Music Machine 1 will generate music according to the following parameters: Decision 1: How many voices will play? (choice of 1-10) For each different instrument the following decisions are then made: Decision 2a: Which note will be played? (choice of 1 to 127 (middle C = 60)) Decision 2b: How loud will that note be played? (choice of 1 (almost silent) to 127 (very loud)) Decision 2c: Which sound will be used? (choice of 1 to 128 (see table below)) Decision 3: How long will the notes be held? (choice of 0.25, 0.375, 0.5, 0.75, 1. 1.5, 2, 3, 4, 6 or 8 seconds.

These are equivalent to the following note values at 60 bpm, semiquaver, dotted semiquaver, quaver, dotted quaver, crotchet, dotted crotchet, minim, dotted minim, semibreve, dotted semibreve and breve.) Decision 4: How long before the process repeats? (choice is from the same values as for the held notes with the additional choice of 0 seconds). The machine will run indefinitely until stopped by the user.
