Error Creating Input BUffer

dj-gutz · Jun 27, 2009, 06:15 PM

hi all

im experiencing a little problem here and hope you can help me

what im trying to do is to use ART Tekninka console as my dsp ( because its much more flexible than kx dsp )
info : console sound modular studio : Host for VST Plugins & DirectX(DX) | How to use | Buying | Useful Information

im using this in my car-pc setup for 3 way active + sub ( 7 channels )
with pci audigy 2 zs ( sb0350 ) , kx 3545b , windows xp pro sp3

so basically what im doing is recording to asio from fxbus(0/1)
then output from console through asio to the other fxbus's
then fxbus 2/3 , 4/5 , 6/7 , 8/9 is connected to kxlt

now my problem is im getting an error when i try to achieve high latency ( to avoid stuttering and such )

in 16/48 with 8+8 i can get up to 85ms
in 16/48 with 16+16 my max is 20ms

after those values i get an error that looks something like this :

Code:

Error creating input buffer #2 : error = -10 ( size = 32768 )
GetLastError() = 2
 
Uknown Error 
 
Retry?

from what ive read its due to high latency , anyway to fix this?
and if someone can explain why its happening? from what i know achiving lower latency can cause problems and glitches but why is there limit on max latency?

i think i can handle with the 85ms ( altough i think ill need more but for now its ok ) , but im limited to 6 channels and i need 7
i searched this forum and found out that you can remap cubase to use the first 2 asio out's - anyone knows if thats possible in console?

if this can't be done with kxasio , do i have to use asio4all drivers?
will it hurt my sound quality ?

edit :
forgot to mention that hardware accel set to full and the other slider set to best

thanks in advance ,

Higher bit depths, higher latencies, and more channels require a larger buffer size. kX has a max input buffer size of something like 32,768 bytes, so the maximum possible latency will depend on the chosen bit depth and the number of channels.

See the following post (#50): 3545 released (BETA) - revision 3545b

Note that the above is related to the recording buffers (i.e. the error is about the input buffer), I am not completely sure how the playback buffers work.

i.e.
Recording 2 channels at 16/48, the maximum possible latency would seem to be @85.33 ms, which is in line with the results you are getting.

Using the 16/48 [16+16] format, you should have 14 usable outputs (not including FxBus 0/1... as you are using it for recording).

That should be the same for both (assuming the same number of recording channels)... Make sure that you have the same number of inputs enabled under both settings (from the above results, it seems that you have 2 channels enabled when using the [8+8] setting, but 8 channels enabled when using the [16+16] setting).

thanks russ
i did some experiments
used only 2 channels for input ( when i wrote the post i forgot to disable the rest and thats why i couldn't get past 10ms )
now i can get 85ms which is ok i think

the wierd part is that in my home pc i have sblive 5.1 sb0222
and i can get 170ms

does the 10k1 chip has larger buffer than 10k2?

thanks again russ

Yeah, the buffer usage is different with 10k1 models. I assume this has to do with bit accurate recording/playback (which 10k1 models cannot do).

i.e.
The new model implemented when 24 bit support was added, uses two lines instead of one (thus buffer usage would be doubled).
