Yes, I feel like I've been reborn. The other main thing we did was rollback the drivers to the earlier legacy drivers. Bob was so patient and chatted me through every step withva lot of humor in between and hecwascin such a hurry to help he burned his hand grabbing the coffee pot. 

 The reason I was using normal midi cables instead of usb (main controller is a Yamaha MOX8) is that I had tried so many tweaks that I thought USB might be the problem and didn't want to add more problems, that coupled with the keyboard has on onboard audio card which could possibly add one more problem to the set-up. Haven't tried it this morning yet as had a morning gig before client comes but I believe all is well. Bob, I have no words to express my gratitude to you and thank you Gio for the PM's and concern and allowing me to take over your thread.

I will change the performance the performance settings to normal.

Would be interested in your Sonar settings-moderators suggesting clicking default config settings which I think defaults to 256. Also other settings under preferences.

Ciao,

Michael

To all, 

I spent several hours talking with and chatting with Mike from Japan, as he was having BOATLOADS of trouble trying to work with his new Presonus AudioBox 1818VSL interface in Sonar X2.

We went through the WRINGER on this one, BUT we got it fixed.  (well there is one more tweak, but he went to bed to get some rest before his client shows up - hope he reads this before his client gets mad).

Anyways, Mike's problems were in crackles and such, as well as it having massive problems with anything below a setting of 1024 samples in the interface ASIO panel.

We reviewed everything, and it turns out that there is a DEFINITE problem with the interface if you actually use the old legacy MIDI ports in the back.  They just freak it out and are the cause of his problems.

He is now running with a total roundtrip latency of I think under 7 ms.  That's as far as we got before his brain's light bulb burned out.

When he wakes and hopefully reads this, he should change the Performance setting in the ASIO panel of the interface to Normal, rather than Fastest.

Other than that he seems to be ok now.
