Add file in Audio Plugin Juce

Hi , I am working on audio plugin in which audio file is added and keyboardcomponent will be used to play that audio? I am newbie and don’t know how to do that.

This attached post mentions the same scenario but i don’t get any way to hook up TransportAudioSource with ProcessBlock.

Maybe having a quick look at the AUv3Synth example (in JUCE/examples/AUv3Synth) which does something similar.

@fabian Thanks. It helped a lot.
