You mean the JX-8P or the JX-10? Cuz "everyone" says the JX-10 sounds different, that the JX-10 chorus is different from the 8P's, that they prefer the sound of the JX-8p to that of the JX-10, and that JX-10 really isn't 2 stacked JX-8Ps because there are architectural differences, particularly:Morphoice wrote: Thu Jul 16, 2026 7:18 pm And just about any patch you dial in should sound exactly as it does on the hardware.
The JX synthesizers employ a four-pole lowpass filter, which rolls high frequencies off at a rate of 24dB per octave. There is a slight difference between the maximum resonance amount setting in the JX-8P and the JX-10. When pushed to its upper limit, the filter in the JX-10 will oscillate producing a sine wave, but this effect is not possible on the JX-8P.
