> I have a VZ-10M but haven't been doing much with it because I am the
> engineer that produced the HAWK-800 kit for the Korg Poly-800.

> Let me give you a bit of an idea how difficult the task was.

> I started the project late 2006. I began by determining if it was
> feasible to change the hardware to use a larger amount of memory if it
> was supplied to owners in some sort of a kit. I then moved on to
> beginning to disassemble/reverse engineer the little 8K ROM where the
> Poly-800 software resides. Although the Poly-800 is analog, it is
> still mostly software controlled. About March 2007 I realized the idea
> was very possible and I developed a prototype board. I then began the
> tedious task of reverse engineering all of the 8K of software. Toward
> the end of 2007 I had added quite a few new MIDI features including
> SYSEX patch send and receive as well as adding MIDI controllers for
> VCF cutoff, resonance etc. At that point I had enough interest from
> Poly owners that I developed the printed circuit board, the
> construction and installation instructions and MIDI implementation

> trying to develop a third kit that will fit into the Poly-800 MK2.
