wsg - 2nd circuit

hello! i'm new to this forum and this is my first post. i've ordered parts for the sound lab mini-synth so i guess i'll be around quite a bit Smile

.

i'm building the small wsg random noise synth and i have a question about wiring in the second circuit, according to the original schematic found here:

http://www.musicfromouterspace.com/analogsynth/YOUR_FIRST_SYNTH/your_first_synth.gif

between R2 and C9 you can wire in the second circuit, which is a replica of the first circuit. the only thing i don't understand is what part of the second circuit is wired into that point. is it the part that is equivalent where u1's pin 2 connects to r9?

thanks for the help!

Hi and

!

A bit of hunting around (I knew I'd seen this pic somewhere) brought up this thread, the picture in one of the responses should clear things up for you!

There's 2 attachment points for the 2nd circuit, depending on whether you want a pre-filter ouput or not (not really necessary I don't think...)

Good luck Very Happy

Joel
