Great question! I think this approach (and DDSP more generally) could work well for most instruments if you make some adjustments to the synthesis architecture.

The current architecture imposes some strong assumptions on the source (such as harmonicity) which does not necessarily apply to all instruments (bells for instance). The harmonic + noise model is not that good with transients either (which is a key ingredient in piano sounds) but of course you could solve that through different means.
