i didn’t know unity3d features low-level audio processing. after reading this, however, i was delighted to see it actually seems quite possible to work on, in fact, the engine provides some cool additions when combined with its existing dsp components and all. so, why not give it a try. i have built a simple – one octave – mono synthesizer to see how it works out.
and here’s the result. asdfghjkl are for the white notes, wetyuo are for the black notes; just as are in any daw. cheers.
