I'm not seeing how a click track can waiver, but they sure don't stay in  sync... 
 
Project has hihat click on track 1. I solo and play while trying to find bpm. It matches up best at 123 but......... I tried to quantize the hihat(it's just a track of audio now). The fellow who did it is out of town so I'm trying to figure it out. The only thing I can guess it's not a metronome, it's a looped self made click? If so, quantizing to 123 bpm 1/4 notes should have cleaned it up, no? 
 
Pardon me, is my noob showing?
 
 

Hi. I believe that you can use audiosnap for that. Choose extract beat from chosen track.
Best of luck.

Off to watch the audio snap vid!

Ok watched 3 videos, back to Sonar....

Well, it ain't working, guess I'll watch more vids.
 

Try using audio snap to extract midi. Paste it into a midi track, then sync to that midi track.

This is I think, a case that shows how 2 independent devices need to be linked together via a sync protocol to keep the timing together.

Does the 2488 have an spdif output? If it does but your sound card doesn't then it's a case for using your onboard audio. Mine has a spdif in and out. Maybe yours does too.

I don't know what a 2448 is... I'm assuming some kind of outboard synth/gear. If that is indeed the case you need to learn about MIDI Sync and/or Internal vs External Sync.
 
To put it simply... when you are recording/doing stuff all inside Sonar it will always sync up because it is using the "internal" clock. Once you start using outboard stuff that have their own clocks you have to "sync" it to Sonar... otherwise things will drift or otherwise go nutty. This applies to synths or things like tape/ADAT machines.
 
I do everything inside Sonar so I cannot help you beyond that but if this is indeed your problem then you gotta read up on how to sync outboard gear to Sonar. There are large swaths of the manual dedicated to this topic. It's not THAT complicated but you have to know what to set and how.
 
If that is not your problem then my apologies.
 
Cheers.

It's a Tascam 2488 Multitrack. I exported (tracks as discrete wav files) them to a 2488 Neo and they did fine.. I'm gonna try the midi idea in the am. I used a program from the web to tap my space bar to the beat as it was playing, and the magic number seems to be 130 BPM.. Sonar found it to be 133 but I am not sure I used it correctly. I can now put a drum track to it!!!
 
Thanks for the help. I am writing down the  SWA X2 vids I need to watch a few times to grasp all this cra....technology.
I am now 25% thru them.....
 

I have a Tascam 2488. It has spidf. It can also be midi synchronized so it moves with sonar now time. Start rewind fast forward. And you can use it as a catch hardware controller. The faders are not motorized, but when you move it past the current value at catches and now controls the value.

It is only 44.1. When I use it with the RME, I slave the RME to the Tascam and the Audient to the RME. This works. I generally do not midi sync. You cannot slave the Tascam to the RME via spidf. This gets me to 24 inputs at 44.1 24 bit.

You can export many tracks at once by using the insert button to select multiple tracks but they export to the fat partition in real time mono. This means exporting eight one hour tracks takes eight hours. I leave it overnight.
