Re: [Doepfer_a100] Doepfer A106-5 filter CV2 question

I am always wondering why no center detent pots were used on the polarizers in Doepfer modules.
I know this is more expensive... but still...

Dieter, is the A-133 implemented with "back-to-back" VCAs? If so a handy improvement for a future A-133-2 would be a switch to select negative/both/positive (or just both/positive only would be very nearly as useful).

Also a sum output, or normal the upper output to the lower output would be nice.

And normal +5V to the inputs so that the units can be used as offsets.

If it's like the A-133, I find the 'zero' point to be very small. Same with the Polarizing mixer.

Hello. I am doing a series on the A106-5. I read that the CV2 is a polarized input so around 12 o' clock the cv input is at zero, at +5 it is at fully positive input, and at -5 it is an inverted version of the cv input.

As long as I understand this correctly, at zero I should have no cv but when I input an envelope it does affect the cutoff a slight amount.

Can anyone confirm this behavior or explain if I am misunderstanding something?


Thanks for any help.
