Hi, I am running Win7/64 and I have installed a new soundcard (Audiophile 192) because of latency problems with my old Soundblaster. I have also installed the free demo of Sonar Producer. In Cakewalk Pro 9, all my *.wrk files play fine with their original instrument allocation. Input from the keyboard, however, still suffers from unacceptable latency. In Sonar Producer, I have no latency issues with the keyboard and I have been able to create MIDI tracks using the instruments available in Sonar. When I load a *.wrk file, I can see the meters moving but I get no sound at all. My questions are - why was the latency issue under Cakewalk 9 not cured by the new and powerful sound card? - is it possible to gain access to Cakewalk's instruments in Sonar? Thank you very much for your help - I'll probably need more than the 30 days trial period to crack that myself :) Fritz
