Folder Arming causes lag in play

I just realized I didn't explain the problem.  When I toggle a folder with multiple instrument tracks, play back stumbles a split second.  Anyway to fix this?
 

Quad Core ADK
8 gigs Ram
Win 7 64bit
 
A couple of usb midi instruments.

I'm not using the onboard sound, have a soundcard.  Not a great one.  Creative Audigy I believe.

I have an M-audio fast track, can't wait to be rid of it and move to firewire.  I have to nudge everything left due to the lag.  But that is irrelevant for triggering MIDI instruments.

I mean, I've disarmed some of the play through buttons on almost all the instruments but one, but when I try to hit the play through on the folder it lags... nowhere else does arming the playthrough button cause a lag when I try and start using another synth.

I think I'll try using them as groups rather than folders and see if it isn't easier on the CPU.  I keep watching my CPU meter as well, and there is no real spike or glitch showing, or massive increase in Cpu useage.

Getting a firewire soundcard will not change things, most likely you'll see no difference compared to USB. If your PCs FW chipset is not by Texas Instruments, don't even bother, it won't work properly.

What drivers are you using? Which one of your soundcards are you actually using, M-Audio or Audigy? Use only one, preferably M-Audio., and take care that only that one is selected in Options-dialogue.

Your workflow and settins remain somewhat unclear to me so I don't dare to say much.

I've tried more stuff.  what I've found is if you have multiple soft synths assigned to a track folder and wish to toggle the input through button on the track folder so that the synths work as a group, they lag the project no matter where you are in it.  It's the same type of behavior that would happen if you try to add a soft synth to the rack while playing your project... same type of hiccup.  And yes I leave space at the beginning of projects.
 
I'm just curious if anyone else has seen this behavior?
 
I need to look at some of my tutorial videos and attempt to see if I can use them in groups rather than folders.
 
I will say this, very, very small problem that I think I will get around in some way or another.  But I think it would be a huge advantage if I can group all of my soft synth instrument tracks into folders and not have to input echo thru each one individualy when I would like them functioning as groups.
 
And I am running the 64bit version of producer.  I gotta say, most of it is quite smooth and very few problems.

got it, thank you
