I know the difference i just had heard hz/v mentioned for them. A guy playing his with a MS-20 etc.

The 200 and 101 oscillators are a non-standard 1.20v/oct

hz/volt is more of a japan convention: korg, Yamaha, etc...

i can get mine to tune to other 1v/oct gear but its prone to drift as the controls are so course.

i was hoping to get a mod enacted with a fine tune VR so one of the swing inputs was always 1v/oct and could be calibrated as things settle and drift...

CV

While the concept of CV (Control Voltage) was fairly standard on analog synths, the implementation was not. For pitch control via CV, there are two prominent implementations:

• Volts per octave. This standard was popularized by (if not created by) Bob Moog in the 1960s; it was widely adopted for control interfacing.One volt represents one octave, so the pitch produced by a voltage of 3 V would be one octave lower than that produced by a voltage of 4 V. Notable followers of this standard include Roland, Moog, Sequential Circuits, Oberheim and ARP.

• Hertz per volt. This method (used by most but not all Korg and Yamaha synths) represented an octave of pitch by doubling voltage, so the pitch represented by 2 V would be one octave lower than that represented by 4 V, and one higher than that represented by 1 V.

The following example table demonstrates some notes and their corresponding voltage levels in both implementations (this example uses 1 V/octave and 55 Hz/V):

Maybe in this someone can answer whether or not the 200 (and 100) are HZ/V as opposed to V/OCT a...
