I’m getting a weird split behavior, I submitted a ticket as well but thought I’d share here in case others are having the same issue (or someone can tell me if I’m just doing it wrong!)
Set up a split with the new Jazz Upright Bass softbass (Sampler) and a Rhodes on the right side.
Set keysplits like so: part 1 C-2 to E3 – part 2 F3 - G8
Set Octave Transpose on part 1 to -1
The bass part is doubled by an octave instad of transposed.
Hmmm… I’m trying the same settings on AstroLab 2.0, and it is working as expected.
