If you ask those questions that strongly susggests that Csound (or your Csound code) is not handling this plugin correctly. "Frequency" is an audio rate port that would normally receive the frequency 'control voltage' from the keyboard. This is an exponential control: +/- 1 --> one octave up or down. If you send it (midi_note_number - 60) / 12 as an *audio rate* signal it will do the right thing. "Octave" and "Tune" are control rate ports normally linked to GUI controls. They are the 'manual' frequency controls, "Octave" in steps of an octave (it expects integer input), and "Tune" with a range of one octave. In Csound you don't need them as you can have the same result by adding the same values to "Frequency". Finally there are three modulation inputs (audio rate) and their corresponding gain controls (control rate): "Exp FM" "Exp FM gain" e.g from an ADSR "Lin FM" "Lin FM gain" e.g. for vibrato "Mod" "Form mod" waveform modulation The latter two have bad names, they should have been "Form mod" and "Form mod gain" to be consistent with the FM controls. If you set "Exp FM gain" to 1.0, then "Exp FM" has the same effect as "Frequency". Again, this plugin is meant for use in AMS. A csound oscillator normally has just a single frequency control and non of the FM related ones (they are replaced by code).
