Generator sequence

Generator sequence (AGS) is a scale-building procedure developed by Scott Dakota. AGS(x1, ..., xr) denotes a scale-building procedure where a scale is built by stacking x1 first, x2 second, ..., . When xr is stacked, we go back to x1 and start stacking x1 again, then x2, ...

Certain generator-offset scales are examples. For example, diasem is AGS(8/7, 7/6) or AGS(7/6, 8/7) depending on chirality. The trivial case AGS(x1) is stacking a single generator x1 to make a rank-2 scale, such as a MOS scale.
