Here’s an interesting synthesizer based on a Macbook Pro’s Trackpad. I like futuristicish things and MStretchSynth surely fits that bill. If this interface gets tied to user generated samples it’s going to be great.
“‘MStretchSynth’ 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. ‘MStretchSynth’ uses angle, distance and total velocity between points to map to synthesis parameters pitch, amplitude and delay depth.” – Kevin Schlei
