Seasons greetings! background: I'm a Mac guy who is using windows 7 for the first time to gain access to some old Logic 5 projects where I need use of the mk I EXS24 sampler. After installing Logic 5, I plugged an Akai LPK25 USB midi controller into my toshiba PC and the midi latency is pretty soggy. I really don't know much about PC's and how people refine a useful midi connection for use with usb midi controllers. I did, of course, install the driver for the LPK25 so that the device would be recognized in the first place. How would the other half (pc users) deal with such a situation? Are there some standard/universal midi drivers that would do the trick? Some inventive Logic settings tinkering? Thanks for your time and attention! Also, where would I go to locate the version of Windows 7 that came preintalled on my PC? Thanks so much!
