]]>Michael,
My netbook P.I is 10.Cheers,
Greg.
Thanks Greg, it's the same as mine then, not too shabby.

They do, Papi! 6 months ago, I bought my Tablet-PC Latitude XT2 via their French webpage, from section Petites et moyennes entreprises.
P.I.= 19
Yes what a shame, I didn't look in the PME side of dell.fr ! I saw it after during my search, I thought the prices where really attractive, until I realized I had to add the 20% TVA.
Anyway, I found a used Dell M1330 with a T9300, 4GB RAM and 320 GB HD at 7200 rpm which should do the work, so my search is ended. Thanks everybody for the help !

]]>It is HIGHLY unlikely that an audio interface sample rate of 96000 would be any better than 48000. Remember, Pianoteq is already limiting it's bandwidth to 24000/2 = 12kHz (the Nyquist rate, which you may have heard of) , so NOTHING we can do after Pianoteq can restore frequencies greater than 12kHz.
Without getting into the nitty gritty of sampling theory, it is TECHNICALLY possible for the fidelity to be better with Pianoteq generating audio at 24000, and then "up sampling" to 96000, than it would be for Pianoteq to be up sampling only to 48000Hz. It depends on how good Pianoteq is at performing sample rate conversion, and how good the audio interface is at filtering each sample rate to produce the analog output signal. I'd be a bit surprised if anyone could notice any difference, however. The main factor is the loss of bandwidth due to the rather low internal rate (24000Hz), and that's why I think it makes more sense to slosh less data around and use a lower interface rate. (btw, I realise that 24000Hz is not all that bad for piano sounds. It might be a bit different if Pianoteq ever models cymbals ;^)
I forget the P.I - I'll check next time I use it.

]]>Regarding the netbook settings, I'm also using Asio4All, and my performance index is usually 9-10. What's your PI?
Please correct me if I'm wrong, but I was under the impression that a higher sample rate for the audio interface, not Pianoteq's internal sample rate, would improve audio quality. Of course, for gigs the noise floor is so high that it wouldn't make much difference.

p.s. get out the candles and flashlight
]]>I was just using my netbook, with ear buds, and there was a thunder strike, and I received a small electric shock in my ears!!!
I was NOT running on battery power. Drats. I should have taken Michael's advice!!!!
Fortunately all my equipment (and my ears!) seems to be ok. I am typing this on battery power, and I have internet access due to my UPS. ;^) ;^) (power is out)

]]>48000/256 seems to work fine for me, and I can even bump the polyphony up to 64 it seems. (I watched the CPU graph in Pianoteq, and it never produced the red CPU spikes, and I never heard any clicks) My netook has exactly the same CPU & clock speed as yours. This is of course with Pianoteq's internal sample rate set to the same as you - 24000. Not too shabby, eh? I am using ASIO4ALL with the internal audio interface.
Unfortunately my audio interface doesn't support a sample rate of 24000 - I would have liked to have tried that too.

]]>what's the point in the "battery life"? I suppose neither your keyboard neither your PA system is running on battery anyway... or is it ???
Well, for me, I appreciate less wires and plugs, and my controller can be powered by USB also. This is for gigs mainly, but at home it's sometimes cool to have a keyboard setup, assuming headphones not an amp, that needs no AC. Especially during a thunderstorm
]]>Michael,
Is there any reason you chose 96000/512 instead of 48000/256?Thanks,
Greg.
Hey Greg,
It was a while ago, so I'm not entirely sure, but I think I was getting audio glitches with 256. If you like I can test it out.
Michael
]]>Thanks,
Greg.
Once it's set up, I close the lid and change settings/patches via my controller. The battery life is excellent, because the biggest drain on battery life is usually the display.
