I want to write a piece from scratch that will have 8 bars with a new bass note every 1/2 bar. Is there a way to put in specific notes in the right place using a RT upright bass instrument?

When I have used chord designations for each bass note and a style, then I get a BIAB rendition that has more than just the simple bass notes. Sometimes there are approach notes or other variations. I would like just a specific note in a specific place.

This would be a type of manual composing in BIAB. Is there a method or a resource you can point me to?

And also how do you preview and pick a specific Upright acoustic bass to play the notes if this is even possible?

Thanks. This seems quite different approach (if possible) than just entering chords and a style.

If all this is doable, then I would like to add in a drum again picking something specific (jazz brushes).
