MDrumSynth uses multi-point (multi-touch) data streams to create a synthesis instrument driven by the relationships between points.

Instead of mapping touch positions (X and Y coordinates) directly to synthesis parameters, relationships such as angle, distance, and velocity compared to other points are used.

MDrumSynth pulls a variety of data from the multi-point interactions. Mapped parameters include: number of active points, points created per second, points held per second, points’ distance and angle to previous, and average X and Y position of all points. This creates an expressive percussion instrument – even without pressure sensitivity.
