Hi there.
Using amongst oothers the Aria Player (as FSZ player for sampled sounds).
So I have several channels for the sampled instruments, and they should go each to another output in the aria players folder.
But whatever I do, all track outputs go to the one and only aria output channel.
With this constellation I cannot work, since I wish to add effects to each output independently.
I had prepared a screenshot but fail to insert it here.
Please, what can I do?

I don't know how many instruments you have in Aria, but one way around this is to use one instance of Aria for each inst. Very simple. Of course, if you have 16 insts. or more, you're going to have a lot of Arias. Which may or may not be a problem, depending on your setup. What I do is to use one or two instances of Aria (Play, Kontakt etc). I use the Pro Channel to adjust reverb on each inst, before they all get sent to Spaces Reverb. You can do the same with the EQ in Pro Channel. This way you can avoid the problems with multiple channels, which can be an issue with Aria, judging from other threads I've seen here.

Best way to do this (with any VSTi) is from the insert synth dialog and choosing all outputs mono/stereo. You can also add audio tracks and change inputs to ARIA, but I forget how intuitive that is offhand.

Thankx for your answers. 
@michael Diemer: Each instance of Aria player would create 16 tracks for one instrument folder, I'd have to delete 15 of them and I'd have to be careful which channel to retain. My RAM is at 16GB, I never tried out before if 11 instances of Aria Players (plus additional other synths) would be overload. Sorry, doesn't seem to be a practicable solution - and in earlier times I didn't have that issue.
@mettelus: What you describe is the default insert dialogue. I just checked it and found there was all as you described. I could crosscheck in ProTools what happens there, just to find out if this is a new issue pertaining exclusively to Cakewalk Sonar.
But to solve the thing here it seems I have to export each instrument track as audio file, open a new session consisting only of those exported files, so I could apply my audio-fx there. Since I have a tempo change in thie project, I'd have most simply saving the old project under a new name, and replace any MIDI- or instrument track by audio files before importing the audio files from my first project to the new one. - But hey, I didn't have to do this in earlier times.
BTW what's up about uploading screenshots here: This always used to work. One picture tells you more than my descriptions. I click on "attach images" and get 2 possible ways: 1) entering a link to the picture in some cloud, 2) "from gallery / upload", but selecting the 2nd option should promt the windows explorer to open so I could pivk the image file from my PC - but that does not happen.

No, you just specify one output when setting up the synth. I think it's "first synth output" that you need to choose. Then each synth only has one output. 
 
Still, I agree it's not a very practical solution. With 16GB of Ram, this gave me trouble too. I now have 32GB but I have in any case chosen the method I described above.

Let's see what will happen next: A new update of Cakewalk by Bandlab is available now, I'll check after installation.

No changes.
I've been placing the same issue at "Make music", there I could also upload my screenshot.

No changes.
But the people from "Make Music" had replied, 
"Thanks for contacting MakeMusic Customer Success. I will try to provide as much help as I can here but this may be outside of the scope of support that I can provide. The routing into VST instruments is going to be based off of the host program and not the plug-in. So, it may be best to also consult with Cakewalks documentation too for more information. 
Your ARIA Player and engine are the most up to date so there is nothing to worry about there. Typically in a host DAW, you would have MIDI channels that route to the separate channels in the Multi ARIA Player plug-in. The plug-in itself then gets routed to the outputs of the DAW. I can't say for certain if this is how Cakewalk works but I would guess that it is similar. " 
So is there anyone over there to please give me a hint how to solve this?
Thankx.

I am not at my Sonar computer right now so this is from memory.
 

• Load an ARIA player (AP) and select the 16 Stereo Out and all outputs.
• This will load an empty AP  and crate 16 stereo tracks.
• Now in AP you have  16 slots for instruments. 
• One of the little numbers on the slot indicates what output the slot is routed to.
• ALL empty slots are always routed to the first output.
• load an instrument into one of the slots 
• I believe you have to right click on the small number that is under the instrument name on the right side (this from memory) 
• This will give you a drop down list to select which output to route the instrument to. 
• Select the one you want and you are all set. 
• Note:  You can set this until AFTER you load the instrument into the slot.

 
I hope this has helped.  I double check later tonight.

Ok. 
The first Stereo out put is 1/2
The second is 3/4
the third is 5/6
...
the sixteenth is 31/32
 

Mad_Musicologist,

I would recommend making a track template for the Aria Player with 16 stereo outs.
That way, any time you want to work with it, all the hassle will be taken out of the way for you.

Step One


Step Two




Of course now you'll have to create tracks with midi data and
send each midi track to a different midi channel within Aria.

And if you don't want all the 16 audio outs going to the master bus,
you'll have to change them all.

Just select them all, and hold down CTRL while changing the bus, like so.


 

This looks fine, I will check. Thankx!
I will tell you if it works.
