I updated my JP-X to v.2.0 this week.
I am really not sure if this is part of the design of the JP-X, but on some sounds - if I move the mod-wheel up to full and back down again (whilst holding down a chord) - the volume of the preset disappears (ie. no sound!) when the mod-wheel reaches home again. In order to get the preset to sound again I have to re-select the preset!
I have never experienced this ever before on any synth in 30+ years!, or witnessed it in any of the You Tube demonstrations I have watched to date. Maybe this feature (not that I like it at all!) is 'deliberate' on this particular synth? Also, I have not read any complaints elsewhere regarding this scenario so either:
- it has been designed this way,
- or else, there may be a fault with mine?
