Henning: Controlling Frequency

sine scratch

In this patch the movement in x-direction is mapped to the frequency of a cosine wave oscillator. The movement in y-direction is mapped to the amplitude of the cosine wave. Media:sine.pd

Henning: Visual Scratch

In this patch the movement in x-direction controls the index of an array. The array contains the data of a sound file, so the index points to a position in the sound file. Through movement the pointer plays the sound file. Media:sound files.zip Media:scratch.pd
