Just curious.  Until recently I was totally unaware that casio actually 
built an analog synth!  The HZ/HT series have analog filters in them and 
are fully programmable for the filter, LFO, DCO.  Appear to be two 
filters; one for chords and one for melody part.  I put a drum pattern 
on and played some stuff..hehe..these little things aren't bad at all!  
Very inspiring.  I'll have to do some renditions of some of my 80's 
songs on it.  It's a mini key one I got for 70 bucks on ebay.  Right 
after the CZ series in '87 or like that is the date on them.  Internal 
speakers, 8 voice poly, limited memory but good for a few backbone 
tracks in the quick and easy department I can see right away :-)  That 
pays for my curiousity.  The 2090's appear to be dual OTA's at least...a 
string of 4 .05uF caps on one side etc.  Nice sounding filters really.  
I'll try to get some sound samples up in the near future again.  I have 
too many new machines here that aren't on my page.  -Bob
