One careful owner, this classic keyboard is in mint condition and has never been gigged, having spent most of its latter life in bubble wrap. In full working order with user manual. About the keyboard : The JD-800 combines sample playback with digital synthesis , a process that Roland calls Linear Arithmetic synthesis , a technique Roland had been using to great effect in the Roland D-50 . The JD-800 has 108 waveforms built-in, but these can be expanded via PCM-cards. There are waveforms in a variety of categories, like; analog synth, acoustic instruments, like guitars, woodwind, brass and voices. Most of these waveforms are very short and are designed to give character to the attack portion of a sound, while some longer ones are designed for creating pads, or the sustained part of a patch. The JD-800 was the first instrument from Roland to have its core sound set of waveforms developed entirely in the United States, under a short-lived branch of Roland's R&D-LA office in Culver City, California.
