Ahhhhh, thank you!

I think I only just now realized that we need to assign those based on where they're GOING not where they come FROM. Of course! lol

This does work thanks:

```haskell
fast (range 1 2 $ cT 1 "20")

```

But what if I do want the results to be an integer (ie either 1 or 2). I would think that I'd want to use `floor` or `round` but I'm getting errors from:

```haskell
fast (round <$> range 1 2 $ cT 1 "20")

```

Any ideas?

'quantise 1' is the easiest way I'd say [Alteration | Tidal Cycles](https://tidalcycles.org/docs/patternlib/tour/alteration/#quantise)
