The D-50 is a very interesting digital synth that combines PCM samples with Roland's linear arithmatic synthesis method, a style of digital subtractive synthesis. The PCM samples are providing the attack sound and the LAS section will ring out or sustain. In practice some very lovely and complex sounds are easy to achieve with the D-50.
This synth is in great shape and works perfectly with just some minor cosmetic wear for its age. Includes 4 extra rom cards as pictured and original AC power cable.
