Hi Martin,

on principle, this IC can be used for a typical four pole VCF as the
Roland IR3109 (in all analogue Roland Synths from JP8 and SH101 ongoing)
or the SSM 2040 (not the SSM2044 which is used in the A-105).

The sound would be in middle between the A-105 and the A-122. I don't
think it is really interesting as an additional module.
