Hi,
I've just noticed that using a ULLI setting of 3ms gives 6ms total Output latency in Cubase. Nothing really, but strange as my other system doesn't have this, 3m gives 3ms out.
Anyone else have this?
Cheers

3ms in is 3ms latency. 3ms out is 3ms latency.
an xtc plugin would be 3ms out of cubase + 3ms in to cubase out of the Scope card(latency is the calculation time alloted to the cpu. Scope processing is external to the PC's cpu) = 6ms total latency.
yes, i've seen that. likewise for the external effect plugin. it's correct. likewise for midi to audio in a VST instument. 6ms is the equivelent of the latency of sound from a guitar player's amp 6 feet from him. 20ms latency is even manageable. more than that starts getting kinda crazy...

Like garyb said this is ok.

Cheers chaps,
As I said, no problem. I never noticed any differrence in playing/recording between my to computers.
Thanx again.

Re: Cubase SX3: Total Output Latency?
To give some "insights" about this latency symptom:
Under XTC,, the latency is .... 6 time the buffer size.
Why is the latency of in and out 2 times the buffer size??
Because cubase write 32 bits floating points which have to be converted to 24 bits ASIO before to be written to the DSP hardware.
After the buffer switch callbak execution, the ASIO driver is responsible for converting the DAW data to 24 bits and it deliver the buffer to the hardware after the next buffer switch callbak execution.
cheers
