Hi guys,

Does anyone have any experience running libpd in an OS X app, using CoreAudio. 

I'm able to run a patch and receive print statements but I'm not getting any audio output and DSP doesn't seem to be processing. I created a quick test tone in code to see if it was my audio unit but that works. My main problem it seems is that after calling 

  [PdBase processFloatWithInputBuffer:leftBuffer outputBuffer:leftBuffer ticks:ticks];

...the buffer is still empty. Anyone have any ideas?

I'm calling [PdBase computeAudio:] just before I start the AudioUnit. Here's the whole controller class if that helps:http://pastebin.com/eYf1Facp

Any help would be much appreciated!

Many thanks,

Joe
