I suppose that your CV source (Midi-toCV ) is a bit out of scale and the
two existing VCOs were adjusted to fit to the interface. This would explain
why the adjustment of the A-111-5 by Andy of Emis did not exactly match to
your CV source. When you have time I'd (and the measuring equipment) I'd
recommend to measure the CV source some day to avoid problems with other
VCOs in the future.
