Keyboard = 76 keys. Memory: Patch memories (two tones with split/layer, volume, aftertouch sensativities, Midi channels/split point, etc.) Internal Patches: 64 Cartridges (way too expensive [45$ or so]) 64 Tones (what you think of as sounds 2 Digitally Controlled Oscillators, one high pass filter, one fully envelopeable low-pass filter with resonance (it is a VCF!) VCA with gate and env modes, two ADSR envelopes (assignable to pitch, VCA, VCF, crossfading in the mixer section.) one LFO with sine, square and RANDOM waves, assignable to pitch and/or filter, assorted mod routings for velocity. Chorus (off,1,2), coarse and fine tuning, etc.o Internal tones:50 preset, 50 user. Cartridge 50 user. The JX also has a primative reecord/playback sequencer if you want to waste a cartridge. As far as sliders are concerned, forget it. That's why I wanted a PG-800. It has all the sliders you could ever want on it. If you can deal with just aftertouch and volume real time control or spin the edit wheel while on a particular parameter, then youy don't need the programmer. Chase mode: Kind of a delay where you can set a delay between the upper and lower tone in a patch. You can set it to play U-L, U-L-U, or U-L-L and at what speed and for how long. Kinda fun! Real time controls: two assignable (master volume, tone balance, portamento time, Upper or Lower midi volume) sliders. These can be "expression" type pedals, but then the front panel sliders are turned off when you plug in a pedal. One switch-type assignable pedal (patch shift, portamento on/off, chase play on/off, upper or lower hold (sustain) on/off.) Tunable from 435 Hz to 446 Hz. (A = "440") Local on/off; transmits and recieves controllers 1,5,7,64,65. transmits and recieves program change messages for the tones or the patches. Transmits and recognizes "all notes OFF" Pitch Bender only does 2/3/4/7 semitones on the internal voices but will send the right data for any external modules (depending on how much you tell them to bend.)l think the sounds in this board are great, but you might want to know that I am here at UCSD, and being a starving college student, I don't really have the funds to ship this thing out. As far as the MKS-80, I don't really know what to tell you. I know that the JX-10 is (was) the flagship of the JX line (3P, 8P, and 10) and the MKS-70 is just the rackmount version (both are "subtitled" Super JX.) The MKS-80 is (I think) the rackmount (I don't know if there was a corresponding keyboard) "Super JUPITER." The architecture is slightly more complex (I think it has another DCO, another filter and one or two more envelope generators.) Seein g as you are looking for a good KEYBOARD, I don't know if that would really serve your purposes. If you need more information, tell me. (By the way, what's your land address?) Patrick T. Rost P.S. I have the manual. Sorry, I lost your address Brian!
