Traversing Samples with Granular Synthesis

This sound was generated using an instrument that I developed using MaxMSP tentatively titled the Wave Table Glitch Machine. The instrument uses TouchOSC as a controller running on an iPod Touch. I interfaced the accelerometer on the iPod to a filter so that when turned on with a toggle, tilting it on the y axis causes a lowpass filter to effect the sound. By setting a threshold on the z axis, giving the iPod Touch a brisk shake will cause the patch to loop a randomly selected grain of random length from a randomly selected buffer played back at a randomly selected rate. The variety of sounds possible with five short samples is expansive. Here’s a selection of sound produced with just one sample selected.
