Usually, synth playing through CV comes in pairs or Pitch and Gate. Some of the others (BeatStep Pro, KeyStep, KeyStep Pro) also have a 3rd CV out for velocity/modulation.
The BeatStep only has the (Pitch) CV/Gate pair.
Of course, as you know, you can use that CV to control any CV input but knowing that the BeatStep is sending it as Note quantized CV
And as you can see, by running the MIDI Control Center while having the BeatStep connected, in the Project tab, there's no settings to change the use of the Pitch CV output.
