UPDATE: I was totally WRONG and do not know why my record mode solution worked because I did NOT do what I am about to explain originally which IS the solution...
 
So when you enter new notes into the tracks PRV it WILL create a new take lane BUT if you have Take Lanes for the track already open it will not appear. Also the new lane, at least in my case will be muted so the notes ARE indeed there. The lane is just muted. Holy crap. My notes are STILL being registered on Channel 1 instead of Channel 10 but they are indeed playing. What a mess and a total waste of an afternoon. So it is NOT depending on the recording mode. It is a matter of inputting some notes, breaking open the take lanes (or closing and reopening the take lanes) the Unmuting the new take lane.
 
Sorry for the confusion.
 

No, I also find problems too   :)  Then I reboot...
 
How is that for a new sig?  ;)

Then I reboot...
 

Trying to do a mental reboot right now. Between that and the apparent sleep deprivation experiment my neighbors are conducting on me my blood pressure is probably a tad high at the moment.
 
Oof... no creativity today methinks. And I was so looking forward to it.

I consider the X series software to be a love/hate relationship. 

I feel there is a steep learning curve for longer users of SONAR. (or only me?) That is the biggest part of my frustration with SONAR X series. When I try to do something that should logically work, after many years of using SONAR, sometimes it doesn't. That stresses me out, I write a few posts, check for help or confirmation and then I turn my machine off til the next day.
I am very glad you figured it out. That is the Love part of it. ;)

...It was because I had the track's Take Lanes open and when I inputted the notes it was creating a new and MUTED take lane for those notes. By closing and reopening the take lanes the new lane became visible and once I unmuted it I could hear the new notes.
 

Just curious....   Did you double-click on a clip or use Alt+3?
 

Hi, Steve. Double click and/or select clip > right click > Views > PRV
 
In theory I'd expect those moves to open the single clip but that apparently is not how PRV works in Sonar (and perhaps in other DAWs). It just wants to cram all the clips within a track and even across tracks into one single PRV. I see benefit of multi track editing in the PRV and I learned quite some time ago how to filter out my track notes. It's just the whole notion of not being able to simply select a specific clip for input editing (editing existing notes is fine).
 
I do have it figured out now though and I guess it makes sense even from an audio perspective. The new notes show up in a new clip in a new lane and I'll have to bounce them together which is simple enough. Just took a while to figure out.
 
Also the SoS vs. Comp modes seem to act weird. Like I think when I switched to SoS and was successful at inputting data and having it instantly audible that makes sense. Like it created the new lane without my knowledge (because I hadn't figured out that it was hidden until I collapsed and reopened the lanes) but the notes were audible just like SoS should work. When I tried that again it DIDN'T work and muted the new lane so maybe it got stuck in Comp mode. Possible bug but IDK and what I'm doing now works so screw it.
 
The other option would be to try the Overwrite mode which may indeed just add the new notes to the existing clip but because of my perceptions based on audio overwrite I figured that would delete any other notes in the same time position of the PRV. I may try that later but I almost think I prefer the new notes landing on a new clip anyway.
 
So just another adventure in learning how the heck everything works and getting more stressed than need be due to the severe lack of sleep I'm getting around here.
 
I may just have to set up my own stereo system(s) and show people what exactly ridiculously over the top noise pollution is all about.

Wow, Beep, my hat is off to you. I'd had this problem (or something very near to it) a couple of times and didn't bother digging deep enough to find a solution.
