An update on variable LFO rate

An update on variable LFO rate

2008-09-08 by korgpolyex800

OK,

I may have mentioned this before but... I have been playing with the
LFO rate variation over the weekend and it is very nice indeed.

In short, the two SLFO's (LFO3 and 4) can be routed to either LFO1 or
LFO2 to vary their rate. And you do this with a depth value of 00-15.
Zero means no rate variation and 15 means full. It's very nice to hear
the rate of the LFO's modulate against the SLFO's.

The waveform from the SLFO applied to the rate of the LFO is the SLFO
triangle waveform. I am looking into using the other waveforms. I am
thinking that square PWM would be really cool when modulating the
rates of the LFO's.

"Reads" good! Sounds? Videos? I know, I know, I'm greedy... but, marketing-wise, a video is worth a zillion words...

OK, I promise that I will do a quick video this evening of LFO rate variation.

Last night, I was having so much fun making sounds that I ended up not doing any video.

I'll fix that tonight.

Mike.

New youtube video of the LFO's with rate modulation

2008-09-09 by korgpolyex800

OK,

I've uploaded a five minute video that shows the kinds of sounds you
can now get out of the Poly-800 when upgraded with the HAWK-800 kit.

This little video show cases the rate modulation of the LFO's as well
as send MG into bend (which varies the master oscillator by almost an
octave) instead of just the DCO modulation (which only modulates
across a semitone each way). This gives us the ability to create real
siren effects. Especially with the use of PWM square, sine, saw and
triangle waves. And don't forget the random sample and hold.

Enjoy!

Mike.

OK, after spending quite a few hours pulling my hair out I finally got
the LFO rate modulation working with different waveforms. Now you can
modulate the rate of both LFO's from the SLFO's and apply different
waveforms. Triangle, sawtooth, sine, square with PWM and random are
all available.

Now, onto FM-800 and resonance modulation and EG follow.

Moog Slayer and FM-800 in the HAWK-800 AtomaHawk-800 prototype

2008-09-15 by korgpolyex800

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.

Mike
