Johannes,
thanks for the feedback. this is very important for me, because I do not have a HDSP card. I will address the 512 blicksize issue soon, this will improve latency figures (Should improve the behaviour of pd/ALSA in general, at least that is what I hope for).
Will post updates to the list.
Great. I'm ready to test further updates.
Could you please also adress the 96kHz issue? I really need 96kHz for ultrasound motion capture...
To use PD+ASIO+win2k+HDSP at 96kHz, I have to trick my soundcard by opening the MME driver at 96kHz in another application while starting PD. Otherwise portaudio/asio seems confused by the different number of channels at different samplerates. Sounds like a similar problem is happening in alsa. Also this message appears in dmesg:
ALSA ../../alsa-kernel/pci/rme9652/hdsp.c:698: cannot change between single- and double-speed mode (capture PID = 651, playback PID = 651)
Now on to getting my midiman usb midisport 4x4 to work past its first port...
