I must confess that it's hard to use text to communicate timbral qualities to other people. I'm a fan of what I consider "bite" in a VCF. So I'm gonna assume we like the same thing in filter response. My experience is that almost any VCF design with a slope greater than 12db/Oct (18pole or more) gives me the quality I like.....But the 'bite' is more a function of the speed of the CV attack. Some older filers have CV summing amps based on some pretty slow op amps and as these critters age they can slew the attack right off an envelope. This is not a consequence of the core filter design, though. Without going into a lot of (probably irrelevant) comparisons, suffice to say that the CV response of my Omni filter is plenty quick on the uptake. It has no trouble keeping up with the output of Wiard's envelator which has a brutally fast attack time. I recommend it unreservedly. > > Are the VCOs easy to calibrate? > Because I'm not much of techie with these things just yet. > > Can't speak to that. I don't have a wiard VCO, just the digital waveshapers. But I notice that you got a response from Olivier Gerber. Based the meticulous (and gorgeous,BTW) nature of his music - I'd certainly cite him as an expert in keeping Wiards in tune > OK so the Wiard is still in production I gather? you gather correctly. the Wiard is very much in production. I have been getting stuff all this fall. Check out some of the recent mesages from folks who just got wogglebugs delivered. best, -doc
