Performance
This page will present you all the functions that will be useful during the performance: tempo management, reset, etc... Each function will be presented following the same model:
- Type signature: how the function is declared on the Haskell side.
- Description: verbal description of the function.
- Examples: a small list of examples that you can copy/paste in your editor.

is a global function that adjusts the number of cycles per second. This function can accept integers, decimals, and fractions.
The default number of cycles per second is 0.5625
, which is equivalent to 135/60/4
.
These two values are equivalent:
- Cycles per second: as a decimal,
setcps 0.5625
. - Cycles per second: as a fraction,
setcps (135/60/4)
Representing cycles per second using fractions has the advantage of being more human-readable and more closely aligned with how tempo is commonly represented in music as beats per minute (or bpm). Techno has a range of 120-140 bpm
. House has a range of 115-130 bpm
. And so on. If we wanted to set the tempo of our Tidal song to fast house, we would do the following:
Regarding the example above, the first part of the fraction (130/60)
says there will be 130
beats per minute. 130
is the number of beats and 60
is the length of the minute (60
seconds). The second part of the fraction (/4
) says that for every cycle in tidal there will be 4
beats. You can adjust this value to change how quickly your cycles run.
