The JV-1010 is compatible with the other Super-JV synthesizers.
You can find some Sysex listings on the Li'l Chips web site at http://www.lilchips.com
There is also documentation in the MIDI Implementation area of the 1010 manuals (it may be on the CD if I recall).
The EFX are difficult (but not impossible) to control via sysex due to their complexity.
