I wonder if I can connect GK-3 directly to Logic or Cubase. will the application see the GK-3 as a midi device?
If not, are there any simpler converters that I can use as I'm interested in utilizing the sounds in my computer bank rather than synthesizers such as GR-20.
Sounds as if you need a GI-20..

The GK-3 is purely a pick-up, a very clever one admittedly.
To convert the signals into MIDI information, or for direct computer connection via USB then you will need a GI-20 at the very least. This is only a converter, it contains no sounds.
I will point out there are only USB drivers currently available for:
Mac up to OS X
Windows 98/ME, 2000/XP, and Vista - 32 bits only.
No 64 bit drivers, and no Win 7 drivers - yet at least. It a sore point that one..
A bit more expensive granted, but a VG99 will do the same thing (and all the other amazing stuff it does anyway) and has windows drivers for Vista 32&64;bits and Windows 7 32 & 64 bit versions. The £400 it would cost you to go for a GI20 may be better put towards a VG99. Think of it as buying a GI20 and getting a VG99 half price!
All the GK3 will do is provide an analog signal from each string individualy. This allows the pitch to midi device (i.e Roland GR-20, GI-20, VG-99) to distingush each strings note.
The GK3 is a hexaphonic guitar pickup.
