I was using BB 2018 build 507 and I happened to notice it launches a process called System - 'NT Kernel & System' that hangs around 25% cpu usage continuously in Task Manager. I installed BB 2018 build 508 and it does the same thing. This causes my System Idle Process to be around 73% whenever BB is running. The bbw.exe process is showing 0% cpu utilization during the entire time.

I see the same process launched when using RealBand 2018-4-0 even if the program is minimized and not being actively used. I never noticed this constant CPU usage before and just wondering if it is something new in the 2018 versions? If I close BB or RealBand my system Idle process returns to 98%.

I'm using Windows 7 on an AMD quad core CPU.

Perhaps it has always done this and I just never noticed it before. I would appreciate it if someone could verify this happening on their system.

Thanks in advance!

What Audio driver?
Could be that an ASIO 'always On' driver or such has been initiated by launching the program.

For what it's worth I often use a W7 64 AMD based system also and I have never seen that. I would notice something using 25% processor right away.

I'm one of those that, when it is time for music, I make sure all un-needed processes are removed/killed and often leave Task Manager open for a few, even if just to see how long it takes to truly settle down.
In recent Beta testing this was normal for me to watch what was happening, performance wise, for both load and unload as well as while running it.. don't recall seeing that behavior at all..

Thanks for the reply Rharv,

I checked the audio driver in BB and it was set to WAS, 'Output always on' was also checked. I unchecked the output always on and tried changing the audio driver to MME for both input and output audio but this didn't change my CPU utilization. As soon as BB is closed, the CPU goes to 99% idle.

Realband was set to WAS also and output always on was checked. I tried unchecking 'Output always on' but this had no effect. Something did change though when I set the audio output driver to Microsoft Sound Mapper. Then the CPU utilization went to 99% idle with Realband running. It stays this way until I check the 'output always on' box, and start playing a song in Realband. As soon as I hit the play button I see the process NT Kernel & System jump to 25%. It stays at 25% if I stop the song playback and minimize Realband.

If I leave the audio output driver set to MME and uncheck the 'Output always on' box, then the NT Kernel & System process goes to 25% while the song is playing but drops to near 0% when the playback is halted in Realband so this seems to act a little different than it did in BB.

Easiest way to find out what's using CPU cycles, start Task Manager, go to Processes tab, sort by CPU. You can also get even more information from Resource Monitor:

Thank you VideoTrack,
Yes, that is the method I use also. The image below is what I see in Task Manager when running RealBand. The Realband application is open but doesn't have a song loaded and is minimized. Audio Driver set to MME and 'Output always on' is checked. The second entry in Task Manager shows 25% utilization and it will stay that way until I uncheck the 'Output always on' box when the output audio driver is set to MME.

Hmmm...

Some sort of feedback loop?

Output connected back to input, creating a self-perpetuating loop?

What are your input and output settings?

Shutdown RealBand, rename RealBand.INI and RB.CFG then restart RealBand.

Info on 'factory reset' can be found in the faq's.

No feedback loops that I can detect, everything sounds normal.
I'm using a USB mixer as I always have into the PC, the only way I can get the System NT Kernel & System utilization to drop down is if I change the output audio driver to MME and uncheck the 'Output always on'.

I tried the factory reset method and that didn't do anything for me. I tested recording audio and playback and that worked fine

Update: after the factory reset on Realband, now it doesn't matter what I do with the audio drivers. Even setting it to MME with 'Output always on' unchecked does not get rid of the 25% utilization of System NT Kernel & System.

Update: This issue seems to be with my system and not with Realband. I tried some other audio playback sources on my PC and each one of them showed the same CPU utilization. Sorry to bother the forum with this, I had myself convinced it was due to the upgrade.

Rharv, You pointed me in the right direction concerning the audio driver. After 4 days of testing I finally figured out it was an audio driver from another piece of software called sound tap by NCH. The driver that was causing the problem is stdriverX64.sys I used ProcessHacker software to figure out which driver was causing the issue.

I uninstalled the Sound Tap software and now my CPU is running about 93% idle with Realband.exe taking about 5%.

Thanks also to VideoTrack for your suggestions, I appreciate the help!

All is well now in frozen North Dakota!

User Tip - Slowing Down and Looping Audio in Band-in-a-Box®

Forum user DeaconBlues09 created a video tutorial to help answer a fellow forum user's question:

Thanks for sharing!

#TBT - Band-in-a-Box® 2006 for Windows Ear Training Fun!

With the release of Band-in-a-Box® 2006 for Windows we added two great games for ear training: Pitch Invasion and Music Replay!

Pitch Invasion helps to develop perfect pitch as you shoot down "alien" notes invading from above (you hear the note sound, and click on the on-screen piano/MIDI or QWERTY keyboard to shoot them down).

Music Replay develops your pitch, rhythm, and melody recognition by replaying what the program plays, in note, rhythm, or melodic modes.

These games can still be accessed with newer versions of the program - in Band-in-a-Box® 2018 you'll find these by accessing the Practice Window or Ear Training Window, both located in the Window drop-down menu. The Practice Window can also be accessed using the Practice button within the main Band-in-a-Box screen (don't see it? CTRL+T to change the view).

Learn all about the features released with Version 2006 here.

Amazing Band-in-a-Box User Comments!

Great program with lots of support through the publisher and after-market. Use it for teaching, practicing, and gigging.
-Andrew L.

I just got my 6th film placement on a song recorded entirely in Band-in-a-Box. You guys rock!
-Terry Fernihough (Band-in-a-Box Endorsing Artist!)

I love this program. I have only had it for around a month but it has made things a lot easier for me. I no longer have to scour the internet for backing tracks. I just plug in the chords I want to use, find the style I want and done. Saving me so much time and being able to transpose into different keys is awesome too.
As the days go on I will be delving deeper into what it can do, importing some of my backing tracks into Abelton 9 to play with and writing some songs.
Best money I have spent on something in while.
-Peter S.

I started using Band-in-a-Box around 1990. It was the DOS version naturally and I used one of those old portable computers with dual floppy drives and a built in 9" monochrome display. I connected midi cables to a great sounding Yamaha keyboard and played my music using midi tracks. I did a demo for a university music class that was a lot of fun. Wow, it is almost unimaginable to see where this product has elevated to today. I have upgraded many times over the past 28 years but each time I am even more amazed. Thank you PG Music for being such a major part of my love for music all of these years!!!
-Dwayne G.

Incredible Software. Great for ignorance and experts and for anyone who wants to deal with music. If you do not have a hobby and want to have one "band in a box" is the best choice. Simple, but if you want to be an expert on it, you need to make an effort to master it perfectly for perfect use. The only disadvantage is if you do not want to become a musician, and use it, you will become a perfect musician. Therefore, be cautious. It's not a toy.
-Ilija B.

I’ve been using it for about the same time (20 years). I’m a trumpet player and just really want some backing on lead sheets. With the Real Styles - it sounds fantastic! Takes just minutes to input chord changes and find the right style. There is so much you can do and I love having the Soloist features to really add color.
-Mike B.
