Speck

MAT240C Audio Programming - Final Project

Speck is a grain sequencer inspired by electronic music notation, granular and image syntheses. Grains can be created by chopping samples and applying an arbitrary envelope. They can be placed onto the canvas by drawing with mouse, and when triggered, the canvas translates spatial pixels into note-like structures whose pitch varies based on the vertical location of the note.

Install and Run

• Install Processing

• Add Minim and ControlP5 libraries to Processing

  • Sketch -> Import Library -> Add Libraries
  • Search the name of the library and click Install

• Download / clone the files at:

  git clone https://github.com/merttoka/Speck.git

• Run speck.pde in Processing IDE

Usage

Key	Interaction
LEFT CLICK on wave shape	Sets lower bound of grain selection
RIGHT CLICK on wave shape	Sets higher bound of grain selection (reverses sample if min > max)
LEFT CLICK on envelope	Draws bins on envelope
0 ... 9	Trigger corresponding grain on the dropdown
LEFT CLICK on canvas	Places selected grain on the cell of canvas
RIGHT CLICK on canvas	Removes item from the cell of canvas
SPACE	Start / stop timer on canvas
UP/DOWN	Increment / decrement playback speed
i	Load an image into canvas (image path is in void setup function)
s	Save canvas as an image file
c	Clear canvas
[SHIFT] + LEFT ARROW or RIGHT ARROW	Move timer left or right on canvas (SHIFT doubles the speed)

• You can copy sample files to speck/samples/ directory to populate the samples list.

• The resolution of canvas and total time of canvas can be modified with resolution (canvas matrix dimension) and maxTime (milliseconds) variables at the top of speck.pde

TODO:

• Assign keyboard numbers to play grains
• Draw normalized grain wave
• Reverse sample playback on selection
• Adjustable playback speed
• Image selector
• Labels
• Save grains and canvas on quit
• Editing Grains (delete, manipulate)
• Coloring the grain selection dropdown items
• Interaction improvements
