Korg Poly800/EX800 Users

Well, it's been another big weekend for the HAWK-800.

As you all know, I have a prototype Moog Slayer, FM-800 and 12/24 db
filter switch mod in place on my Poly 800 along with the HAWK-800
controlling them.

This weekend, I completed setting up extended parameters for EG3
control of Moog Slayer and FM-800. Moog Slayer is really just extreme
resonance. My Moog Slayer mod uses a switched resistor to increase the
resonance. And the resonance parameter has now been made to range from
00 - 99 (instead of the original 0-15). EG3 can be applied to either
resonance or FM-800 using two independent extended parameters. Depth
is set in the range 0-15 the same as EG INT parameter 45 influences
VCF cutoff. There are also two parameters that allow inversion of EG
influence over either Resonance or FM-800.

That basically completes the two mod's except for using LFO's to
modulate them. I will be working on that over the coming weeks.

I also have to finish the code to modulate the amplitude of the LFO's
1 and 2 using the signal from SLFO3 or SLFO4. But the main challenges
have been solved and I don't foresee this taking too long to do
either. The great thing about the SLFO's is that I can use time slots
to handle them, which means I won't be taxing the CPU because each
modulator can be handled one at a time.

There's light at the end of the tunnel.
