«Re: sloth canons [Pattern Extension]» by tom.dugovic

Save this as an extension and recompile class library. You can now use Psloth([0,1,0], 10), for example, instead of declaring a new routine for each pattern.

I didn't persist the use cases, as this should be saved as a .sc file. Please refer to the ancestor code for usage.

Memory/CPU usage will grow over time, but at a decreasing rate. This can be used for a large amount of repeats. Extensive testing has not been done on this though.
