this is not much of a review and more of an appreciation of great piece of software and really amazing effort done by Blue Hell @ .
WREN is a wall size modular ,with stuff you can't find in the world of hardware ,i believe it's almost entirely programmed by Blue Hell ,over many years ,and it's free .it has over 250 modules to choose from ,installation in windows is very simple ,it default resolution is 88kHz but you can change that to your taste ,it supports midi so you can plug in your controllers and also it's mentioned that it works with Jack for Linux.

Part of my new panel ,i think this will be the last part of the synth i'll be making for myself as i think 5 x 17 inch panels are enough for playing around and making some atmospheres or effects ,patterns ..this is mostly Electronotes panel and i hope i'll make it right ,i am big fan od electronotes ,it is what today are forums like electro-music or muffwiggler ,only better ..for some folks .Just finished the Vewa filters and Option 4 VCO , i hope the rest of the build will go smooth as these ,can't wait to play with the high ripple filter and the additional phases available at the PCB version of the 4 Pole Filter Network .

here's another demo . i just finished this vco from Mordent Design which is actually Electronotes VCO from issue #75 i believe ,it's a thru zero VCO ,the newer Electronotes Zero VCO might behave smoother when crossing zero , but anyway i like this older version a lot too ,here's a short recording of it making vowel like sounds ,this part might not be thru zero i didn't checked on scope .

Another PCB Layout for 4U format ,this is Analog Neuron from NLC ,and CV Twister from Grant Richter .

I noticed i post so many Soundcloud links and very few PCB Layouts ,and even less new Schematics ,so here's a PCB layout for Low Pass Gate and Envelope Follower with Preamp ,adaptation from Buchla Schematics by Non Linear Citsircu  schematics are available on line .PCB Layout is tested and working .
