[sdiy] More Progress....

[patchell]

    Got some more stuff working on my synth project.

    Three of the VCO's are now functional.  The pulse output on the
forth doesn't work (odd..), the Multimode filter works, the 24db/octave
filter doesn't :-(

    I have four AD633's on there as well.  Now, I would really like to
know what data sheet I was looking at when I drew up that circuit.  It
was obviously not the one for the AD633!  For what ever reason, I
connected the Z input to the W output.  I can't imagine why I did this.
I must have been looking at a data sheet for some other AD633. ;^)

    I also have four knobs that are buffered by followers (for biasing
stuff).  Should be the most simple module on the whole thing...but, they
don't work.

    Anyway, it looks like it is cut and jumper time, but not tonight.  I
have a model railroad meeting.....
