Octave Switch; Chain Mode - Roland JX-03 User Manual

Octave Switch

The keys available for programming sequences, and the one octave ribbon control input method is only 12 notes at a
time. Further, with a K-25M keyboard attached the keys are still limited to two octaves. Sometimes in performance, or
composition is it desirable to shift the octave of the keyboard up or down to access other notes which may not be
readily available with the current keyboard. The available range is -4 to +5.
To shift the octave of the keyboard and ribbon control input strip in one octave steps:
1. Hold MANUAL and press Preset 1
2. Preset 4 - Preset 13
The default setting of +/- 0 is the 8 key

Chain Mode

Although the JX-03 is four-note polyphonic, you can increase the polyphony by using a MIDI cable to connect two of
more JX-03 modules together and turning chain mode on.
When using two JX-03 units together it is recommended to match their respective patch settings by using the backup
and restore procedure. This way all the patches in both modules will be the same.
This allows for 8 note polyphonic performance from two JX-03 modules. When in this mode, and the same module is
being used, all control of both modules will be handled by the first module in the chain. Thus, calling up patch A11 will
automatically call up the same patch on the second module, and the results will be an 8 note polyphonic version of
patch A11.
While increased polyphony works between the JX-03 and other Roland Boutique modules (ex: JU-06 or JP-08) the
results will be slightly different. Control of the two synths will remain relative. Only the additional notes called for will
be accessed by the second unit. While this is different from having all the same patch with 8 possible notes to play, it
can also produce very interesting layers and at times unpredictable results. It's also possible to connect other
synthesizers to the MIDI OUT port and achieve interesting results using all sorts of sound sources for the notes
beyond the first 4 played.
