Algorithm Composition

py4pd offers a list of objects to create algorithm composition, they mimic some obcjets of OpenMusic.

I am yet implementing most of OpenMusic objects

Visual Language

Lisp

Basic functions defined in the programming language

• py.first: Returns the first element of a list.
• py.second: Returns the second element of a list.
• py.third: Returns the third element of a list.
• py.nth: Returns the element at a specified index in a list.
• py.rest: Returns all elements of a list except the first.
• py.nthcdr: Returns all elements of a list starting from a specified index.
• py.butlast: Returns all elements of a list except the last.
• py.reverse: Returns a new list with elements in reverse order.
• py.length: Returns the number of elements in a list.
• py.list: Converts arguments into a list.
• py.remove: Returns a list with all occurrences of a given element removed.
• py.cons: Constructs a new list by prepending an element to an existing list.
• py.append: Concatenates two lists into a single list.
• py.apply: Calls a function with a list of arguments.
• py.funcall: Calls a function with given arguments directly.
• py.mapcar: Applies a function to each element of a list and returns a list of results.
• py.mapcan: Applies a function to each element of a list and concatenates all results into a single list.

Control

Special boxes implementing control operators, argument passing and memory

• py.seq:
• py.hub:
• py.split:
• py.default:

Loop

Special boxes for visual loop implementation

Special symbols:

• py.iterate: Iterate over a list.
• py.collect: Collect items. Must work with py.iterate.

Basic Tools

Objects and tools for data representation and processing

Arithmetic

• py.+: + lists, number and list with number.
• py.-: - lists, number and list with number.
• py.*: * lists, number and list with number.
• py./: / lists, number and list with number.
