Here's what they say about it:
Primarily intended for the creation of rhythmic patterns, Tapatiki offers a large range of tempo sync options (2/1 down to 1/64, dotted and triplet options) as well as non-synced delay times of up to two seconds.
Each tap offers level, pan, feedback and a simple filter. This filter can be placed either within the feedback loop or after it. It offers both low and high pass filtering in a single control. Taps can be individually disabled when not required.
A global feedback multiplier can modify the feedback amount of each channel simultaneously from x0 (effectively killing the feedback) to x2. Although Tapatiki has been tuned to prevent excessive feedback loops, a Panic button is also offered to kill runaway feedback.
The controls have been designed for ease of use e.g. sliders that can be dragged from any point, quickly set a controls value with a right-click, no drop-downs, etc.
