P2 85 - Bend Depth; P2 86 - Portamento Rate; P2 88 - Poly Mode; General Hints And Tips - Wantegrity HAWK-800 Owner's Manual

Sets the depth of the tremolo. When you wish to apply the largest tremolo it is best to set the DCO2 volume (parameter
27) to 17 (the volume midpoint). This allows the maximum amount of tremolo depth (15) to be applied.
P2 85 – Bend Depth
00-63 – 00=bend off, 01-63 apply joystick bend
Selects the amount of bend depth that the joystick will apply to pitch bend, DCO and VCF modulation.
P2 86 – Portamento Rate
00-63 – 00=fast portamento through to 63=extremely slow portamento
Selects the portamento slide rate between notes. Setting this parameter to zero selects glissando. Setting the portamento
to any higher value slows the portamento slide rate down.
P2 88 – Poly Mode
0-3 - 0=Poly
1=Chord
2=Hold
3=Portamento
Selects the key assign mode for the patch. By setting this parameter (and saving it) you can preselect the key assign mode
for each patch. When you select any patch , the Poly-800 or EX-800 will automatically change to the key assign mode set
by this parameter. If the sequencer is running when you change patches, the key assign mode set by this parameter will be
ignored and the key assign mode will remain in Poly mode.

General Hints and Tips

Initializing Patch Flash Memory

The first time you install the HAWK-800 kit into a Poly-800 the flash memory used to store patches will have random data
within it. When the HAWK-800 is powered on it immediately carries out a patch data validation check. Any patch
parameter that is found to contain data that is outside of the limits for that parameter will be reset to be exactly half of
the allowed range for that parameter. This means that the first time you power on the HAWK-800, you will find that your
patches behave strangely due to two parameters that will be set to mid values. Most other parameters are OK with mid
range values but parameter P2 88 sets the poly mode and at half it will be set to 2 which corresponds with "Hold" mode.
So you will generally set parameter P2 88 to Poly mode (1). That will get your new patches sounding better faster. You
could also send an EX-800 or MK2 sysex bulk data message to get your patches working faster too.

Ribbon Header Cable Troubles

The HAWK-800 kit was shipped out to customers with two ribbons cables that plug into IC sockets. We have received a
couple of reports where a HAWK-800 has stopped working because the ribbon cables had popped out of the IC socket.
This usually occurred after a HAWK-800 had gone "on the road" or had been dropped hard etc. To avoid this problem, we
recommend using four plastic twist ties. Use plastic coated twist ties and make sure that none of the metal wire is
exposed. Carefully thread each twist tie under one of the IC sockets. Then, plug in the ribbon cable header plugs and twist
the twist ties over the header plugs so that the plugs are much less likely to dislodge from their sockets. If the twist ties
you use are too short to twist over the header plugs then either obtain longer twist ties or use eight twist ties so that you
can twist them together to form a longer tie.
