AKNodeRecorder allows you to record the output of a specific node.
Let's record a sawtooth solo.
Set up a source to be recorded
Pass our Oscillator thru a mixer. It fixes a problem with raw oscillator
nodes that can only be recorded once they passed thru an AKMixer.
Let's add some space to our oscillator
Create an AKAudioFile to record to:
We set a player to playback our "tape"
Mix our reverberated oscillator with our player, so we can listen to both.
Now we set an AKNodeRecorder to our oscillator. You can change the recorded
node to "reverb" if you prefer to record a "wet" oscillator...
