The problem with super low resolution waveforms, in my opinion, is

that they can be too buzzy with very limited control of harmonics.

They do have a nice gritty timbre, but too often can sound rather 

samey.  32 or more points might be better, but it's not as easy to 

control.  I guess waveforms that are some non-power-of-two 

number of points might have more interesting upper harmonics...



It's a nice think to work with, anyway, if you don't have to worry


about resampling or aliasing.



I found out recently that the RMI Harmonic Synthesizer used Walsh

functions to synthesize quasi-sinusoidal waves, the end result 

being a 32 point semi-arbitrary waveform with control over 16 

harmonics.  A modern version might be an interesting idea.
