Electronic percussion gestures for touchscreens

摘要

Methods, computer program products, and systems for receiving gestures and producing percussion instrument signals are disclosed. An exemplary method includes receiving a gesture on an area of a touchscreen representing a percussion instrument and generating a signal based on the gesture and area. The gesture can be a single point initiation touch on an area, and a drag into another area. The gesture can be a two-touch point initiation touch on a first area, and a change in distance between the points to change a first parameter such as repeat rate. Such gestures can further include translation of the touch points as a group along an axis to change a second parameter such as volume, pitch, or reverb.

1. A computer-implemented method comprising:
receiving, on a touchscreen of an electronic device, a gesture comprising a single point initiation touch on a first area of the touchscreen and a drag into a second area of the touchscreen, where the first and second areas represent one or more percussion instruments; generating a first percussion instrument signal associated with the first area upon receiving the single point initiation touch; and generating a second percussion instrument signal associated with the second area in response to the drag entering into the second area.
