SQRT is a multitouch sound board sample player. Tap on the items to trigger different sounds. Drag a triggered sound around the surface to change its parameters. Use the two buttons on the side to change the way how you can play / trigger the sounds. With the pro version you can load in your own sounds (using iTunes or AudioShare) and create your own grids! SQRT comes with a specially designed set of (glitch) sounds by composer/sound designer Ctrl-t (aka Jan T.) and are an incarnation of one of his recent (live) pieces. If you want to use your own sounds, get the pro version! What is special about SQRT? The sounds can be triggered from one point on the screen but the playback behavior can be manipulated over the entire screen. For each 'trigger point' there are snapshots of parameter settings spread across the playing area. The playback behavior is changed by interpolating between these presets. Currently the presets define pitch, loop start and loop length.

skippodisk is a free AUv3 plugin and standalone app. It features algorithm that imitates compact disc reading errors and adds feedback for some comb filtering. controls: * main control is a 2-dimensional slider that changes delay time / buffer size using value on X axis and feedback (positive and negative, -0.997 to 0.997) on Y axis. This control adds some creative comb-like effect. * algorithm settings: 
[ auto ] enables automatic cd skipping. 
[ dropout ] enables adding silence. Use both [auto] and [dropout] with zero feedback value (in the centre of touch control) to achieve the effect of a CD audio glitch * [ bypass ] control and volume control. This slider is in low value state by default.
