JX-3P

 ROLAND JX-3P




I bought mine back when they were still a hot new keyboard to have. In the intervening years it has been damaged and repaired many times. There was some damage even now has not been undone. A male cat urinated on the keyboard and the acid in the urine ate away at the circuit board and the sensor for the keys. As a result there are five keys in the lower register that I cannot play locally. I have noticed  recently people are interested in the old analogue sounds, even with their imperfection, I know I always have.YES it is old. The date on the back of my manual is Mar 84.

I cannot guarantee the accuracy of this chart. I have filled it in as best as I could.

NOTES FOR NON DOCUMENTED FEATURES

These notes have been taken from somewhere else but I forget where.

HIDDEN BANK ACCESS

16 extra slots for user tones. I'm not 100% sure but this "feature" seems to use the sequencer memory. If you change one it seems to change the other. This can be interesting as long as you remember that editing your sequencer will affect this tone bank and vice versa.

    Hit TAPE MEMORY
    Hit TONE SELECTOR 5 and hold it
    While still holding key 5 hit TAPE MEMORY again

    To reset hit TAPE MEMORY twice

To save or load the hidden bank enter the hidden bank mode and load or save normally.
 
 

POLY II MODE

This differs from POLY I mode in that only the last note or notes played receive their natural release length, and is much more suitable where certain types of staccato playing to slow fade effects are required. (sorry about the English, I didn't write it.)

For use with the original 32 presets.

  Hit TAPE MEMORY
    Hit TONE SELECTOR 3 and hold
    While still holding key 3 hit TAPE MEMORY again

For use with the hidden bank.

  Hit TAPE MEMORY
    Hit TONE SELECTOR 6 and hold
    While still holding key 3 hit TAPE MEMORY again
 
 

SEQUENCER LIGHTS

The LED's light up as the sequences play - cute.

  Hit and hold REST button
    While holding REST hit START/STOP
 
 

MANUAL SEQUENCER PLAY

It's cheap but it works.

    While in overdub mode hit TAPE MEMORY to advance the sequencer manually.
 
 

MODULATING WITH NOISE



This is a really cool effect!

    When editing, hit GROUP B and TONE SELECTOR 10
    Press GROUP D button

HOW DO I GET IT OUT OF OMNI MODE?



1) The easiest way (if you have a sequencer or device that will send it) is to send a POLY mode command (MIDI Cc 127 with any value). To turn OMNI back on send a OMNI command (MIDI Cc 125 with any value).

2) connect MIDI IN to MIDI OUT while the JX-3P is off and turn it on.

3) connect MIDI IN to MIDI OUT and play more than 6 voices at the same time.

The following were part of an EPROM update - if they work you've got them !
I can't vouch for these I can only assume I have an older version.
 

DYNAMICS WHEN PLAYED FROM A TOUCH SENSITIVE KEYBOARD

    With the JX-3P off, hit and hold TONE SELECTOR 5
    Turn power on
    Keyboard will cease to function (local control off)
    Synth will now act as a slave touch sensitive keyboard

alternately

    Hit TAPE MEMORY
    Press and hold TONE SELECTOR 7
    While holding key 7 press TAPE MEMORY again
 
 

MIDI CHANNEL 3 AND DYNAMICS

    Turn on dynamics mode via either method above
    Press TAPE MEMORY
    Now your keyboard will respond to MIDI channel 3 but Local control will be off
