Assignment 2 is to make a looping sequencer with controlled randomness. There should be a clearly audible loop, but each time through it should vary the particular notes used.

The things you have to do to get this to work are:

• Make a sequencer (16 'notes' would be good) driving a synthesizer. Just an analog-style synth in the style of the 171 final project will be fine (but don't worry about spiffy graphics or having lots of controls.)
• Make some or all of the 16 stages of the sequencer make a random choice between two or more possibilities. You'll probably want to make some choices more likely than others. You can use either the probability-distribution-table strategy (example patch 02.random-table.pd) or the mapping strategy (example patch 05.random-mapping.pd). If the latter, you can repeat some choices to make them more likely than others.
• If necessary, adjust the probability tables so that the result is a believable 16-note sequence, in the sense that you can listen to it and identify a downbeat (the natural place where each repetition starts).
• Please include a prominent 'start' button so it's easy to figure out how the patch should run. You might also want to include volume and tempo comtrols.

For extra credit, incoprporate some strategy such as sampling without replacement to avoid frequent repetition of the same random choices.
