Polivoks Party on Midsummer Night :)

Breadboarded the "Bareille" Polivox clone and just did a test! Works nicely and does some very civilized filtering, when the resonance turned down, becomes a screaming beast when resonance turned up... Still to test: frequency modulation of the filter, have to connect a lfo voltage source and see what happens <img src="http://midibox.org/forums/public/style_emoticons/default/smile.gif" class="bbc_emoticon" alt=":)"><br> <br> Will build a stereo variant on veroboard primarly to be used with the MB6582 later, the rawness and the extreme resonance should suit the SID sound <img src="http://midibox.org/forums/public/style_emoticons/default/smile.gif" class="bbc_emoticon" alt=":)"><br> <br> Highly recommended because of very good performance for material cost - less than 20€ in parts, just 7 opamps, about 25 resistors, two 1uF tantals and three pots, +15V/0/-15V or +12V/0/-12V PSU (e.g. from MBFM) required.<br> <br> Have fun!<br> Peter

Brathering - it is just an old used one from ebay, but works nicely and brings back that late 80s flair :)

wicked1 - thanks! It is really not difficult to build (the lower right OpAmp in the bareille schem misses +15v/-15v, otherwise it works great) ... Some kind of lfo modulation voltage source for the filter would be good, otherwise you end up only with filter and resonance control, which sounds already really good. I was especially surprised by how good the low-pass filter sounds (with resonance turned down).
