i wonder if there's a place where i can read more about it - simply for the fact that i cannot understand how it would - but at the same time, i've never owned one

Maybe in the last moment, when I need to render the complete track I have to use usb for audio, right? why usb audio sound not good as analog audio? In theory if you use analog you have to do dual conversion, with the usb all remain in digital domain, right?

thanks for your time

please, can someone reply to this?
thanks!

If you understand nothing it's hard for someone here to teach you everything. Basically the TI can send sounds to the computer via the USB aswell as midi data, this mode is found when you run a vsti plugin from Access called the Virus Control. If you don't get into this mode your basically running the TI like a normal synth.

At the moment, as I understand it the headphone output is just a mirror of the OUTPUT 1 of the TI also the spdif out is the same. If you choose the TI as a sound card (ie audio playback in your software) you will hear your software outs through OUTPUT 1 along with any TI synth sounds.

You will not hear any sound that has it's output set to output2 in the head phones unless you route it through your studio / computer and back via Access Virus TI sound driver (ASIO or MME).

That will get you started.

If you want to play a part live with no perceptible latency, then you can set the output of that part to the main outs. When the part is being played back by the sequencer, you set it back to a usb out, so that the delay compensation works properly.

Me too Nutekk. Could you set us up with a link please?

Thanks Ben for your reply.
but, when " I set it back to a usb out" the sound is played back from virus main output or from an additional sound card?

From the Virus' main out, so you'll still hear it through the 'phones. If you don't set it back to usb, the sequencer still treats it the same as though it was, so it get's delay compensation when it doesn't need to. This results in it playing well ahead of the beat.

who said i have a link?
if you dont believe that some synths were designed poorly and had latency issues...then dont believe it.
i have extensive experiance with most of the classic synths
And through this experiance i have gained the knowledge.
as said the memorymoog(not sure if it was the original)
emu emulator2,roland d-70 was notorious,some obreheim synths suffered
there are plenty others..
why is this so hard to believe?
i doubt there is a magical link that has all this laid out
and has been stamped by a judge..for you to trust in.

As i said i have a sheet somewhere that has a bunch of popular synths with higher latencies...and there was a full page.
this info belonge to the synth tech that we would use to refurbish/and check out all the synths that we bought and sold.

i dont really care to prove it to you.
do your own research.

ahhh now I understand!!!!!!!
delay compensation anticipate USB tracks to cancel the latency so it's all in sync and I can play the keyboard (assegned directly to audio out) without latency!!!
If I understand right is fantastic!!!!

thanks Ben! :D

It's not that I don't beleive, it's just that I've never encountered anything like it.

I've played with a few boxes in my time as well. I get 5ms of latency with my software synths and I can definitely feel that latency when playing hard 'n' fast leads. I have never felt this on any hardware synths.

Fair enough....

As you sound like you have first hand knowledge, I have some questions for you to help my research:

1: When you were getting latency, was it occuring when playing from the onboard keyboard, or triggered from something else?
2: Were you triggering from a thru-daisy-chained config?
3: Were you using a PC/Mac sequencer running a USB midi interface?
4: Was the latency occuring when you were running many midi channels at the same time?

The research continues...... :D
