Also, if you like the way that the mod sharpens the attack, but you don't like how buzzy it now sounds, you can eliminate Korg's own modification to boost the highest treble frequencies...

But this means that I can now turn down the filter cutoff knob on my synth. With the stock Polysix, I was always wanting to open up the filter more, but I couldn't because the knob was already maxed out. Now I've got the added flexibility. My preference.

If you free-hand play the "before" case and the "after" case, the two samples end up sounding too different...the listener hears the difference in performance more than the difference in timbre. So, I was forced to use my (hacked) arpeggiator...hence you get the highly repetitive demo. If I ever put a MIDI jack on my synth, I suppose that I could use a sequencer from my PC...but what fun would that be!?!
