Can I "link" two identical parts of different instruments?

[lmv]

I have these two parts in the composer that play the exact same notes but output to different instruments. I know I can Ctrl+drag the part from one instrument to the other and both will play the same notes, but then editing it is a pain because I have to keep copying/dragging the part after every change. Is it possible to link those parts in Waveform so that when I edit one part the other one is updated automatically?

A rack will let you put 2 or more different instruments on the same track, with each receiving the same input at the same time.

Maybe you should give "linked midi clips" try.

Or nest the two synths into a Rack...

in the same way than for audio, you insert a "send aux" utility and a "return aux" utility in order to "route" a lot of different audio tracks to one unique effect for all the audio tracks (reverb, compressor, etc...),
in your case, you do the reverse (with the "midi patch" utility) !
have you tried to insert in your MIDI track 1 (containing your MIDI clip), a "midi patch" utility, in order to "route" the same midi signal through various different midi tracks, each other MIDI track with the same "midi patch" utility and a particular and different VSTi ?

As an "old" tracktionner, I do this since the beginning of the Tracktion software, and you can play different tracks with only one midi clip in only one midi track...

My 2 cents...
