Hello evryone!! Not sure if i reached the right place.
Specs:
OS: Win XP
Processor: P4
RAM: 2GB
Sound card & Midi Controller: Line 6 KB37
Recording: Nuendo 3 and Sonar 6
I bought this Line 6 KB37(works as a MIDI controller and sound card!). All functions are working fine. Recording guitar, bass and vocals are perfect. But when i try triggering midi notes from vst plug ins(Reason etc) through the KB37, theres lot of latency(both in inputs and outputs) and it keeps increasing gradually after further recording. i dnt knw if this happens after recording(including) more wave tracks(guitars, bass etc) or just a while after use of the PC.
Can someone please help me out on this? Its new and, not being able to use it fully is driving me nuts.

Jun 23, 2008 07:24 pm Hey there, welcome to HRC..
Ya, the track load can cause the latency to increase a little at a time.
You might want to try lowering you buffer in the Line 6 control panel.
Also the first thing I should have asked is if you are running it with the ASIO drivers or the WDM KS drivers?
It sounds like you might be running it with the WDM drivers.
But either way, try switching it to ASIO and then make sure the buffer is set to 128 and give that a try.
My UX-2 can get down to 0.8 ms of latency with the buffer set at 128 so you should get close. You don't say the speed of the processor but mine is 3.2 gig with 4 gig of ram and that is what my system will run flat without over clocking.

Jun 24, 2008 08:19 am I dnt presume its the track load, because i hav used a lot more than wht i did last.
Point is, even if i use just one midi track and nothing else the latency keeps up.
I'm using ASIO. and procesr is 2.4
input latency is 14.x ms
and output is 29.x ms
Is it some setting in Nuendo that need to be changed?
Jun 24, 2008 08:24 am I have noticed latency in a few USB powered MIDI controllers if they are running on USB power, when I plug them in to a wall plugin and not rely on the USB power the latency often goes away.
It's weird, but I have seen it on at least 3 controllers...I have the KB37, but it's been so long since I have used it I can't even remember if it has optional wall plugs...

It doesn't and I have seen the problem in other USB Midi controller units, even the more high end ones (well as high end as USB controllers get). I don't that at the moment there is a way around it unless you really tailor your computer to receive those incoming signals. My friend who does alot of midi work just has to shift everything back into place after playing...

Jun 30, 2008 03:09 am great guys thnks. i'll try the wall plugin
for the time being i re installed XP and the drivers so the latency is just fine. i'v got just two problems now.
1. the ASIO KB 37 control panel doesnt show up
2. in sonar, there's latency in start and stop play. otherwise recording is fine
Thnks great

Jun 30, 2008 07:09 pm You should be able to open the control panel from start/program/Line 6. Then it should show you Gearbox and the panel. If not you might be able to open the control panel from Gearbox itself.
I know in Sonar 7 PE I can open the panel by clicking the ASIO panel. Not sure if that functionality worked perfectly in other versions. I know in 5 and 6 I had trouble. But it was not on Sonar it was the way Line 6 wrote the driver. It wasn't faulty to say, but it didn't respond to certain commands from some DAW's. It is now fixed and Cakewalk actually made it easier to access even if it is the older version of the Line 6 driver.

Jul 04, 2008 04:21 pm Well the Line 6 install is broken down wo you can install as components. Are you making sure it is installing the Gearbox software and the related pluggins?
It sound like it is missing that when you are installing.
This is what I did on my newest set up. I didn't bother with the install disc at all. I simply went to the Line 6 website and downloaded the complete current version of the driver install and gearbox package. It should be at the top of the list if you select the kb37 and follow the prompts in the download section.

Jul 05, 2008 12:47 am i dnt hav the proper driver cd. i downloaded it from the line 6 website. and whn it prompts for all components, i uncheck all and just choose KB 37. could tht be the cause? should i choose all? cause previously i DID choose all.
1 more question, i'm goin to get the orginal driver cd today. does tht come with a free gear box installer? cause the ones from the website are not!
thnks again. u guys rock

Jul 05, 2008 12:52 am Yes, the complete install comes with the free Gearbox install. The pay for ones are the VST pluggin for use in a DAW such as Sonar or Cubase.
And ya, un-checking everything you probably unchecked the gearbox installer.

Jul 07, 2008 02:16 am alright. i'v re installed the driver, this time with all components checked and voila the line 6 control panel shows up.
but the latency thingy is bck and this time its worse. so whts happeng now is tht, when i run the drivers with just KB 37 checked, the latency is fine, but the control panel is missing and when i run the driver with all components checked the control panel shows, but the latency is all over
Help help. there's no driver cd. didnt get it. could tht be the cause. not running the original driver cd. i downloaded it from the website. a friend of mine has KB 37, so if i get his driver cd(original one), is it going to help.

Jul 07, 2008 10:03 pm No, the download package will be much more current then the CD, even if you buy it brand new in the store the CD will still be out of date.
I'm confused by what you mean by all components checked????? Can you take a screen shot and post it so I can see exactly what you are talking about?
And when you say control panel, are you talking about Gearbox of the ASIO control panel?

Jul 11, 2008 03:43 am ok guys the screen shots
=all components during set up
=line 6 KB 37 ASIO control panel
when i choose all components during the set up, i can open the control panel. in this case, the communication between the midi trigger(KB 37) and my DAW(nuendo) isnt correct. when i play using a VST, the playback is fine. but when i start recording, it doesnt play correctly. the notes come in late and they'r not the correct length. all this happens when i choose all components during set up and the control panel shows.
But during the set up, when i choose just KB 37 in the 'choose components', recording and playback are just fine. but the ASIO control panel is missing. it doesnt show up when i click for it.
Cause of this i cant change inputs on the control panel when i need to change from audio in to mic in.
i hope i made it clear enough for u guys to understand.
thnks

Jul 11, 2008 08:38 pm Well, on the first picture you had all the drivers checked to install for every Line 6 device there is. You only want to have the DB37 checked and have it install Gearbox and Line 6 Monkey.
Do you have Gearbox installed at all?
Also, did you install the Line 6 Monkey? If not you need to do that and let it check for the current updates and and firmware for the device. It sounds like you do not have everything installed or current.
Also, where exactly are you clicking to check for the ASIO control panel?
I am thinking that part of the problem may be in Nuendo as well.

Jul 15, 2008 12:17 am This time, i checked only the KB 37 box while installing. and then i also installed gearbox. but the problem still persists. i also tried installing an older version of line 6 driver. but the effect was the same. playing VSTs during playback is fine. but when i record, its not at all accurate and then some of the notes are much much longer than i played em and totally out of sync. i need to pull or push em back in place manually after playing. and its not by little. the notes are just off time.
i dont hav internet at home(i soon will though). so i got the CPU and the KB37 to work, installed Line 6 Monkey and updated the drivers. before doing that, there used to be a prompt saying the firmware needs to be updated. after updating with Monkey and running a subsequent check, it prompted that the device was ready for use. the problem was still there even after that. so then i re installed Win XP. and the problem is still there. this second time round however i havnt used Monkey. but th since thts just an updater, i dont think it should cause a problem.
About the ASIO control panel, i think that is solved now. after re installing the line 6 KB37 driver, its showing up now; wherever it has to.
But the midi recording inaccuracy... i just dont understand why god is treating me this way...:-) thats the only problem now. apart from that all's fine.

Jul 16, 2008 10:24 pm OK, there has to be a setting in the recording software that is gone astray. I'll assume that when playing guitar or the like through the thing it is on. It is simply the midi data with the VSTi's that is going out? There has to be something not set proper. I use the UX-2 with Sonar 7 PE and don't have any problems like that at all with VSTi playback. Granted I am using a different midi interface and normally use a different audio interface, but the UX seems to be working flawlessly although it does not have the midi keyboard on it.
I'm thinking it may be time to contact Line 6 tech support on this one. They are pretty easy to deal with via email.

Jul 17, 2008 12:22 am oh great.... i guess i'll try em out. but u'v been great man.
also i'v been told tht whts happening is called a 'stuck note'. does tht by any chance tell u something.
Thnks man

Jul 19, 2008 03:27 pm I am wondering if there is something conflicting in the system with the midi drivers themselves then. And ya, stuck notes used to be very common. It was usually caused by the hardware streaming too much data for windows or the software to keep up with.
If you know how to go into windows device manager do so and take a look there for any USB conflicts that might appear. Check all the tabs for any USB devices along with their drivers and such.
