Hi, first time trying Tidal and this showed up:  
• Couldn't match expected type ‘IO () -\> Pattern ControlMap’  
with actual type ‘Pattern ControlMap’  
• The function ‘sound’ is applied to two arguments,  
but its type ‘Pattern String -\> Pattern ControlMap’ has only one  
In the second argument of ‘($)’, namely ‘sound "bd" hush’  
In the expression: d1 $ sound "bd" hush  
I read some similar old thread, but the solution proposed did not work for my OS (mac high sierra). Supercollider working fine.  
What can I do?  
Thanks

Hello @marcelo.arcos2 and welcome to TidalClub!

It looks like you have `hush` in the same line as `d1 $ sound "bd"`.  
Both must simply be in separate lines and then it should work.

Hi Thomas, and thank you. Hope you and your family are in good health. Unfortunately I believe that this is not the case (see attachment): hush is in a different line.

Can you think of any other reason for this problem?  
However, this d1 $ sound "bd cp" (without 'hush') seems to work fine.

Thanks

Marcelo

I think I see the problem. If you select several lines, they will be executed together. If you select `d1 $ sound "bd"` and `hush`, then the statement `d1 $ sound "bd" hush` is created. For a statement that goes over several lines, you do not have to select the lines explicitly, i.e. type:

```haskell
d1 $ sound "808*4" 
   # pan (sine)
   # cutoff (saw*5000)

```

Then you simply click with your cursor somewhere in the code and evaluate it with Control+Enter. This also works with single-line statements. If you explicitly want to evaluate only this one line, you can use the keyboard shortcuts Shift+Enter.
