Tutorial 17Sampling reviewThe keystrokes from the computer keyboard are reported by key, and the select object isused to detect the a, r, and p keys. The bangs from select trigger the necessary messages toadc~, record~, and groove~.Keystrokes are detected and used to send messages to MSP objectsThe keystroke p is also used to trigger the amplitude envelope at the same time as thesample is played. This envelope is used to scale the output of groove~.A two-second envelope tapers the amplitude at the beginning and end of the sample146
Tutorial 17Sampling reviewA sig~ 0.5 object sets the basic playback speed of groove~ at half speed. The amplitude of a3 Hz cosine wave is scaled by a factor of 0.083333 (equal to 1 /12, but more computationallyefficient than dividing by 12) so that it varies from -1 /12 to 1 /12. This sinusoidal signal is usedas the exponent in a power function in pow~ (2 to the power of the input), and the resultis used as the factor by which to multiply the playback speed.Play at half speed, ± one semitone147
