH-101 and JUNO-106 to new cross FM and wavetable synths. But it’s still hands-on, battery-powered, and costs US$649. And there’s a twist, literally: D-MOTION motion control means you can pick up the synth and play it by moving it around.
