Oh yes it's all possible, You can create your own sounds, well sort of. Basically you start with a waveform. You can use up to four waveforms per patch. There are (I think) three banks of waveforms in the JV1010. The Preset A, Preset B and the waveforsm on the delivered Session card.
You can mix em up any way you want applying various parameters to each waveform.
And you can also change that Preset E bank patch youlike, but you have to store you edited version in the User bank.
The JV1010 ships with a version of SoundDiver for XP/JV synths. I'm using the same software for my XP-80. I don't know how to get a copy though.
