@Bill Phillips - we've identified the issue here (it has to do with the clip gain region crossing tempo change boundaries).  It'll be fixed for the general release.

Disable the MIDI output of your drum VSTi:



Or alternatively set the MIDI input filter on your recording MIDI track to "All External Inputs"

 

Currently the PC76 U Type (or the PC4K S Bus Type - they're the same plugin with a switch to change type), and the ProChannel EQ are the only two PC plugins that can be controlled via the Mackie.
These were "special cased" by Azlow3 in the Mackie Control source code - all other plugins have to be in the main track FX bin to be controlled.

There may be a way of supporting them in the future, however the difficulty is the risk of breaking the many Mackie Control emulations.

It's something I'll look into when I get the chance.
 

This is how I do this:
1, Open up project 1 & 2
2. Go to Project 1, select all the tracks you want and save as a track template. 
3. Go to Project 2, insert the track template
4. Go back to Project 1, select all the tracks you want, and Copy Special (with all options checked)
5. Go back to Project 2, make sure [1] the first track of the newly created track template is the active track, and [2] Now time is at start
6. Paste Special.

Look at the nudge settings in Preferences->Customization->Nudge.

You can configure up to 3 different nudge timings, and use the keypad (with numlock ON ) to move the selected clip(s).

When using the PC4K S-Type Bus compressor on a track, and enabling the side chain, it appears for me as the following:



 

Are you in offset mode perhaps?

That's fine as the 2i2 only has 1 x stereo pair.

However, when you go to your track inputs you'll now get the choice of choosing the channels:

Have you tried disabling handshake on the Mackie Control properties?


 

I'd strongly advise you to keep SONAR Platinum installed so that all the 3rd party extras that come with it will continue to work with Cakewalk by BandLab.
Both can exist happily side by side.
You shouldn't encounter much of a learning curve moving to Cakewalk by BandLab - the program is basically the same, with a few enhancements and a huge amount of bug fixes.

Has that note been accidentally assigned to a command within Keyboard Shortcuts?

Ok, that's your Roland audio interface driver crashing.
There's a couple of things you could try:
1. As you've switched back and forth from ASIO to MME, your AUD.INI file may be a bit messy with the measurements from the different modes. This can sometimes cause crashes. If you delete it (when Cakewalk isn't running), Cakewalk will create a brand new one when it starts. Its located in %APPDATA%\Cakewalk\Cakewalk Core
2. A Windows update could have messed about with your audio interface drivers. Re-installing them should normally fix this. I'd recommend deleting AUD.INI as well, after the driver reinstall though.

Does it not just import at the current Now time? 
Maybe just press "W" before you do the import.
 

Take a look at this: https://www.ghacks.net/2012/12/27/remap-your-mouse-buttons-on-windows/
From what I can tell, it lets you assign hotkeys to load different mouse profiles.
So you could map (for example) CTRL + ":" set the buttons to left handed, and CTRL + SHIFT +  ":"  to swap them back to right handed.
Note: There may be better programs out there - this is just one that I found in a Google search.

Yeah, I get this sometimes.
I've never worked out why, but putting in a blank measure sorts it.

I'm not seeing this behaviour, it's working fine for me.
Do you have any lenses defined, or screensets or mix snapshots on that project?
There was a recent post regarding a similar issue:
It turned out to be a lense issue. Setting Lenses to None fixed it for him.

Try this:

This method still works for me.  I don't recall having to change the registry... although I suspect I changed it in Preferences before the option disappeared.
The things I need help for are less well used ones, rather than standard workflow tasks (which usually means they've not changed since SONAR), so the fact that it's out of date hasn't been an issue for me so far.

For this kind of editing, I guess it might be easier to export to Audacity, do the change speed, and import back into Cakewalk.
It's a pity Audacity can't be added to the tools menu (well, actually it can, but it doesn't work quite as expected). 
SoundForge works so much better for this kind of thing, as you can fire up SoundForge directly from Cakewalk, do your edit, save and it's automatically updated within Cakewalk.
