Simulated percussion instrument

A simulated percussion instrument comprising:

• an instrument sensor;
• an audio engine configured to play one or more instances of one or more audio samples on a plurality of audio channels simultaneously;
• wherein the audio engine is configured to, in response to a triggering event of the instrument sensor, play a new instance of an audio sample associated with the triggered instrument sensor by performing the steps of:
• (a) determining if a number of instances of the audio sample already playing is less than a maximum number of instances;
• if (a) is determined false, then (b) stopping play of the instance of the audio sample on the audio channel having a least amount of time left to play thereby making that audio channel available;
• if (a) is determined true, then (c) determining if there is an available audio channel;
• if (c) is determined not true, then stopping play of an instance of another audio sample on the audio channel having a least amount of time left to play thereby making that audio channel available;
• and
• (d) playing the new instance of the audio sample on an available channel.
