"This unit has both the HAWK-800 and the AtomaHawk upgrades installed, as detailed here:

The upgrades/mods add the following features:

NEW SOUND FEATURES:
1) Portamento mono mode with slide rate parameter stored per patch.
2) Tremolo - apply either LFO1 or LFO2 to the volume of either of the DCO's volume with control over Tremolo depth for each DCO.
3) The single LFO is now two (LFO1 and LFO2) and two more super LFO's (SLFO3 and SLFO4) have been implemented.
4) All four LFO's have triangle, sawtooth, sine, square PWM and random sample and hold waveforms. All waveforms can also be inverted.
5) All four LFO's have free running modes.
6) LFO1 and LFO2 delay type select - allows the LFO's to cycle at note on and then stop cycling when the delay timer expires. This allows the reversal of its original behavior where the LFO delay timer must expire before the LFO begins to cycle.
7) LFO2 sync to MIDI clock.
8) EG3 retriggering sync by MIDI clock.
9) Note triggered sequencer transpose - You can now select a global parameter that will set up the keyboard to transpose the playing sequence. You can also set the mode to allow MIDI to transpose the sequencer too.
10) Resonance can now be modulated by LFO's and the envelope generator.
11) The LFO1 frequency can be modulated by SLFO3.
12) The LFO2 frequency can be modulated by SLFO4.
13) Random sample and hold waveform clocked by the on board seq. or MIDI clock.
14) Random sample and hold waveform clocked by sequencer repeat.
15) DCO harmonics can now be modulated by any of the four LFO's.

NEW MIDI FEATURES:

1) MIDI controllers (special and NRPN) for all original and extended parameters.
2) MIDI standard controllers implemented for LFO1 rate, VCF cutoff and resonance depth.
3) MIDI controllers for setting Poly, Hold, Chord and Portamento modes.
4) MIDI sustain controller send and receive.
5) MIDI SYSEX single patch dump send and receive.
6) MIDI SYSEX bulk patch send and receive.
7) MIDI EX-800 SYSEX dump receive (sequencer and patches).
8) MIDI Poly-800 MK2 SYSEX patch dump receive (patches only).
9) MIDI user initiated SYSEX HAWK-800 bulk dump all patches.
10) Selectable Omni On, Off or Auto on power up.
11) Keyboard MIDI TX channel selection (1-16 or no MIDI TX).
12) Joystick MIDI TX channel selection (1-16 or no MIDI TX).
13) MIDI soft thru of all messages.
14) Sequencer MIDI time code send on/off.
15) Chord mode synchronization SYSEX send - if cascade sync mode is selected then pressing the chord key will send a SYSEX message to set up the chord progression table. This allows a slave unit such as an EX-800 to operate in chord mode with the same chord structure as the master unit.
16) MIDI patch bank selection (1 of 4).
17) MIDI note on velocity sensitivity where VCF and envelope generator parameters can be influenced by incoming MIDI note velocity data.

NEW USER FEATURES:

1) All notes off panic button (with MIDI TX too).
2) Local keyboard control on/off.
3) Local joystick control on/off.
4) Extended playing range on/off (increases the playing range by two octaves while ignoring the parameters 11 and 21).
5) Cascade mode (for when you have two Poly's or a Poly and an EX800. One unit plays odd notes and the other plays evens).
6) Cascade sync mode (the master unit sends SYSEX patch dumps to the slave as well as setting the Poly mode and patch number. This ensures that your slave unit plays exactly the same sounds as the master).
7) Poly mode is stored and recalled with patches.
8) Bend depth stored per patch.
9) You can send the global parameters from the Poly 800 to another Poly-800 or EX800.
10) A global parameter is now available that allows setting the keyboard MIDI note velocity.
11) Local sequencer control on/off so that you can send the Poly 800 sequence to another synth via MIDI.
12) A global parameter now allows keyboard MIDI transmit octave shift up or down 3 octaves.
13) You can cancel out of a patch write by pressing the write button (instead of reaching around the back and fiddling around for the write enable switch).
14) All user patches, globals and sequencer data are stored directly in flash memory so that you no longer need ANY backup battery.
15) Sustain pedal operation. The original "step up" jack now also operates as a sustain pedal with patch control over decay and release times as well as sustain hold point.
16) Joystick parameter editing and patch section. You can now change the operation of the joystick to edit patches and select patches.
17) The Up/Down data keys also operate as patch up/down selectors when in Program mode.
18) Four banks of 64 patches (for all kits shipped from June 2009 onward) giving the HAWK-800 256 patch storage in flash memory (no backup batteries are required).
The install is clean and was professionally done without any additional drilling etc (one board was hot glued to the chassis). Works great, but sold as is, no returns.
Does NOT include power supply - uses a standard, 9V negative center supply."
