Uber Synth is a polyphonic multi-timbral frequency modulated (FM) synthesizer that runs on any iOS device. The underlying sound engine is based on the triple-oscillator cross-modulated FM synthesizer first introduced in our xMod app. Uber Synth provides five multi-timbral options: 1) Mix the sounds of any two sound patches, 2) combine patches using the sound map, 3) Generate specified as well as randomized sound palettes across the keyboard, 4) Specify a region in sound space centered on a sound and move a point by a variable randomized amount within the region each time you play a note to create an evolving mix of the center sound and the sound nearest the point. 5) Do the same as above moving the point automatically at a specified rate. Supports Audiobus.
