I will update the owners manual to discuss this.

Thanks to Fran for providing the answer before I could !

When you first install the HAWK-800, the flash memory that is used for the patch storage contains alot of invalid data. So the HAWK-800 automatically validates all of the data and when it finds parameter values that are outside of the normal range it resets the value to half the maximum. As Fran points out, parameter 87 is the EG3 retriggering parameter. In most cases, this parameter will be off (zero). And also, every patch can now be stored with the Poly mode as either Poly, Hold, Chord or Slide. Parameter 88 sets that.

So I recommend that you download either an EX-800 or MK2 sysex bulk dump and set all of your patches up.

Mike.

Hello

I recently installed the Hawk 800 into my Poly 800 MK1. Everything went as planned per the directions up to the flashing process. The flash went as planned but when I hit prog/para after I end up in 11 H instead of 11 P.

There is also a constant mid/high sweeping sound regardless of keys being pressed. When I use the mood slayer cutoff to about 50% I can make it mostly become silent. The sweeping alters when buttons that transmit midi signals are pressed (the poly/chord/hold buttons, moving the sequencer speed slider, etc). I have tried reflashing it multiple times including with the beta software version. Do you think I may have damaged the circuits? Or could it be a loose connection from removing the board? Also if someone could send me a MK1 sysex patch dump I'd greatly appreciate it so I can test if it will load up sounds.

Thanks a lot,
Tom
