[sdiy] JX-3P question

[Richie Burnett]

Can anyone confirm what IC3 (BA662 OTA) is doing in the Noise Generator part 
of the JX-3P schematic attached?

At first I thought it was to allow the noise level in a patch to be 
adjusted, but on closer inspection it looks like the OTA is in some sort of 
local feedback loop, intended to keep the noise amplitude constant, maybe?

-Richie,
