I know you say you’re fed up with duping tracks/parts, but do you use Ghost parts? I create a 2nd midi track with 2nd VSTi in place, then I ghost copy the parts (i.e. I can edit one, they all change). I find the advantages outweigh the extra ghost part copying… First is that I can easily see two tracks in the project, and therefore two VSTi’s (which you can’t see so easily see when using Sends, you have to ‘remember’ they’re being used). The 2nd is that I can apply transpose or velocity adjustment using the status line to one of the ghosted parts which can be really useful for blending the instruments together, e.g. octave doubling of flutes and clarinets, or e.g. octave doubling of moog + MS20 bass.
