Each DAW has a unique way of handling Kontakt's multi feature. This article will show the process in Cubase by using Instrument tracks as outputs. For information on using multi's in Cubase's built-in 'racks' feature, please see here.
1) With Cubase open, the first thing we need to do is add an Instrument track. Select the + to add a new track.
In the window that appears, select Instrument, as well as an instance of Kontakt.
2) With Kontakt open, load up the patches you wish to use in your multi. For this example, I'm using the 5 Performance Legato patches from Symphonic Strings. By default, you will see that the MIDI channels will automatically assign depending on the load order.
More often than not, it's useful to have different outputs assigned. Provided that you have Kontakt set up to do so (see here if you haven't), you can go ahead and assign different outputs:
3) Now that Kontakt is set up, we need to create the MIDI tracks in Cubase. It's important that your MIDI tracks are 'linked' to the existing Instrument track, so right click to add your MIDI tracks:
As we have 5 tracks in total, we need to create 4 MIDI tracks to make up 5 overall.
You'll see the MIDI tracks appear below your existing Instrument track. Rename these accordingly and make a note of the MIDI number the tracks have been assigned to. This will coincide with with MIDI values set in Kontakt.
4) Next, we need to set up the outputs. In Cubase you'll need to first activate these outputs separately, so press F11 or go to Studio > VST Instruments from the top menu dropdown.
Once opened, we can activate the outputs by selecting the furthest right arrow:
As with the MIDI tracks, we have 5 instruments in total so we'd want to select 4 additional outputs:
5) With the outputs now active, we can now use the Hide/Show Automation button in Cubase to view the outputs. Remember to select this on the main Instrument track, and not the MIDI tracks.
The Outputs will be unnamed, so you'll need to name these to correspond to the Instruments. You can refer to the Kontakt outputs to make sure you've got everything correct.
Here's an example of what ours looks like named:
6) You're done! You should now be able to play each MIDI track each with their own individual output.
