"On another note"

"On another note"
 

How would you shift a conversation in Spanish by saying something like, "on another note" or "on a separate note"?

Thank you!

Common expressions in Mexico: "pasando a otra cosa", "cambiando de tema", "y hablando de bicicletas..." (this one is to introduce jokingly a topic that had nothing to do with what we were saying).


- Cambiando de tema, ¿sabes si Rodrigo sigue en el hospital?

- Pasando a otra cosa, ¡ya me compré un coche nuevo!

- Oye, y hablando de bicicletas, me voy de vacaciones el martes.

Welcome to the forum, smbras. I'm not a native speaker but I've said it [rightly or wrongly] as capítulo aparte,...

Great answers! Thank you

Very interesting! The last one is funny. And I should have thought of "cambiando de tema." That one sounds right. "Pasando a otra cosa" sounds good too. Thanks!
