View Full Version : Headphone routing in the TI

I need to know if this is possible:

Headphone monitor (on the TI) the TI asio feed from the sequencer but not the virus parts that are playing via the analog outs.

The quality in the DA is awsome in the headphone, a tad more detailed than the RME Fireface 800, and that's saying something.

Same goes for the spdif, is it just a sum of everything, or output 1?

My wish is that these routings become user controlable.

big call. i dont have my TI yet but if you are telling me it is of that sort of quality then it will certainly have been worth the wait.....

if only next week were here already... ;)

Would this mean then that the analog outs sound even better than the audio going out of the USB(because the quality is already very impressive)?

correct me if im wrong here, but i think the usb is on capable of 44.1/48k sampling rates, where as the analog outs push out 192k - no?

and ONLY 16BITS!!!

and ONLY 16BITS!!!

lets hope that change with future OS updates - but I honestly cant see it happening...

the internal resolution is much higher. furthermore you can use the Virus Control it in 24bit projects, no problem, the Virus Control converts the signal for you.
see, when you sum up signals, this is where you need the extra bits because you want full dynamics and no clipping. the virus sends submixes to the virus control and -at least to my ears- i cannot hear a difference to the 24 bit signal, the D/As get.

you can check this yourself - setup the TI as you audio interface and compare the quality of a signal piped through USB into your sequencer and back again to what you get from selecting the analog outs directly. i personally don't hear a difference but i would be interested in your opinion.

well, nowmally, you hardly hear the difference between 24 and 16bits, but when you add some compressors and effects and so on, there'll be a difference. further, the TI could have dithered the sound going out through USB, so you don't really hear the difference, but it's there...

btw. the Virus TI uses 56bits internally, that's at least what access told me

exactly. once you touch the signal, by adding effects or for instance by summing a couple of signals, you might here a difference. that's exactly what i mean.

the headphone outs on every keyboard i've had, have always sounded better than the analog outs. the headphone out also seems to have a higher volume.
maybe manufacturers do this for when people audition them before buying?

It'll be because a lot of decent headphones take a hell of a lot of driving - my Sennheiser HD650's are barely audible via my Denon mini hifi, and my old pair (430's) are even harder. The TI drives them both no problem.

One thing i noticed between the 1st and 3rd virus kc i had was that the headphone output was a bit hotter....and alot less noise. A welcome improvement even back then (circa feb 2003)

My comparrison in sound between the Virus headphone out and the RME headphone out was just for music played over the audio driver, no virus sounds or anything.

-edit-
Using the Asio driver for the TI at 32bit (max freq 48khz).
Slightly deeper bottom - had to realy feel the difference.
Tad less digi tops - like a bee's d#%$ difference.

Using the WDM driver for the TI 16bit max (up to freq 192khz)
Sounds slightly inferior at any sampling rate.
No detailed image.

Setup using Wavelab to play back audio files (16bit and 24bit files).
Using Voxengo Recorder plug to live stream 32bit to RME Fireface.
Hot plugging headphone outs to JVC Hybrid Amp and Akesis Monitor Ones.

Dont think so - I think the TI allwas operates at either 44.1 or 48 internally, they jus happen to use very high quality DACs that are capable of 192KHz, but arnt actually used at that rate.

I must admit - from their marketting blurb, I got the impression the internal sample rate was 192KHz.

Ive since heard its only 44.1K or 48K, in which case I am surprised as the TI filters sound alot smoother than I would have expected at that sampling rate.

I would be interested to know what the internal sample rate in the DSPs actuall is - just curious :)

I've already asket the internal bit resolution (56bits). Now, it's someone else's turn ^^
