In the meantime we developed a different (more modular) conception of the
filter/mixer/panner with separate sub-modules for the main module (voltage
controlled low pass, VCA, panning unit, mute switch, CV inputs for F/A/P), a
filter converter module, an output module and a CV input expansion module.
The filter converter can be used to add more filter types. For the prototype
we have 16 different filters available which are a sub-set of the A-107
filters. The filter is chosen with a 16-position rotary switch. In addition
a bypass switch (VCF bypass) and a VCF output socket (pre VCA/Panning) are
available.

I publish details (including front panel pictures) in the course of this
week.
