Hi everyone!

I've been pretty quiet on this forum for a while now, seemingly not
much new to add, but it's because I've been, amongst many things,
working on some mods that will blow you all away!! I'm in the process
of completing them and writing up a how-to guide for each one as I
go, and I'll upload them here on this site.

Although there are other great Casio forums around, such as the
mighty Casiologue forum, I've always felt a fondness and 1st loyalty
for this group, being my first circuitbending forum I ever joined,
and have gained so many great mods and advice from this site,
especially from plutoniq9 and his great memory expansion mod! So I
intend to release my mods here first!!

Here is what's in store when they are completed and road-tested:


*** Instrument Slow Attack/Decay mod (already completed and running):
***

- This mod will allow you to change the attack and decay of all of
the SK instrument sounds, including samples. You will be especially
able to turn the fast attack/decay sounds into slower attack/decay
rates, for things like string pad sounds, using a multi selector
switch. A simple mod, inexpensive and great sounding!


*** Drum Rhythm Sounds VCF Filter (already completed and running): ***

- This is a VCF filter for the drum rhythm sounds, with manual
frequency and resonance controls, so you can do all those great
sweeping filter sounds, like starting from a completely muffled, dead
thud, opening up to midrange bite, through to sparkly trebles!

It also has a CV input for control from a keyboard controller or
sequencer and a MIDI-CV unit like a Kenton CV box - you can control
the filter frequency remotely and sequence it!!

You can also trigger the filter off an instrument sound envelope. For
example, selecting a fast attack, slow decaying instrument sound,
such as the guitar preset will cause the drum rhythm sounds to start
out bright and trebly, and gradually decay into a muffled, dead thud
sound. Choose a slow attack instrument, like the violin - the
opposite happens. Choosing the sample envelopes will give even more
variety.
This mod benefits even greater if you do Plutoniq's "Drums Direct
Output mod" (in the FILES section on this site) - it means that you
can have the instrument volume turned right down to zero, and have
the drum and filter sound still playing without an instrument note
playing over the top of it.

**********************************

AND NOW, INTRODUCING THE BIG ONE - A FULL BLOWN, POLYPHONIC 4-VOICE
VCF FILTER FOR THE INSTRUMENT AND SAMPLE SOUNDS!! (partially
completed and running):

This mod will blow you all away!!!!!!!!!!!!
It truly turns the humble SK5/8 into an analog monster machine!

This true polyphonic 4-voice VCF filter has frequency and resonance
controls, CV input, and attack/decay selection!

You can choose manual control cutoff frequency, or select "envelope"
control, where the filter follows the attack/decay envelope of the
sound selected.

For example, selecting a sound like the violin preset will give
a "wwhhaahwww" type filter sound. Choose a fast attack/slow delay
sound like piano or guitar will give an "aaaoowww" type sound!!
Using the sample envelopes will give even more variety.

You can also vary the filter attack/decay rates - this has
the "Instrument Slow Attack/Decay mod" already incorporated into it!


***********************************************

Well, I hope that has given you all something to dream about! I'm
going to also upload audio samples, to give you an idea of how each
mod sounds, and what it's capable of. It should take me about 2 or 3
weeks to finalise all of the guides and upload them, so keep posted
and watch this space!!!!

Cheers, Graham
