Being new to this, I stumble around a lot, lots of trial and error to get things to work... Learn a lot that way, but one thing I've yet to fully understand is when I see something like this, how does that read? how do I interpret this?  I "THINK" I somewhat understand it, but help is great appreciated it.


These are what I see as input options from Superior Drummer's output for track assignment.

S1/2: Left(mono)
S2/3: Right(mono)
S1/2/S2/3:Stereo
S3/4: Left(mono)
S4/5: Right(mono)
S3/4/S4/5:Stereo

What is this referring to? Inputs on your interface? If so that's set up a little weird. Usually there would be 1/2 left mono, 1/2 right mono then 1/2 stereo meaning the first two are input 1 and input 2 (which is how some programs and interfaces view the channels and I personally prefer it that way) and then the stereo version is just both inputs being treated as one stereo input.  

It refers to the way your soundcard/interface inputs are displayed inside Sonar.

It's quite simple - if you're recording a mono source, pick one of the mono inputs.

If it's stereo......you pick stereo

This way, the track interleave will be set automatically - you don't have to worry about it and you'll see the appropriate number of waveforms in the track/clip  when you record.

Beep I've seen numbers like this before - I think it varies from interface to interface - I don't think Sonar influences this, but I'm not 100% sure.

Those are input options to a track from the output of Superior Drummer 2.

I believe they part of the track name that SONAR creates when Superior Drummer is inserted into a project. Aside from the obvious relationship, I never bothered to study it beyond that. There is nothing in the documentation that offers an explanation of why Toontrack uses those names.

Edit: I see the OP offered a little context. FWIW, these names don't have much meaning without context.

OK. That's how your soundcard inputs are laid out in Sonar. (I don't think you have yours numbered quite right.) For example, my Delta44 has 4 mono inputs. 1, 2, 3 and 4 that correspond to the 4 input jacks on the Delta44. So my input options are: 

Input 1 Left (Sonar will record a mono track if you select this or any of the mono inputs) 
Input 1 Right (which is really jack 2)
Input 1 Stereo (which is jacks 1 and 2 and Sonar will record a stereo track if you select this option or any stereo option)
Input 3 Left
Input 3 Right (which is really jack 4)
Input 3 Stereo (jacks 3 and 4) 

Most soundcards are laid out in a similar way.

Okay... it's just mimicking outputs on a hardware console. 1/2 is supposed to be two mono inputs so you can have either 2 mono inputs or one stereo input. For inputting from a drum synth you'll probably best off using the stereo inputs for each kit piece but make sure that you are indeed only getting one kit piece on the stereo input (if there is two pieces on the stereo channel figure out how to get the drum synth to output that piece as stereo or if you can't choose the MONO input 1/2 left for one piece on one track and then MONO input 1/2 right for the other on another track).

Sorry that's a little garbled. You should watch the Drum Production vids in the Sonar University stuff. Seth does a good job showing how to set it all up. If you need extra help I can dig up a step by step tut routing BFD which is probably similar.

Well, like I said the names are a little odd. The stereo pair S1/2/S2/3:Stereo is actually made up of S1/2: Left(mono) and S2/3: Right(mono) So it appears that Toontrack used even numbers to indicate a relationship between odd numbered mono tracks. The "S" is for "S"uperior Drummer. At least, that is my best guess. There is nothing in the docs. Probably a better question for the Toontrack forum for a definitive answer. Never looked that closely at the track names created when inserting a synth, just renamed them to something meaningful.
