This page will present you all the functions that can be used to concatenate (e.g. add) things together in various ways. 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.
cat, (also known as
slowcat, to match with
fastcat defined below) concatenates a list of patterns into a new pattern; each pattern in the list will maintain its original duration. For example:
There is also a
slowcat function, perfectly similar to
cat. This function exists as a mirror of
fastcat works like cat above, but squashes all the patterns to fit a single cycle.
timeCat is like
fastcat except that you provide proportionate sizes of the patterns to each other for when they're concatenated into one cycle. The larger the value in the list, the larger relative size the pattern takes in the final loop. If all values are equal then this is equivalent to
fastcat (e.g. the following two code fragments are equivalent).
randcat is similar to
cat, but rather than playing the given patterns in order, it picks them at random. For example:
append combines two patterns into a new pattern, where cycles alternate between the first and second pattern:
It has the alias
slowAppend, in sympathy with
fastAppend, described below.
fastAppend works like append described above, but each pair of cycles from the two patterns are squashed to fit a single cycle.
wedge combines two patterns by squashing them into a single cycle. It takes a ratio as the first argument. The ratio determines what percentage of the pattern cycle is taken up by the first pattern. The second pattern fills in the remainder of the pattern cycle. For example:
brak makes a pattern sound a bit like a breakbeat. It does this by every other cycle, squashing the pattern to fit half a cycle, and offsetting it by a quarter of a cycle.
flatpat takes a pattern of lists and flattens it into a pattern where all the events in each list happen simultaneously. For example, the following code uses flatpat in combination with listToPat to create an alternating pattern of chords.
This code is equivalent to:
run function generates a pattern representing a cycle of numbers from
n-1 inclusive. Notably used to
run through a folder of samples in order:
The first parameter to run can be given as a pattern:
scan is similar to
run, but starts at 1 for the first cycle, adding an additional number each cycle until it reaches
