problem with x2----I'm using steinberg ur22 and two different keyboard controllers

which driver mode are you using in Sonar for the Steinberg?
what are you hardware latency settings? (reported in the Preferences>audio section)
 

Welcome to the forum!
Beagles questions above are the ones to start with, then...
Do you mean litterally : The keys don't make a sound untill they're released? Even if you keep the key pressed for a longer time? Or do you mean you just have a latency of approximately 500 ms? It's good to be accurate with the details.
 
What do you mean by "the keyboard works fine untill you play along a recorded track"?
Do you have another soft synth employed to make the sound before you play along a track or how do you verify they're OK bvefore that? Those keyboards don't produce a sound of any kind, so what soft synths are you using when you play them "by themselves"? Some  soft synths are much heavier on the CPU than others.

OK, I'm thinking it is an input echo problem.  
 
When I first open x2 with input echo off I get no sound. When I press input echo on everything works correctly. Press the key and get instant sound.
When I play the other tracks and try to play along their is a latency issue. The sound is a half second or 500ms too late.
Kalle        The keyboard does make sound if I hold the key down. But, when trying to play along the sound doesn't happen until the key has reached the up position.
when I turn on the tracks to play along with there is the delay. When I stop and play the keyboard it is in the same delay mode. But, if I turn the main input echo on and off. The keyboard produces the sound with no latency

Hello Bob Bone
 
EEEEEHHHHHAAAWWWWW!!!!!!!!  Thank YOU, Thank YOU, Thank YOU!!!
 
You are the man!!!!!
 
Thanks to everyone who responded!!!!!!!

Hi Bob,
I was using LP64 multiband, LP64 eq, and Vx64-vocal strip on first two tracks and only Sonitus eq on the third track
 
Thats it!
Thanks for your help.

Lots and lots of folks find out the hard way that some plugins can really do a number on the latency during recording.
 
I certainly found that out before, as well, and it takes time and sometimes trial and error, to ferret out which plugins are not meant for use during tracking/recording.
 
Some web sites have published latency values for their various plugins, or it can be in the documentation that comes with a downloaded plugin.  Look ahead processing is a term that indicates that some latency will be required for a given effect to do its thing.  Other times, if the plugin doc/ad indicates it is a Mixing or Mastering plugin, it might be a clue that it will add latency.  Convoluted reverb plugins can add latency, as well.
 
(edited to add) If not sure about a plugin's contribution to latency, sometimes I will do a quick search on the web, using the plugin name and the word latency.  If that plugin does add a bunch of latency, there is a really good chance that someone has posted about it somewhere, and you can usually get a feel for that just from the snippets of content shown on the search results pages.
