Polysix envelope mod?

Polysix envelope mod?

2008-01-09 by Einar Ekström

Hello group,

I'm a brand new owner of a beautiful Polysix that I recently got 
shipped home to Stockholm from Germany. I've been playing it for two 
days now and I really like what I hear and see! Such warmth and 
character to the sound, and the specimen that I got looks almost 
brand new!

Anyway, to get to the question... While digging through the archives 
of this group I found a post talking about an envelope mod to make 
the envelopes faster by changing a few capacitors. There were no 
further details about the mod, nor were there any links, so now I 
wonder if anyone has heard of such a thing? Does anyone know anything 
on this subject?

Allthough I really like the Polysix tone I'd certainly be interested 
in such a mod since I feel the envelopes are rather slow when 
comparing to, for instance my Moog Source, with super snappy attack.

Regards,
Einar

Hi,

I got a polysix a few months ago and I've replaced the NiCd battery, replaced some neighboring chips, replaced a bunch of the buttons, and tightened up the pitch among the six voices.  Compared to my Mono/Poly, though, the attack just isn't snappy enough.  Anyone got any mods to improve the snap?

I searched the archives here and came up with two messages.  One is below (the one I'm replying to).  Another is this one:

Unfortunately, neither have any actual mod given.  Bummer.  

I found this link, which compares attack times in a quantitative way (I love actual data!)...but, sadly, it doesn't talk about speeding it up either...

Looking at the schematic, I see the capacitor and resistors that affect the attack/release time, but before I get out the soldering iron, I'm wondering if anyone has actually tried anything with success.

Thanks all!

Chip
