HI Nick G

Your first paragraph says that you use Bandlab for all your sequencing, but in the second paragraph you say you use the BK9 sequencer, so which is it?

If you are doing everything in the BK9 then you need to save the sequence in the BK9 or it will be lost when you change to something else. (Arranger Keyboard sequencers are normally pretty limited though)

If you are using Bandlab then you have to select the appropriate program change and cc codes to tell the BK9 what to do before saving the sequence in Bandlab. (Arranger keyboards tend to have limited Midi capabilities so you may not be able to do everything you want when using Bandlab and the BK9 together)

If you can explain your setup a bit more it will make it easier to help, also how much knowledge about how Midi works do you have so that an answer can be appropriately.
