certain stock instruments have a delay when playing back midi for the first note played

the only vsts that do this are all of the drumkits, and the new studio piano and strings. everything else seems to be fine. the issue is usually when i play right at the start of a note. the only solution i seem to have found it when dealing with the instruments listed is to move the playback thingy back a bar or so which usually fixes it. but if i dont do that it sounds all out of wack and its kinda annoying.

any more permanent solutions?
