Copy pasting my a reply to a similar question Short answer is yes! Previous work has shown that we can obtain very good results from controlling DDSP models from midi input. The solutions I am familiar with employ a two stage approach where the first stage takes midi and turns it into control signals (pitch & loudness contours etc..) and the second stage turns the controls signals into audio (like the particular model I discuss in the blog post)[1][2][3]. I actually think that the first stage could also benefit from the transfer learning techniques we discuss in the blogpost.
In terms of actually releasing a MIDI playable VST plugin I believe that Magenta have something like it in the works[4]. I hope that it will come with some ability for users to quickly create their own instruments, presumably using a transfer learning technique similar to the one we have presented. Real-time rendering poses multiple challenges. For one, some instrument sounds occur before a note properly onsets (for example the sound of the fingers pressing the keys of a saxophone occurs before the first note of the piece). Secondly, the research models are quite heavy and considerably more compute intensive than a standard VST instrument which poses a problem if you want to use it inside a DAW. I think this latter problem can be solved with some clever engineering and the general trend of hardware being more and more accommodating to machine learning applications.
