As I understand it, you might be able to use a gate signal to trigger the Rev 2's own sequencer but I don't think it's possible to the Analog Keys CV/Gate output to sequence the Rev 2 like you would a traditional analog monophonic synth with dedicated CV/Gate inputs.
Something like an MPC X is only able to sequence the Rev 2 over MIDI, which is completely different to the Analog Keys. In general, polyphonic synths don't really work with CV/Gate, as they would require individual CV and Gate inputs for every voice. Sequencing an 8-voice poly would effectively need to be sequenced as 8 separate monophonic voices!
