Hi Everybody!!
Well, here it is - the magnificent
PHAT PHILTER BANK mod!
This mod truly turns the humble SK5/8 into an analog monster machine!
It is also suitable for other SK keyboards, such as the SK1, SK10/100/200 etc, though the hooking up connections may be slightly different for them.
This true polyphonic 4-voice VCF filter has frequency and resonance controls, and CV input.
You can choose manual control cutoff frequency, or select "envelope" control, where the filter follows the attack/decay envelope of the sound selected. You can also select LFO control of the filter if you have the LFO mod installed.
For example, selecting a preset sound like the violin preset will give a "wwhhaahwww" type filter sound, if set to “Envelope” mode. 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.
The fully illustrated, step-by step guide is in the FILES section onthe Yahoo groups Casio SK site:

I will put some mp3's up there shortly, to give examples of the amazing sounds this thing produces.
Cheers, Graham
