Too many tracks?

When using a VSTi with many instruments loaded into it (Kontakt for example) there have to be MIDI tracks assigned to each of its instruments. But if you want to control each audio output of this VSTi, you have to create additional (for example 12) audio tracks. So it is 12+12=24. Bigger projects require another instances of the VSTi with new tracks assigned to it.
I had same difficulties with Pro Tools where 24 tracks for Kontakt have to be created. In FL Studio there is no such problem - other architecture.
Is it possible in Sonar X1 to solve this problem? Combine somehow audio and midi, and new instrument track will send midi to VSTi while be processed by effects? (Maybe i should send a feature request then)

[shudders] simple instrument tracks are a bit buggy... you can use folders to group stuff, or "hide" tracks you don't want to see in the gui

Although I have heard people report issues with Simple Instrument Tracks,  I have never had a problem with them.  My normal drill is to use Simple Instrument Tracks for single instruments (e.g., Ivory Grand, SI Bass) and individual MIDI/Audio tracks for multi-timbral instruments (e.g., Session Drummer).  I also use separate tracks for RealGuitar because I want two MIDI tracks: one for notes (chords) and one for strumming patterns.  Some people use separate MIDI tracks for instruments controller by KeySwitches so their score is not screwed up by random bass notes.

I put MIDI tracks in one folder and audio tracks in another and then hide the MIDI folder once the arrangement is pretty well set.

A little off-topic, but once I freeze a simple instrument track, I mute it and drag the audio to a separate track.  When a project is close to completion, I have the original source project and a separate file from which I have deleted all the MIDI.  The final project I mix is nothing but audio (and as I said, I save the source).  Other people here will disagree or have a different style, but I like a nice, clean final product with nothing but audio on the consolde, no hidden tracks, and no extra CPU load.

Didnt mention before, i cant check it out because my Sonar Trial expired.
So, what I'm trying to understand, will it be like: Kontakt 5, with 12 simple instrument tracks that control instruments inside Kontakt, with Kontakt's output routing to these simple instrument tracks?

No - because you need separate Midi tracks (and audio tracks) for each Kontact instrument.

No you don't. You need a separate instance of Kontact for each instrument, but one simple instrument track for each of those.  The simple instrument track eliminates the need for a separate MIDI and Audio track for each part. 

I know some people have reported problems with instrument tracks, but people report bugs all the time that aren't really bugs. 

Am I missing something? If the OP wants to load 12 instruments in Kontakt and have separate audio track for each, how could he use a SIT when inserting that one instance of Kontakt? . You can't do that without having a separate MIDI and audio track for each instrument, can you? . I got curious: How is this done in Fl, if you don't need as many tracks? . (If this post looks strange, it's because I tried to work around the Firefox paragraphing problem)
