It does this already. If you go into the Track Settings > Inputs > Input CV = CV/GATE AB you can then send external CV into A and a Gate into B. From there you can apply any of the effects and output the effected CV & Gate from the Track outputs.
You can then go further and have another Track look to the same inputs but process them through the effects differently (eg: add +7 to the transpose parameter in the scale effect and you have a 2 note chord).
