Ryszard,
If you have a GK installed on a Strat copy and a VG-88 you already HAVE pitch to MIDI and you COULD control the JV-1010 via the VG-88 (unless I just misread the VG-88 users manual)??
I “control” a whole RACK of synths (plus three keyboards & and PC SOFT synths) via GK enable guitars through/via my GR-50, which I now use only as a pitch to midi box. The internal GR-50 D-110-like sounds, while quaint, are not my first, second, or even third “go to’s” anymore (but once in a while – they are fun nonetheless).
As far a HW – a quick search a for a NEW GK3 via Musicians Friend is $219 (a used one would be cheaper even a older GK2a which is+ what I have on one guitar) but now we need a interface
Before we go on: I will assume whomever is interested in this topic, as I said before, can already PLAY a guitar and has at least ONE guitar they own. It doesn’t not have to be a electric guitar, so even inexpensive acoustic 6-stirng “starter” guitar will work. Although it must have steel strings – nylon string will not work.
Then a GI-10 for $129

http://www.ebay.com/itm/Roland-GR-33-Gui...=item2a20f46c90or as MAC mentioned earlier a GR-1 for BIN of $185
http://www.ebay.com/itm/ROLAND-GR1-GUITA...=item1c29a7914bThe end result is a REAL guitar (so all the nuance and control of your fingers and picking on real strings and frets) and Pitch to MIDI and MIDI control over other sounds in other modules and the PC for WELL under (or near) $400 and I wasn’t trying to get the cheapest solution.
as far as Alan Holdsworth well ... he's in a whole other league. Even if we/I were outfitted with HIS equipment - he could probably play circles around US (me for sure) even if all he had was the EXISITING $140 YRG. He has been playing synth guitar(s) for so long that every type, trick, nuance, method, and shortcoming work-around he already has built into his muscle memory.
