I installed today pure data PD-Extended (0.43.4) on a MacMini with OsX 10.7.5.
I'm trying to run some basic demos (Random Pitches) from the algorithmiccomposer.com website, but nothing exit from the internal loudspeakers.
Do anyone could help me?
Thanks

you can turn the audio processing on by hitting 'command' + '/'

turn off by 'command' + '.'

Thank you!
