Part 19: Using MIDI Control.

This is based on Mellite v3.13.8. See https://www.sciss.de/mellite/ for details.

Note that the live camera view of the MIDI controller, being an IP cam streaming to the computer, has a high latency, so the image in the bottom left exhibits a delay of some hundred milliseconds.

Part 17: Changes introduced in 2021.

Part One (0-18 mins): Installation via launcher, implication of splitting objects in the timeline, shallow and deep copies; re-using editor windows, persisting view state; time/frequency information in the audio file editor, spectrum analyzer.

Part Two (18-35 mins): Linking Control/Widget programs with sound processes via expressions, triggers, and actions. Code editor improvements - highlighting symbol uses, rename-refactoring.

Part Three (35-57 mins): Expression programs are like Control/Widget programs but represent expressions, such as numbers, strings, predicates. Various examples of expression programs. Using them as a way to keep algorithmic control on parameters in the timeline editor.

This is based on Mellite v3.12.1. See https://www.sciss.de/mellite/ for details.

Addendum: the 'program-color' object at 54'10" is visually indistinguishable from a constant. In the next version, color programs will be indicated by an equals sign.

Part 13: Stream - streams are "expanded" patterns that persist their internal state. And towards the end, showing the new Oscilloscope view.

This is based on Mellite v2.47.1. See https://www.sciss.de/mellite/ for details.

Try the following more interesting patterns: Brown(60, 108, 2).sliding(4).flatMap(a => a.distinct) or (ArithmSeq(0, 1) % 12 + 72).grouped(12).flatMap(a => a.shuffle).

The first takes the brownian walk and creates a sliding window of four elements (advancing always one element after each window), where the windows are then filtered to contain no duplicates ("distinct" values). For example, if the brownian would produce [100, 99, 100, 99, 98, 99, 97, 95, 96, 97], then the sliding(4) transforms it into [[100, 99, 100, 99], [99, 100, 99, 98], [100, 99, 98, 99], [99, 98, 99, 97], [98, 99, 97, 95], [99, 97, 95, 96], [97, 95, 96, 97]], and the flatMap which is short for map.flatten filters the groups of four elements to contain no duplicates, so [[100, 99], [99, 100, 98], [100, 99, 98], [99, 98, 97], [98, 99, 97, 95], [99, 97, 95, 96], [97, 95, 96]] or flattened [100, 99, 99, 100, 98, 100, 99, 98, 99, 98, 97, 98, 99, 97, 95, 99, 97, 95, 96, 97, 95, 96].

The second produces the wrapped counter 0, 1, 2, ... 11, 0, 1, 2, etc., adds 72 to go into the range of 72 until 84, then randomly shuffles the positions within each group of twelve elements, effectively giving you an "urn" of the twelve pitches of an octave, but always in random order.

This uses a workspace available in the Mellite downloads, which provides a widget for the entire measurement process (behind the scenes FScape and Proc are combined, but this is not shown in detail).

Part 11: The Negatum object which implements a genetic programming algorithm for obtaining synthetic sound structures found by matching against a given sound file.

This is based on Mellite v2.38.1. See https://www.sciss.de/mellite/ for details.

Erratum:

  • at 12:30" the tutorial wrongly states that 67% individuals are obtained through mutation and cross-over. Indeed 100% individuals (so the entire new population of size 500) is obtained this way; the selected individuals are only used as parents.
  • at 14:00" a local maximum is not "actually a valley", but the problem is that a local maximum is surrounded by valleys, so the algorithms avoids descending again into those valleys to potentially reach better maxima.
