Do the Sound blocks work on the iPad?
sound on iOS is still an unresolved issue. I can get microphone samples and video, but it's so far resisting sound playback.
Hey, interesting thing, I have actually gotten (gravel road driveway type beat level) rough audio playback from my microphone using the Play Frequency block, A list, and a script that adds the freq of the microphone at that current time to the list.
