What is the "HAWK-832" kit? *** The HAWK-832 should be available in late 2024. ***

The HAWK-832 is an electronic hardware and software upgrade kit (currently being developed) for the Korg Poly-800 MK1 (PS-800), and the EX-800 and the MK2 models. The HAWK-832 kit will give those three music synthesizers amazing new sound making capabilites along with advanced MIDI controls and, many new user performance features. For details on the many features, see the 'Main Features' section below. These pages also provide details of the previous upgrade kits known as the HAWK-800 and AtomaHawk. The HAWK-800 (and its corresponding AtomaHawk kit) are no longer being sold but all of the support pages are found here below. Meanwhile, the HAWK-832 kit will be a superior upgrade over the HAWK-800 when it becomes available (hopefully very soon!).

HAWK-832 Development Road Map...

The original HAWK-800 kit was developed and offered for sale in 2007. Over 5,000 kits were sold between 2007 and 2021. Then Covid came along and disrupted the supply of flash memory chips that are used in the HAWK-800 kit. This disruption continues even today! The disruption prompted me (Mike) to revisit the idea of creating a brand new kit. The chip supply problem is one problem but the limited computing resources of the HAWK-800 also suggested a new higher performance kit.

Because, the HAWK-800 only has 24K of program memory, 32K of patch storage and 8K of static RAM. It also uses the original Intel 80C85 CPU that runs at just 6Mhz. Despite that, those who bought and installed the HAWK-800 kit well know that the new and improved features are fantastic! But the HAWK-800 kit has reached a point where there is no more memory capacity available to improve features or add new ones. So an upgrade kit using an STM32 (a 32 bit ARM CPU) based kit would come with 192K of program memory, 64K of patch storage and 64K of static RAM. Most importantly, the STM32 CPU runs at a whopping 72Mhz.

So, a new kit is born! The HAWK-832, which uses the STM32F373CC. The dramatic increase in CPU storage capacity and speed will provide a large amount of room for improving the performance of existing features and for implementing new ones.

Also, the HAWK-832 kit should be easier to install when compared to the older HAWK-800. The HAWK-832 kit will require removal of the 80C85 CPU and replacing it with a 40 pin socket into which the HAWK-832 module will be inserted. This makes installation of the kit easier and less risky too.

For those that adore the AtomaHawk, we *might* produce a version 2 that will operate with the HAWK-832. But, a plan is being hatched to develop a new tone generator that will replace the MSM5232. The new TG will precisely emulate the original TG (the MSM5232). So the lovely chiptune square wave sound will be retained and we will add new waveforms. It's not yet certain how many new waveforms will be available in the new TG but, at a minimum, it should have sine, sawtooth, and pwm. And the DCO's will all be independently clocked! Independent clocking of the TG oscillators will give the synth voices warmth and depth. Also, the original paraphonic filter (NJM2069) will be retained as well. So the single filter will continue to provide rich, vibrant sounds along with the original DCO's or the new DCO's. We might even be able to squeeze in some new TG filters to complement the original NJM4069D.

For now, the HAWK-832 will be a dramatic improvement over the HAWK-800 which itself was a huge boost for the Poly-800.

HAWK-800 Technical Support

What is the "AtomaHawk" kit?

The AtomaHawk kit is another hardware upgrade kit for the Poly-800 (that was available for all three models) that takes control over the popular hacker modifications known as the Moog Slayer (extreme resonance including self oscillation), FM-800 (DCO modulation of VCF) and 12/24db per octave filter slope. The AtomaHawk kit was controlled by the HAWK-800 (no longer available) hardware kits so you must already have the HAWK-800 installed before you can install the AtomaHawk (no longer available). With both the HAWK-800 and AtomaHawk kits installed you have a revolutionized synthesizer with many new sound abilities.

Where is the "HawkyStick" kit? *** The HawkyStick kit is NOT currently available. ***

The HawkyStick kit is another hardware upgrade kit for the Poly-800 (also available for the Mk2) that is a complete replacement of the original joystick. This kit is being redesigned so that the physical installation is dramatically improved. I don't know yet when the new kit will be available.
