Hi Dieter > The original Octave Cat filter is nothing but a standard 24dB filter based > on four OTAs (CA3080). I cannot see why it shoud sound so extraordinary. I have/had the Formant VCFs, which are based ont the standard CA3080 schematic. - The 12dB Version is really something on its own and I like it very much (isn't it the same as in the Oberheim SEM module?). - I never liked the 24 dB version of the Formant Filter. Assumingly this dedicated implementation was not good. But there are a lot of synths which sound really great(!) with this filter type: at least different Roland Synths like the SH-2, Jupiter 8, Roland System 700 (maybe some are with BA662 + FET-buffer instead of the CA3080 + OpAmp-buffer). So I think it is worth a test. > published 12dB filter with two CA30380). I thought we have enough filters. > But who knows ..... I think, if you find a catchy name like "Jupiter-Filter" or "SEM-Filter" its reason enough for many customers to buy it ;-))) Florian
