a) the "nasal and nasty" one is the ARP design b) wait and first hear the upcoming SEM filter. Like the ARP, it is a typical, cheesy state-variable filter with "bad" op amps (LM741s, etc). In general, SVFs are not as "plesant-sounding" as other filter types. This is why I haven't had one in the line until the MOTM-480, and then only because that one is unique. The design is done and the schematic is entered into the pcb system. I plan to do the prorotype layout over Christmas 'break'. Paul S.
