OldSynths

Hi Einar and list .
I would add to Bonnies explanation .
vintage synthesizers (and most of the new analog ones) are having voltage
control inputs to able the user to control the parameters using external
devices , such devices can be analog sequencers , midi>cv converter ,
voltage quantizer or a CV keyboard .
some of this CV inputs are 1V/Oct and are used for controlling the
pitch/tune of the synthesizer as Bonnie had explain . usually you would want
to connect a controller that would generate this 1V/Oct format such as a
quantizer module or midi>cv .
other CV inputs that are not using the 1V/Oct format can be control by any
voltage source in order for example to control Frequency/cut-off of a VCF ,
PWM etc .
connecting audio in to the 1V/Oct would make an exponential FM of your VCOs
, nice sounds (-:

Hope that help .

Cheers
