Welcome to the development pages for the HAWK-800. The HAWK-800 is a hardware/software upgrade kit for the Korg Poly-800 line of synthesizers. The HAWK-800 can be installed in the original Korg Poly-800 as well as the MK2 and the EX-800 synth module.

The HAWK-800 software provides a dramatically improved and expanded MIDI implementation as well as many new sound and user control features. The HAWK-800 also allows total control over three of the most common hardware modifications; the "Moog Slayer", the "FM-800" and the 12/24db filter slope mod's.

The sourceforge HAWK-800 project is where I am slowly making all of the rewritten assembler available along with all of the documentation, owner manuals, patches etc. The hope is that the HAWK-800 may be further developed by a team of passionate and dedicated Poly owners other than myself.

The HAWK-800 sourcforge project is also going to be the place where all bugs will be tracked, help pages written and feature requests lodged.
