Native ST4 only libs don't have any Patterns (essentially midi playback loops) so that's why installing just ST4 only libs wouldn't have any patterns to start a \Patterns folder.

Since I downloaded entire install and don't have the IK install media: the installs and sequence MIGHT be different? this won't help but:

1) I installed ST4 4.0.2 onto my D drive (D:\Music\IK MultiMedia\)

2) Installed just each ST4 Lib into D:\Music\IK libs\ST4 libs.

Since everything else had previously been installed D:\Music\IK libs\ST3 libs (all the add-ins and add-ons mainly from total studio 2 Max) I did NOT “re-install” them.

3) Then open ST4 application had it scan the sound folder "D:\Music\IK libs\ST4 libs" - it was all there I tested a few ST4 sounds in each category to make sure.

4) finally I added the ST3 sound path and had ST4 re-scan to add all my other sounds that are installed under the ST3 sound folders


Suggestion: Maybe uninstall ST4, clean out any lingering folders then start over. I'd also get on the IK forums and read how others had issues and resolved them, if still have issues - CONTACT IK Support


Good Luck
