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.
setcps 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
These two values are equivalent:
- Cycles per second: as a decimal,
- Cycles per second: as a fraction,
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.
