I’ve been using the midi outs on Motif instead of USB for years because when I use USB it hangs and hiccups consistently no matter what version of windows or driver version.  I have windows 7 and the latest Yamaha USB driver.  What gives?  I can’t believe this is just me.

No, hiccups could be because you did not setup the driver properly. That is usually the cause - it is not just you - everyone with the driver improperly setup is likely to get hiccups.

Can I get the instructions to properly configure pls?  TIA

You don’t say what software you are trying to setup. So we can’t really tell you much…

Sorry.  I have Windows 7 64 bit with Sonar 7 and Sonar X1.  I have the latest Yamaha driver for Windows 7 64 bit. Is there anything else you need to know?  TIA, Larry

What you need to do is select the Yamaha USB-MIDI driver and tell us exactly what version - this is important since you say tried several (?)

Go to your Windows 7 CONTROL PANEL
Double click the Yamaha USB-MIDI Driver icon to open its Control Panel
Let us know the version and what happens.
Does the computer recognize your Motif ES?

Next in Sonar’s documentation you want to make sure you have setup to use this driver for MIDI input.
You don’t mention what your audio interface is, are you using one? Or are you only using Sonar for MIDI? We ask because the audio interface if not setup properly can be responsible for clicks, pops and erratic behavior of the audio signal.

I have vs 3.1.2. I have tried older versions of the driver running with xp and motif over the past 8 or so years and have had the same issues as now- no sound and then a burst of notes after a delay and other like anomalies so I gave up on trying to use the motif USB and opted for the ux256 for midi which ran fine. I am now running the tascam us 1800 as my audio interface.  I am only having midi issues. Audio is fine.  Sonar is recognizing motif.  I need to use the USB now because I want to be able to use the plg150ap.  Thx

Maybe it’s your computer or the particular USB port. Has it been the same computer throughout the 8 years? It is unlikely the MIDI driver but anything is possible. What happens when you record audio through your audio interface?

What are the specs on the computer - do they exceed those recommended by Sonar?

I just bought a new Dell Inspiron.  I am having the same issues on both this new computer and my old Dell.  I have had no trouble with the audio.  What do you need for proper configuration of the driver.  Are there some settings I can play with to see if they make a difference?  To me, it’s either the driver or my ES, but since you mentioned others having trouble with the driver I thought I’d start there.  I would like to update my OS on the ES but don’t have a way to do right now since it needs to be through the card reader.

What firmware is in your ES?
