Johannes,
Perhaps the current output buffer is emptying before PD can fill the next buffer, this might be causing the broken sound.
Yes, that'll be the problem. I recorded some output of pd digitally, and I can confirm endianess is not a problem. My previous remark about stability was based on the assumption that it was an endianess-problem.
To fix, try increasing the buffer size...
Right, that helps in some cases.
This parameter will be dependent on the specific sound card. (126) works for a digigram VX pocket because that's the buffer granularity. Such low latencies work with simple patches, for more computationally intensive patches (252 / 256) or (504 / 512) are necessary.
I guess this 126-samples buffer is specific for the vxPocket?
What I notice that on one PC the ASIO direct sound driver warns that it cannot do full-duplex, and the ASIO multimedia configuration test dialog pops up, when I start PD.
I'm afraid pd-asio is not using the native asio driver, but the directsound or mme wrapper. Where can I change this?
Do you get it to work stable on your vxPocket?
thanks, Johannes
