The Roland JX-10 Super JX is a 12-voice analog synthesizer keyboard produced by Roland Corporation from 1986 to 1989, along with a rack-mounted version, the MKS-70. For nearly 30 years, it was the last true analog synthesizer made by Roland and has been critically acclaimed as one of their classic analog instruments. In 2015, Roland once again started producing analog synthesizers beginning with their JD-XA and JD-Xi keyboards as analog/digital crossover synthesizers. The design on the JX-10 is essentially two Roland JX-8P synthesizers put together, with a 76-note velocity-sensitive keyboard with aftertouch. It also includes features not found on the JX-8P, including a simple 1-track sketchbook sequencer and a delay effect (which works like a "MIDI delay" by delaying one tone rather than acting as a true DSP delay effect). However, the JX-10 is not exactly the same as "two JX-8P's" because the chorus is not identical to the JX-8P (hence the chorus sounds different between the JX-8P and the JX-10 with single patches). The JX-10 also has a slightly different amplifier section as well as different electronic components which further distinguish its sound from its predecessor, the JX-8P.
