MIDI Pitch Bend and Transpose Question

I don’t know what it’s called, but I think it’s pretty common for people working with samples in a DAW to mimic a second player by taking the first part, pitching it up a half or whole step to use the different samples and then transpose that output back down a half or whole step to get back to the original sounding pitch. I’m wondering if it’s possible to do the same thing automatically in Dorico. For example, if I have a D in an instrument part, I’d like to be able to tell Dorico to grab the nearby Eb or E sample and then digitally pitch that sample down to D with MIDI pitch bend or something similar.

If this is possible, I’m curious if there is a range limitation for this since I think MIDI pitch bends are limited to a whole step. For example, I have a sample library that has a bari sax, but not a bass sax (Acoustic Samples VHorns). The bass sax’s range is a perfect fourth lower than the bari, so I’m wondering if I could write a bass sax part, and if for example there is a written D in the bass sax part, I’d like to be able to have Dorico get the G pitch from the bari sax library and pitch it down a fourth to get the sound of the bass sax D.

Is any of this possible in Dorico? Or am I going to have to export the bass sax part a fourth higher than it should sound and lower the pitch outside of Dorico?

The first thing that comes to mind is to Add Staff and enable independent voice routing. The second voice, which you’ll need to manually duplicate from the first voice, is then routed to the second instrument. Now in the notation, transpose the 2nd instrument down a 4th and at the same time, use the Transpose functionality in the expression map to transpose it back up.

I think that’s what you are after…

EDIT: That’s not what you are after… I re-read the OP like 4 times. I don’t believe this is possible using expression map transposition and samples because if the bari sax doesn’t have the transposed sample, nothing will sound. You will need to use a fixed value with pitch bend, but that range is only a 2nd (up/down) – Sorry for the confusion
