Toneport KB 37 Latency Solution using Music Creator 5. This might help.

 If you are trying to use a Toneport KB37 or Port Studio 37 Line 6 Product and Music Creator 5 and keep having Latency problems I thought I would offer a few suggestions that might help outside the norm, since we are talking about a specific product.

I myself hadn't started using the keyboard function of my Tone port Kb37 until now. But it should apply to the Port Studio Kb37 also.

I tried every buffer change you could think of with trying to record using the keyboard function of the Toneport KB37 with Music Creator 5, and the Latency issues just kept happening, even though my computer system far exceeded the specifications for MC5. There was still Latency. And I should mention I had the latest drivers for my Tone Port Line 6 Kb37 product, and windows.

To make a long story short. After changing the Line 6 buffers device settings - "Which all depends on your system's abilities", and after changing the buffers in Music Creator 5 - "Which all depends on your system abilities also", I finally figured out a setting that worked using my keyboard on the Tone Port Kb37 and Music Creator 5. The setting was in "Options/Global/Midi", I had to change PLAYBACK to 100 instead of 500. 

 Before I done that with my Single CPU computer I got latency to the point using the keyboard function of the Tone port KB37 and Music Creator 5 was not an option.

I have a single processor computer, so that number might not apply to others out there having a problem. "BUFFERS" was not all of my problem because I tried changing them to every setting you could imagine before I found that one setting in MC5.

I wanted to mention this because, if you search the internet you wont find this information posted, or at least I didn't so I thought I would post it.

Keep in mind,  that setting isn't written in stone, same as your Line 6 Tone port KB37 buffers. Or Port Studio Settings.  Buffers could be your whole problem depending on your computer. It wasn't the whole problem with mine.

The things is, I had ZERO problems recording guitars/bass/vocals with MC5 and the Toneport KB37. It was only when I decided I wanted to use the keyboard that I started having a latency problem trying to use the keyboard. From what I understand the new "POD STUDIO KB37" isn't any different from the Tone port Kb 37 so it will probably have the same problem". I think the software packages they offer and the new name is the only difference. I can't say for sure though. 

I hope this helps someone, or gives someone a idea that might help them. That's the entire purpose of me posting this. Even asked line 6 about this, and until I figured out that was the problem they were still trying to help me. They have a great support group in my opinion.

This is what worked for me.

Good luck to you all out there in Cyber World!

 I decided the other day that I wanna learn to play the keyboard a little more. I have just been using it as background noise you might say in the past, single note stuff so I never paid much attention to the latency on the keyboard until now.

I read about that PLAYBACK selection in the docs the other day, but I thought it only pertained to playing back the pre-recorded midi and not to recording it.

The freeze track button on the track view in MC5 has really made things easier for me. I know I could do it in MC4, but it got old doing it from the menu selection. If I use a lot of VST's I still get latency with the keyboard unless I freeze the tracks first.

This brings me to a question, freezed tracks are just tracks that have the effects applied to them, or are mixed down temporarily on the track to free up memory and cpu usage right?  

If that's the case, I've done 3 songs using MC5, and when I mixed down the songs I haven't unfroze the tracks. Is that the right thing to do? Or should I unfreeze them before mixing down, or does it make a difference?

 If I unfreeze them I can't play the song first before mixing it down because I don't have the CPU power.

I guess what I am trying to ask is, if I unfreeze the track, are the results of the mixdowned song going to remain the same or differ in volume or quality?

What I'm thinking is, if I unfreeze the track and mixdown the song even though I can't hear it before mixing down, the mixdowned song is going to sound better because it's not going to be mixing down compressed tracks. I'm guessing here.

The reason I ask if it's the right thing to do by leaving the tracks froze is because mixing down unfroze tracks would involve a lot of guess work and reloads and multiple mixdowns blindly. But then again, if the sound quality is going to make a big difference then I guess that would be worth the time. I dunno.

I think I'll stick with freezing them, but in the future I'm going to pay more attention to the solo track feature and use the eq. Freeze the track, solo it and listen to it, unfreeze it and mix it one track at a time before the final mixdown.

LOL, I think I just answered my own question. :-)
