I've uploaded a 1U motm style Schaeffer front panel design for a Buchla
194 fixed bandpass filter with audio mixer (look in the Buchla Type
directory for Buchla194.fpd). It is a nice little filter
with 4 fixed bandpass outputs (and it is relatively easy to build). I've
added a 'standard' 3 audio input mixer with attenuators, and a switch with
associated output that selects between the original mixed audio and the
mixture of the 4 filter outputs. One suggestion: I found that it was
advantageous to amplify the filter outputs to levels 'close' to what the
other modules in my system put out.
