Hi all, I just want to post the questions i have regarding the vca module from yusynth. As long as i would like to build up the ac version(for audio?!) here are some questions... If there are allready answered somewhere in the web please excuse me, because of my internet connection speed is very very low. And googling something isn't much fun. Please excuse my poor english.

Question 1: For audio i need to built the ac-version ? As long as audio is always an ac-signal?

Question 2: The best doc i ever seen (thank you yves!!!) isn't good enough for me to complete understand. So there are parts marked as needed for the
ac-version or the dc-version. Should i just leave the parts marked with "**" and use straps to complete the signal path?
Anyone create an pcb only for the ac-version(if I am right with question 1)?

Question 3: I would like to build up two more vco's to get a big sound. Would you build each vco with it's own ADSR+VCA module? Or just the 3 vcos with one vca and one adsr?

Very nice from you to answer!

bye stilz

Hi Stilz,

nice strong aluminium your using there , are you doing stickers ???.

Q3.... try building the Saw Animator & Wave Folder , they are great for fattening out a single vco, but also 2 vco's detuned slightly give a great sound too Smile

Hi Dave. Yes I use 1.5 mm bright aluminium. How i label this stuff I am currently on the way to find out. I tried a few things, but it doesn't look good enough for me. I will have a look at the saw-animator and wave folder modules you have mentioned. Have a nice day men! Do you have an idea of labeling?
