RE: [Spam] [Doepfer_a100] Re: News about PSUII, MS20 filter and next batch of modules from doepfer.

ingo,
 
Oh yes cv of resonance would be very nice. I use an Analogue Solutions
MS20 type filter - which is wonderful - and cv Resonance would probably
put it on the top of my most used list.
 
Regarding cv of the filter mode, I assumed if you can put a pot in then
there should be no reason not to have an inline socket that alters the
resistance as well/instead of, I have not real DIY knowledge, but I
remember reading in the ASM-1 construction notes that you can add a pot
to any cv socket, I assume the process working in reverse.
 
Florian, do you know if this is possible?
 
I just love having as many modulation possibilities as possible - worth
paying extra.

	hello david,
	
	from what dieter doepfer wrote, cv of the filter mode
	is not possible with the ms20 filter design, or at least
	it is very difficult to implement.
	for me vc of filter mode is not an essential feature, but
	i would really like to have vc of resonance. that would
	be great, especially on a ms20 filter with it's killer
	resonance behaviour.
	
	best wishes
	
	ingo
