Hi All:
I did get my VCO working yesterday but spent an inordinate amount of time
calibrating it. I really love the instructions (especially the theory of
operation). Yes, I had problems with the power cable and that added to the
time it took to calibrate it; I was able to fix the pins on it properly.
I do have a question for Paul and other VCO users: I'm experiencing a
frequency drop when I switch from soft to hard sync (with nothing at the sync
input!). At 1440 Hz in the hard sync position, it drops to about 1360 Hz in
soft sync. I don't hear a pitch drop at around 90 Hz (I don't trust my freq
counter at this low freq), so it seems to scale differently in the hard and
soft sync positions. Does anyone else notice this behavior?
Oh yeah! Filter 12 -- the filter that filters out all JB's bad jokes while
passing the incredibly small amount of content on the MOTM Onelist. Its
called a Low Brow filter. I've never used a Serge Variable Slope filter, but
Serge T. had said that it would be the best compliment to the Extended Range
Filter I already have -- an interesting filter concept if nothing else.
