Hi. I'm attempting to build a basic multitrack program using MixerAudioSource.
I have 3 wav files being loaded into separate AudioFormatReader -> AudioFormatReaderSource -> AudioTransportSource.
I'm using MixerAudioSource.addInputSource() 3 times to add each of the TransportSources and then setting the MixerAudioSource as the source of an AudioSourcePlayer.
When I add this AudioSourcePlayer as the audio callback to the AudioDeviceManager, it hangs.
In the juce_BufferingAudioSource's prepareToPlay() function, the while loop at the bottom runs endlessly because bufferValidEnd is always 0.
If I only add 2 tracks, it works perfectly. Adding the 3rd track causes the endless loop.
Can anyone point me in the direction of what I'm doing wrong?
** FIXED: I had separate threads on the TransportSources and once I removed them, it worked. BTW, any suggestions on how to optimize this approach would be appreciated...
