Some latency probs here, please help

[Feonix]

Hey whats up everyone...Im using my Virus TI keyboard in FL Studio 7.0.2, however I'm having some latency issues. When i press a key on the TI it takes about a second for the sound to come up. So I changed my ASIO driver (from ASIO4ALL) to the Virus USB Asio Driver and my buffer length there is 256 samples (5ms). However...now no sound comes out at all...Under MIDI options I have put VIRUS TI MIDI at port 0 and VIRUS TI SYNTH at port 1...but back to the ASIO...my clock source is hardware..and i believe it should be external, but theres no option to do that!!! Can anybody please help me? This latency thing is causing my arps to jump crazily as well..please help..


thanks so much
