• The module consists of a play button, a record button and four sound pads.
• You can freely play the sound pads as long as you’re not recording.
• Press the play button to hear the call of the current stage.
• Press the record button, followed by a sequence of sound pads, to create the required response of the current stage.
• For each stage, the response is the result of changing the call for that stage.
• Add each stage’s response to the final input for that stage. Responses of previous stages do not get changed by future stages. Every stage simply adds four inputs.

Sounds

• K = Kick (bass drum, low sound)
• S = Snare (small drum, sharp short sound)
• H = Hi-Hat (cymbals, short sound)
• O = Open Hi-Hat (cymbals, long sound)

Stage 1

Add up all digits in the serial number, then repeatedly subtract 10 until it falls in the range of 0–9.
If this number is less than 5, change the second sound of the call to an S, unless it already is an S, in which you change it to an O instead.
Otherwise, within this stage’s call, swap all instances of H and O with each other.

Stage 2

If the calls of both stages contain at least one O, swap the first two sounds of this call with the second two. (e.g. 1234 = 3412)
Otherwise, reverse the order of the sounds of this call.

Stage 3

If the number of H across all three calls is 3 or more, make the first sound an O.
Otherwise, within this stage’s call, swap all instances of K and S with each other.
