Roland Jx-10 Owner's Manual page 66

4.02
•
Bug fix: when converting Roland tones into 'pwm' tones, the LFO waveform could be wrong. Specifically,
random and square are swapped.
4.03
•
Bug fix: Editing both tones simultaneously with MIDI CC was done incorrectly (3.x not affected).
4.04
•
Bug fix (JX10 only) : patch parameter "MIDI key mode", when mode is UPPER or LOWER, is considered
as LAYER.
4.05
•
Added support for GU280 display (see 3.11 above for details).
4.06
•
GU280 display is turned off by default after upgrading. You must go to the menu to turn it on, even if the
menu says it's already on (reason: this confused people who don't have the GU280).
4.07
•
The Roland PULS (now used to create real PWM) is back! If you set PWM WIDTH to 00, the old Roland
method of generating a pulse (by overdriving the ramp generator) is used, instead of the pwm daughter
board. The change is IMHO not audible (or very subtle). But, this allows to install 4.07 without the PWM
daughter boards (you still have to update the 8031 cpu to a DS80C320 and use 4.01 sound board
eproms).
4.08
•
Arpeggiator support for MKS70
•
Unison and Mono key assign modes are now supported in A-WHOLE an B-WHOLE mode.
4.09
•
Bug fix: GU280 display bug fixed (See 3.11 / 3.12 for explanation).
