hi list, what's your opinion on these???: synthfreak: "thanks for the info about the comb. filter,but you still didn't answer my question...should i make a poll about it??i think it would make sense to have a single module combining several notch filters to make a comb.filter,don't you think so??" dieter doepfer: "The term "Comb filter" is a very general term (like low pass). Before a poll is started you should specify the type of comb filter. A phasing type comb filter is already available (A-125). A flanger type comb filter could be realized e.g. with a digital or analog delay. I'm not sure if a comb filter with many notches will make sense at it would very expensive as you need the complete filter electronics (e.g. the electronics of A-121 or A-124) for each notch. I don't think that we would sell many of such an expensive module. I think it is the better solution to use the filters of your system. This might be a little bit more expensive but is much more versatile as the filter modules can be used for other purposes (low pass, band pass, high pass) too. The price for a module with e.g. 4 notches would be about 75% of four A-124 but would have not the features of four A-124. It would be limited to the notch function. From my point of view this would not make much sense - but may be the community has a different opinions. Only a flanger type comb filter might be interesting. But at the moment we are not able to develop such a filter as the bucket bridge devices used in such filter are not available at reasonable prices. We think about a digital delay but there are so many low cost digital delay available at the market that we are not sure if we should add another of these devices. We think it makes more sense to invest our developing resources in devices that are not available now." so...what do you think?? my opinion is that a FLANGER TYPE COMB FILTER would be nice to have(of course,not in a very high price...),ideas??? ===== synthfreak(parallel worlds) athens-greece [Doepfer_a100] group owner-moderator __________________________________________________ Do You Yahoo!?
