Hello there!
So i’m new to openframeworks and have been playing around with Maximilian, building my own synth in the testproject that Mick has provided with the addon. Which worked fine and I’ve heard lots of interesting sounds!
However now i’ve come to building it as my own project i am no longer getting any sound (even with just the sine solitary oscillating sine wave), it compiles fine but no sound and I don’t know why 
Can anyone help? I feel this is probably just a really dumb mistake or overlook by me but I’ve been staring at it for too long, and could use a clip round the back of the head…
Other part of the app will use ofxCV (which I have working in a separate file, but for now I would really like the audio working…
Any help would be greatly appreciated.
