Yet, if you simply don't have any of these libraries, it may help a bit to use the LFOs or whatever to add a bit of modulation. To raymond: >> I've try out the LFO routering ..but still can't get a very strong >> Vibrato >> feel...what to do on it?? What exactly are you doing? Putting aside how natural (or unnatural, for the matter...) LFOs will sound on natural string material, I can get the most strongest vibratos and tremolos imaginable from the LFOs. Do you want me to post a little sample patch, using one of the instruments coming with Logic? Regards Sascha
