Hi,
Maybe you are using the ASIO Multimedia or the ASIO DirectX driver? Did you select the right ASIO device? If you didn't and have Cubase or Nuendo on your PC this is very likely to be your problem.
The latency is selected in the HDSP settings program.
Hi Johannes, many thanks for the motivation. I got it running now but the latency is
not
satisfying (30 ms) - with Max/MSP i have about 6 ms. Do you have better values?
I don't know the latency I use by heart, and I'm on a different machine. But it is more like 6ms than 30ms.
regards, Johannes

in the meantime i tried around and succeeded to get it running, even multi-channel. I'm using the native RME ASIO driver. It's very sensible, though. Playing around with the parameters (changing the buffer-size during operation etc.) occasionally resulted in bluescreens, which is normally rare under XP.

Yes and no... it's the I/O buffer size that you select... the portaudio library used by PD imposes some more latency.
I don't know the latency I use by heart, and I'm on a different machine.
But
it is more like 6ms than 30ms.
I measured it with the latency.pd patch provided with the newer pd versions. It gives me 33 ms at 48 kHz/256 samples buffer size.
greetings, Thomas

I've seen changing the buffersize resulting in crashes too. For the rest it appears stable to me.

I didn't know about this patch. Nice. I get 37ms at 44.1kHz and 28.6ms at 96kHz. I also use 256 sample buffers. I just "discovered" that the "-audiobuf" flag is used in ASIO too. I wrongly assumed it was only there for MME.

Thanks for pointing me to this patch.
