Hello and Happy Holidays to all, For reference: Power Book G4, Logic Pro 6.4.1, MOTU 828 mkII interface. I am experiencing a continuous latency or delay in Logic. Never before Logic had given me this problem. I have the problem from about a week ago. This is causing me an annoying delay when playing. I have opened, for example, an instrument as a plug-in in Logic and also as a stand alone instrument out of Logic, and when I play the stand alone instrument there is no delay/latency, but when I play the instrument as a plug-in the latency is present. So I'm deducting that the problem is not the interface nor the MIDI cable nor the keyboard. Although I don't like to touch the default parameters, and my system has been running very well for about 3 years, maybe I changed a parameter in one of the Logic's menus but I don't remember this. Anyway, to which option and in which menu I should check to really see if I activated something by error? Thank you in advance.
