Hi,
I am having a problem using MIDI devices into Sonar. Input shows on my interface where the MIDI cable is plugged in. The input on the channel is set to interface OMNI but I've tried it on all device OMNI too to no avail. Signal is not shown in the channel level.
However if I right click a control to 'remote control learn' it, my devices show to be sending data into Sonar just fine and I can set them up to control things.
It's several devices plugged into a MIDI Solutions Quadra merge. Currently an example is that Sonar will record some action from my Behringer FCB1010 which is acting kind of as a keyboard, 10 footbuttons outputting note commands. These get recorded to piano roll just fine. My keyboard activity however does not, nor does its sustain pedal, mod wheel etc - though all these things show up on learn.

No issue recording into Sibelius or Protools.

Sonar records anything that gets sent to it. Look at the Event List and you should see all the pedal presses and whatever is sent to it. 
 
Keep in mind, MIDI is not sound so you need to assign the MIDI track to a sound source, such as Dimension Pro or TTS-1 if you want to hear something. Insert a softsynth into the synth rack and then assign the output of a MIDI track to the softsynth. 

You are a bronze member so I am assuming you are experienced with Sonar. Nonetheless, it is not clear that you have experience recording midi from your post. The "remote control learn" working indicates that your hardware is communicating with the Sonar application. That does not mean that your track is properly set up to receive midi, as learning (an application operation) is not the same as recording (a track operation). The failure to record midi suggests that you do not have your input of a midi track properly set to receive data from your midi device, or that you do not have the track armed to record or that the track is not active/selected. If you are experienced with recoding midi and have the track properly set up, I apologize for re-stating the obvious. Provide more information about exactly how you have set up your tracks and maybe someone can be of more help.

When you say "it is registering", do you mean the softsynth, i.e., can you hear the note when you press a key?  If not, then you need to sort this before you begin recording anything.
 

Thanks guys, but sorry yeah I know all this already - as stated input is set properly and I also set it to All just incase. Input echo on, record arm on..simply nothing gets recorded (only in Sonar) when pressing keys on my keyboard but it does when pushing the footpedals for notes instead. Originally I was trying with just a MIDI track but I thought I'd set up it's output to a synth just incase it was necessary to record but it didn't change anything.
Kev, when I said it is registering I meant I know Sonar is seeing the notes because I can use them to control parameters.

I'm inclined to try it without the MIDI merger etc just device>interface MIDI input but the fact that the midi input on the interface is lighting up anyway and it records into other DAWs just fine, I'm guessing this is pointless (and it will also be a trip into cable hell..)

Did you look at the Event List and see what is being recorded? Even though it's only control info, it might give you some clues as to what's happening. 
 
I agree with taking the MIDI merger out of the loop. Process of elimination is usually the best way to fix a problem. Its definitely a problem with your setup. Sonar works quite well with MIDI. 
 
 

Are you absolutely sure that the MIDI track you are recording to is set to the same device MIDI channel that the device is sending? Maybe your MIDI merger is changing things? 

Try making sure that you have looping enabled when recording. I have also noticed this issue when recording audio.
