Don't even consider the JV1010 unless you only want to select and playback patches- It is hardly editable from the front panel- you require a computer to edit it (with the supplied soundiver software). It only has a single pair of stereo outs (unacceptable for a multi-timbral synthe such as this)
Check it out if you don't mind using it with a computer. Otherwise don't bother! Yes it is alot cheaper but at a price.
