Can I use combinator to play notes other than the ones I select?

For example, I hit C3 and it plays C4.

My plan is to put multiple of the same instrument in the combinator, one for the note I plan to play, another, for example, 4 half steps up and another 3 more half steps again to play major chords

If you have other methods of doing the same thing, post them

Not Bome's virtual keyboard, though, I already have this but only want to use it below C3, and as far as I know I can't pull this off with Bome.

Also, if this is somewhere already, I couldn't find it in the search because I can't think of any specific enough words to filter out the wrong results

Yep , the Combi-device can be used to achieve this ... (chords) ,

(and i dont know if there are any other methods ... , cos when i need a chord .. i just hit it on me keys )

Greetzzzzzzzzzzz

Nevermind, figured it out
