Roland JX-10
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.
Like most synthesizers of the time, the JX-10 is programmed by selecting the desired parameter through a keypad and editing that parameter using a data wheel Roland dubbed the "Alpha-Dial". Like the JX-8P, this editing technique can be bypassed by connecting a PG-800 device to the programmer port located on the back of the keyboard synthesizer, or on the front of the rack-mounted version. Alternatively the JX-10 and MKS-70 can be programmed over MIDI using a controller device such as the KiwiTechnics Patch Editor (a firmware update is required on the JX-10).
The JX-10 and MKS-70's factory presets were created by Eric Persing and Dan DeSousa.
The JX-10 combines two completely separate 6-voice Tone Modules (A-Upper and B-Lower) which allow it to function as a single 12-voice synthesizer or as two 6-voice synths capable of layering or splitting two different Tones simultaneously. There are six playing modes:
The JX-10 has space for 64 patches in its internal memory, each of which can be composed with one (12-voice) or two tones (rendering the synth 6-voice polyphonic). These tones can be selected individually, combined together, or split. Of the 100 available tones, 50 of them can be edited and saved to memory; the other 50 are factory patches. The JX-10's memory can also be expanded by plugging in a M-16C, M-32C (very rare, originally only available on the Japanese market) or M-64C memory cartridge. If a cartridge is inserted, the JX-10's built in sketchbook sequencer can be used (it can only be used if a cartridge is present). The JX-10 / MKS-70 can also read and write tone data for the JX-8P this way (which in turn can only use the M-16C). The M-64C can store 64 patches and 100 tones; the M-16C can store 32 tones only (no patches).
The MIDI implementation on the JX-10 is somewhat faulty and lacks common features. Most importantly it cannot send or receive Tone or Patches by MIDI SysEx. The MKS-70 (rack version of the JX-10) does however send and receive tones and patches over SysEx because it has different firmware in EPROM. If the firmware in the JX-10 is updated, then it will support SysEx.
The JX-10 transmits MIDI Control Change 123 (all notes off) instead of "normal" MIDI Note-Off messages every time a key is released (the JX-8P does this as well). This can be filtered out by editing CC 123 in the sequencer if it creates any problems; normally it does not.
Like the JX-8P, the JX-10 also has a 2U rack-mounted counterpart called the MKS-70 which was available 1986–1989. It is basically the same as the JX-10, except that the MKS-70's tones can be edited through MIDI using SysEx (this can be rectified on the JX-10, see below).
