"module a-107 is a completely new voltage controlled filter that has available 36 filter types: different versions of low pass, high pass, band pass, notch, all pass and filters with new response curves that have no name up to now. the frequency response curves of the 36 filters available in the a-107 are shown in the graphics at the end of this page. the filters are organized in two groups of 18 filters each. the transition between different filter types within one group can be soft (morphing) or hard (switching).

the filter was inspired by the erwik musikelektronik multimode filter, which is based on the filter used in the oberheim matrix 12 resp. xpander (thanks to jesper erwik johansson for his assistance and permission to use his idea in our a-107 module). the possibilities of the a-107 go far beyond these filter designs as a lot of new filter types are available and the transition between filters can be soft (morphing) or hard (switching) and the filters can be arranged in 64 different voltage controlled filter chains.

the transistion between the different filter types is controlled by two parameters:
* filter step (marked step at the front panel)
* morphing time (marked morph at the front panel)

"This is the first version (serial number 21), with wood side pieces. The central window had come unglued during delivery to me, so I removed the cover and reglued it. You can see some traces of the glue around the window as well as small scratches on the wood in the corners..."
