Hello everybody,
My name is Santiago, and I am an embedded software engineer. I have been playing around Pure Data for some time, and now I would like to further develop my skills on Music Design // Music Programming.
I am working with three versions of pd: Windows, Linux and Mac OSX. Currently, I am having a look at how to use several [adc~] and [dac~] (several input/output devices). In particularly I am doing some experiments using several external USB/FireWire sound cards.
So my question is if somebody knows if this feature (using multiple devices) is available on Mac OSX. I have been configuring it on a Windows machine (under Media > Audio Settings > Use Multiple Devices), where I can select i.e. three input devices and two output devices. This button (Use Multiple Devices) doesn't seem to appear in the Mac OSX version of Pure Data, despite of several input/output devices being available!
I have found some old threads dealing with this topic, but it doesn't seem to be a clear answer. Why is this option available in Windows and not in Mac OSX?
I have done some research by myself and get this thing working, but without luck. If somebody here comes up with a good answer, I will be very grateful. So I thank you all for your time.
Software Versions: I am using an "old" Intel Mac OS X 10.6.8 32-bit, and tried with pd vanilla (0.45.4, last version) and pd-extended (0.43.4, last version).
Hi Santiago -
Pd uses Portaudio to talk to CoreAudio. It loks like there's no reason one couldn't fix the code to offer multiple devices (although it still wouldn't work for Portaudio/ASIO because ASIO apparently doesn't permit it).
One reason I haven't done that is that Soundflower (if I understand correctly) does a decent job of it, probably better than I would be able to do, so I don't see an urgent need. (Also, allowing multiple devices complicates the code and can easily introduce problems; I've spent a lot of time fiddling with multiple-device support in ALSA and MMIO and have come to feel that it's an endless time sink.)
cheers Miller
2002 when multiple devices weren't allowed (as far as I know). Since
