It fixes the delay in Live 4 so everything is now in sync. The arp works flawlessly it appears with the few hours of testing I've been undertaking.There is one problem, the Virus is using 40% of the PC cpu in Live 4. This compares to 2% of PC cpu usage in Sonar 3, my other host. Not sure if the huge cpu usage in Live 4 is caused by the Virus or the way Live 4 works. The Virus runs on the Poco DSP so it shouldn't need virtually any PC cpu.
If anyone knows a fix then let me know. I've tried adjusting driver latency of my soundcard but to no effect. This occurs when using ASIO and WDM drivers. We're so close to a perfect Virus in Live 4 I hope this can be sorted soon.
