Selecting audio samples based on excitation state

A computer-implemented method comprising:

• receiving, by a computing device, a first musical stimulus;
• determining a velocity associated with the first musical stimulus;
• receiving, by the computing device, a second musical stimulus;
• determining a velocity associated with the second musical stimulus;
• and
• in response to determining that the velocity for the second musical stimulus is the same as the velocity for the first musical stimulus:
• selecting an audio sample for the second musical stimulus that is associated with a musical stimulus having a different velocity;
• and
• playing back the selected audio sample.

A computer-implemented system comprising:

• one or more processors;
• and
• one or more non-transitory computer-readable storage mediums containing instructions configured to cause the one or more processors to perform operations including:
• receiving, by a computing device, a first musical stimulus;
• determining a velocity associated with the first musical stimulus;
• receiving, by the computing device, a second musical stimulus;
• determining a velocity associated with the second musical stimulus;
• and
• in response to determining that the velocity for the second musical stimulus is the same as the velocity for the first musical stimulus:
• selecting an audio sample for the second musical stimulus that is associated with a musical stimulus having a different velocity;
• and
• playing back the selected audio sample.

A non-transitory computer-program product tangibly embodied in a machine-readable non-transitory storage medium, including instructions configured to cause a data processing apparatus to:

• receive, by a computing device, a first musical stimulus;
• determine a velocity associated with the first musical stimulus;
• receive, by the computing device, a second musical stimulus;
• determine a velocity associated with the second musical stimulus;
• and
• in response to determining that the velocity for the second musical stimulus is the same as the velocity for the first musical stimulus:
• select an audio sample for the second musical stimulus that is associated with a musical stimulus having a different velocity;
• and
• play back the selected audio sample.
