Everyone has seen the Google Doodle that hilariously failed at harmonizing like Bach.
Still the technology behind it is avalaible and demonstrated
here. Some of these apps are pretty "clever" !
Performance RNN is pretty cool and can input and output MIDI for live music generation !
Nsynth generates sounds that you'd have a hard time generating with a standard synth, especially when you combine an instrument with a natural sound.
Is someone going to try to make plugins that use Magenta for Reaper ? I can imagine so many possible uses, either for MIDI (melodic lines, drum beats, humanizer, etc), or for working on audio (an intelligent compressor for instance ?)
