virus TI internal specs
 
I've contacted Access concerning the internal specs. On one hand, the support assistant told me that the internal bit resolution is 56bits, but on the other hand, he didn't want to tell me the internal sampling rate...

To me 56bits is stunning, so that might be the reason why he told me this. Is the sampling rate exaxt the opposite? 40'000 (there should be some aliasing in the higher notes according to some reviewers, I had no chance yet to have a look/an ear to it, there's no single virus available in the shops at the moment)?

So its internal resolution is 56bits and it outputs 24/192 through the analog outs. That sounds good!

I think the "192Khz DAC" jst refers to the specification of the DAC part and says nothing of the actual sample rate it is run at.

The internal processing rate may also have nothing to do with the rate at which the DAC is fed (just to add to the fun) because the DAC feed rate *appears* to be tied to the USB sample rate - ie 44.1 or 48, or mabe some multiple (88.2/96 etc).

All the previous virus models have worked at 44.1 or 48kHz. And if the TI's usb connection works at that rate I guess they still use it. And Access is known of programming efficient code (the B-series for example had the reverb later and more polyphony if I remember right) and not use too much dsp power so running things at 96kHz is not their style, I guess. :wink:

How do you want to know that since Access don't give any informations?

Is there a tech expert who knows Motorola processors? What sampling rate does the 56bit processor model *support*?

If you mean, how do I know? I got an answer for this from access support a few moths ago when I was asking the sampling rate of the virus ti.

Yes, that's actually what I mean. In German, you ask it that way I've done first.

the internal SR must even be bader than 44kHz, there's an immense aliasing on the upper notes... horrible

Correct me if I'm wrong but isn't it related to the fact that this is a VA and the OSC waveform arent multisampled accross the whole range?

I don't think the internal samplerate would be less than 44.1 but my guess would be that it is 48 since for some reason my TI(im not alone) ALWAYS resets to that samplerate.

area they sampled at all? I hope not
