This sounds very interesting.

Would there possibly be a way to compile pd to use Steinberg's ReWire system? This would allow us to use it directly with sequencers like Cubase, Nuendo, and Reason in WinNT and Mac.

Thanks for all the hard work. I think many of us would be very interested to see it. Chris

This is brilliant!!!!!! Will you publish your version? (I am afraid I don't have MSVC) I would appreciate it. Bravo, Michael

I compiled an ASIO version of PD using PortAudio v1.7 with the beta ASIO drivers and Steinberg's ASIO 2.0 SDK. The program compiled successfully using s_mac.c and s_portaudio.c with MSVC++ 6.0.

Both audio input and output are working as tested on a DIGIGRAM VxPocket v2.0 PCMCIA audio card running on a Sony Vaio under win2k with the latest driver package from Digigram (v4.4c). I tested it with a microphone and monitor speakers.

The software reports 12ms latency for each device: i.e. 24ms I/O latency. This corresponds with what I heard and is a significant improvement over the ~350ms latency reported when using the Microsoft Wave or DirectX drivers.

Here's the PortAudio startup report:

P:\pd\bin>pd MIDI: not yet implemented read/write PaASIO_QueryDeviceInfo: numDrivers = 1 PaASIO_QueryDeviceInfo: InputChannels = 2 PaASIO_QueryDeviceInfo: OutputChannels = 2 PortAudio : possible sample rate = 32000 PortAudio : possible sample rate = 44100 PortAudio : possible sample rate = 48000

---

PortAudio : minSize = 504 PortAudio : preferredSize = 512 PortAudio : maxSize = 2016 PortAudio : granularity = 126 PortAudio : User buffer size = 128 PortAudio : ASIO buffer size = 512 PortAudio : Minimum BufferOffset for Output = 0 PortAudio : ASIOCreateBuffers with size = 512 PortAudio : InputLatency = 572 latency = 12 msec PortAudio : OuputLatency = 572 latency = 12 msec

To do: create a new file called s_nt_asio.c that includes the NT MIDI interfaces as well as the PortAudio calls from s_mac.c. Has someone done this already ? If not, I'll try and make it.

Hi all,

There's a Pd "portaudio" interface (in s_mac.c and s_portaudio.c), and portaudio supports ASIO in "beta"... see http://www.portaudio.com/

So in principle you can get Pd to talk to ASIO by just linking it all toghether. I haven't tried this because I don't have any soundcards in my Windows machine that support ASIO.
