sorry for 2 topics, just forgot to post in the right subforum
thanks for the advices, well i managed to work it but in kinda weird way, every chanel i had to set on same delay compensasion as virus ti has.
About buffer size, there comes the problem, im using latency of 2048 samples so that the plugins could perform well, but if i play virus on that latency i get instantly "a sync error occurred". If i set the lowest latency (64 samples) so i just need to set same PDC on every chanel and virus works fine, BUT the plugins perform at least 2 times worse.
p.s. what is wrong with this forum, i cant see if i posted (it shows i didnt) besides i cant see my topics unless to see near my profile part (xx New Topics Posted or smnth like that)
