Input Monitoring latency

What size is your buffer? Generally a buffer size of about 128 samples will get your latency down to about 2.5 ms. Anything above that for inout monitoring will start to give you issues. Also do you have any additional plug-ins across a buss or the master buss? I had a project where I forgto that Ozone was patched across a buss and got all kinds of latency while tracking a vocal until I figured it out.

Looks like the zoom r16 driver is ASIO so as recommended by Zoom definetly use ASIO as your driver mode in Sonar (Options/Audio/Advanced). Also, make sure no other drivers are selected besides the r16 (Options/Audio/Drivers). This confuses people sometimes, if ASIO4All drivers are selected you must first uncheck all the ASIO4All driver to be able to select the Zoom ASIO drivers. This is because the ASIO protocol only supports one driver. And Sonars interface could be more user friendly in this area. But anyways...Also, unless you have some other device that needs ASIO4All, I would uninstall it just to keep things clean. I have no experience with ASIO4All to know if it could cause problems or not.
 
The section under Option/Audio/Advanced/File System is not where you set latency for input monitoring. Leave both Read and Write caching unchecked.

You should probably also check out Zooms site to make sure you have the latest drivers and firmware for the r16.

When using ASIO you set the buffer setting outside of Sonar. I'm not sure if the r16 provides an interface for doing this but if it does it should open up when selecting the ASIO Panel button under Options/Audio/General.

However, I'm not really sure what problem you are having from the description. Are you getting a delayed sound when playing the guitar. Or are you getting crackles like your CPU can not keep up and a drop is about to happen?

What guitar plugin are you using? That could be the culprit.

You need an ASIO buffer of 32, 64 or 128. Since 128 doesn't work for your pc, try 64...
Wait, i just seen your using a Zoom s an interface. If you want low latency, get a sound card /interface, not a recording device. That zoom lacks the drivers needed for low latency. Use the zoom as it was intended. To Record audio.
If you use the hardware as it was intended for, youll have no problems. So i would get a sound card (and stop using the zoom as one)...
Just my simple (yet thoughtful) thoughts....

Thats under the Wdm/km not the Asio. I cant get anything right with the Asio. I will try the Asio with a different buffer and see if that helps.  I just got this as a upgrade over my toneport Ux2. It says it can also be used as a interface.

Crackling noise is usually a symptom of maxing out an input, not latency. Check all of your levels and peak indicators.

 
I disagree. Clipping distortion is distinctly different sound than "crackling" from dropped buffers. I think he's on the right track.
 
I would suggest Googling the Web at large. There's probably an answer out there. You can also Google with site:forum.cakewalk.com appended to find more threads here. I found one that suggested the R16 has an "interface" mode setting. Have you found and enabled that?
 
 

It prompts you when you plug in the USB if you are using it as a interface, i will check and see if there is any other setting that needs to be disabled when in use as a interface. It's definitly not a clipping problem cause I hear the crackling popping noise even at a low signal.
 
I chose this model over the V-Studio 100 since it records 8 inputs simultaneously. I heard the vstudio does not.
I wanted to use this as a interface and portable recorder since I play in a rock cover band and it would be nice to record practices and shows. hopefully its able to do that.

Actually, if you check out the r16 they market it as an interface with low latency ASIO drivers and comes with Cubase4, as well as a control surface. Perhaps he just doesn't have it set up correctly in Sonar.

Never hurts to eliminate common problems first.

 
True. But since a larger buffer elminated the "crackles" that suggested it is indeed a buffering problem. A larger buffer would not affect clipping. No biggie. Just wanted to head off what I thought was a "red herring".

My money's on the amp sim as the culprit. Its own latency is forcing the OP to set the buffers lower than they might otherwise require for acceptable latency.

I was thinking the same thing at first, but It happens even with a dry signal.
