The musical possibilities of force sensors on touchscreen devices are explored, using Apple’s 3D Touch. Three functions are selected to be controlled by force: a) excitation, b) modification (aftertouch), and c) mode change. Excitation starts a note, modification alters a playing note, and mode change controls binary on/off sound parameters. Four instruments are designed using different combinations of force-sound mapping strategies. ForceKlick is a single button instrument that plays consecutive notes within one touch by altering touch force, by detecting force down-peaks. The iPhone 6s/7 Ocarina features force-sensitive fingerholes that heightens octaves upon high force. Force Trombone continuously controls gain by force. Force Synth is a trigger pad array featuring all functions in one button: start note by touch, control vibrato with force, and toggle octaves upon abrupt burst of force. A simple user test suggests that adding force features to well-known instruments are more friendly and usable.
