This and the following homework are designed with more autonomy, so as to better prepare you for a final project at the end of the quarter. So we'll quit giving you detailed "bullet lists" and instead give you more leeway in how the assignment is carried out. (And, also, this will require you to do more of the planning yourself).
The assignment is to play a sampled voice (download the original voice here) through a bank of three comb filters, to make a major triad. (A major triad consists of three pitches, whose MIDI values are n, n+4, and n+7. For instance, a major triad based at middle C is the MIDI pitches 60, 64, 67). The result should sound like this.
This will require you to go back and revisit sampling from weeks 2 and 3. Note that the patch only plays the phrase "soft and relaxing" from the soundfile (which is a longer sentence). It's OK if you set the sampler up to play the sample in a loop or (better yet, but harder) just once each time a button is pressed.
The comb filters are made as shown in class. Each one makes one of the three pitches (make an abstraction so that you can copy it three times). The comb filters should have a feedback of about 0.98.
Make controls (labeled) to set the base pitch of the triad and the feedback of the comb filters. If you set the base pitch to 0, you get a very crude reverberator instead of a chord.
It's not required for this assignment, but a good way to prepare for your eventual final project would be to practice with presets and settable controls (using the techniques from Feb. 11) by making a couple of presets to make different chords.
Your turned-in zip archive should be self-contained, with the main patch, the abstractions, and a copy of the sample, so that it works out of the box.
