Have the possibility to have more tracks on the same audio track ex:(2 guitar track with the same effect and on the same track output) .. because when using more vst (guitar) it becomes very rough to have many tracks ?
 
Is it possible to introduce that
 
Thanks you .. sorry for my english

I think you want to create "sends" on the tracks in question with the effect(s) desired in the send fx bin instead of the individual tracks that contain the "sends".
 
While sends are the traditional ways of doing this, Sonar also recently gained "aux" tracks that work like sends but are grouped in the track pane whereas sends are down there with the busses.
 
Set your effects in the send to full wet and blend vis the send levels in the sending tracks.
 
Hope this is what you mean and helps.
Your english is fine btw.

Thank you for your prompt response
 
Yes I saw the auxiliary tracks on the track but both are overlapping ( track on track the sound is bad :(( The sound is not like on two separate track
 
Im using toneforge +effec vst so is really harder for system .. so when im using somes tracks with this one ive often drop out :(( thats why i woukd like to find a solution

You can also set the output of your desired tracks to a Bus and then put your effect in the Bus. That would combine your 2 tracks and let you use your VST on both at the same time.  Make sure you route the Bus output to your main output as well. 
 
This is very similar to using Aux tracks. If you send both tracks to an Aux Track then there should be no difference in how they sound unless the combination of the 2 tracks is causing clipping.

Also.... when sending two (or more) tracks to a stereo Aux Track or Bus, if the clips/tracks are mono you can also control the Pan of each track, along with EQ/comp, to help generate some "separation" even though they're routed to the same location.  
 
As far as system performance goes, does increasing latency allow you to keep multiple instances of the plugin?

Without knowing what kind of material is on the tracks: Could this be a phasing problem (opposite phases cancel each other)?

Hi 
 
If the t1 t2 t3 ect ... the sounds would not blend .. it would be wonderful .. is there a solution for the T1 auxiliaries T2 ect.

Hello, I tried to put my track separated by different buses and also put the effects on the bus .. the problem of heaviness not changes.. and I still have drops out: (((the best solution Would be that the sounds do not mix in auxiliary T1 T2 T3 ect ... Because the sound is too bad when it mixes with the other guitar track

Processing two tracks with the same FX, and then summing won't always produce the same result as summing the tracks and then processing them, especially with dynamic, input-level-sensitive FX like compressors. Also if the FX are insert-type FX where you generally want 100% wet output, you will always want to set the Output of the track to the bus or aux track rather than using a Send. Using sends, you will not get more than a 50% wet signal unless you use a prefader send and drop the output volume of each track to -Inf, which would be unecessarily complicated.

When you run two or more tracks into an effect on a bus you are increasing the input gain into that effect. Which means anything that compresses or generates distortion - such as a guitar amp emulator - will respond very differently to how two instances of the same effect put on the tracks themselves would respond.

Expect more compression and distortion, especially on low frequencies. Also the sound 'cleaning up' a bit as the guitar volume drops as it sustains won't happen, or at least won't happen in the same way.

If you run the effect on a stereo bus as a 'dual mono' processor (which a plugin may or may not let you do) rather than as a stereo processor you may be able to avoid some of those problems. Otherwise what happens on one track will quite likely have some effect on the other. Balancing between the two guitars may also be difficult.
