Hello list,

I'm looking for info on the Roland VCF IC 1R3109 (From SH-101 and others).
Does anyone have a datasheet?  I'm curious if this is LP only, or if there
are ways to configure it as HP, BP or both.  Also, a switchable slope would
be nice.

Any other tricks for this chip?

Thanks in advance

Dave Magnuson
