Hi Bob,
thanks for answering.
I confirm it works as expected.
I should have done some tests myself, but i was
fooled by SigmaStudio manual where, in VCO description,
is stated:
The input value may be from zero to one (5.23 format), and the VCO linearly interpolates its derived value into an output frequency
It says the value has to be from zero to one.
Many thanks.
Tom
