Howdy y'all;
The polivox is basically a very high frequency vco
running at around 2 Mhz (more or less) tied via a PLL
(phase loocked loop ) to a Top Octave Generator that
divides down the high frequency vco signal into a 'top
octave' -a full octave including semitones- using
whole integer binary dividers inside... the keyboard
as I recall allows you to select the 'polytonic '
notes 'phase looped' to say an external synthesizer's
vco output.... hope you get the idea.
Ah... Mostek used to manufacture these top ctave
generator chips MK50246 or something like this and
radio shack use to sell them... I do have a couple of
these chips somewhere in my garage.. no telling when I
could find them ...:(
bye now...
