Very nice work. This could be used to efficiently re-implement 8-bit- and 16-bit-era sound systems, which are mostly emulated on the CPU at present. I wonder if the same techniques can also be used to enable DSP-like workloads of a more general sort on GPU compute.

Most of those are either very straightforward subtractive synthesizers, or use digital FM synthesis. It's much more efficient (and accurate) to start from sampled basic waveforms or reverse-engineered data from the actual systems, rather than building them using additive synthesis techniques.
