## Evaluation
The Strudel REPL does not support [block based evaluation](https://github.com/tidalcycles/strudel/issues/34) yet.
You can use the following "workaround" to create multiple patterns that can be turned on and off:
You can use labeled statements and `_` to mute:
```
let a = note("c a f e")
<MiniRepl
client:visible
tune={`$: n("[0 .. 8]*8/9").scale("C:minor:pentatonic")
let b = s("bd sd")
stack(
a,
// b
)
```
Alternatively, you could write everything as one `stack` and use `.hush()` to silence a pattern:
```
stack(
note("c a f e"),
s("bd sd").hush()
)
```
Note that strudel will always use the last statement in your code as the pattern for querying

The 3 parts (drums, bassline, chords) are exactly as earlier, just stacked together, separated by comma.
