Assignment 3 is to make a time-stretched chord out of a vocal sample using the techniques from the "B" example series (looping samplers).

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

• Borrow the overlapping windowed sampler from the Pd "doc" examples (B13) or the example patches from this directory (from class). They do much the same thing, although the "B13" patch is neater and more automated.
• Make the active ingredient into a subpatch or an abstraction (beware of send/receive pairs which will need distinct names) and make three copies. They should share "onset" which should move in parallel for all 3, but should have distinct "chunk sizes" and frequencies.
• Set the three frequencies to a nice ratio like 1:1.5:2.5, adjusting the chunk sizes accordingly to maintain the timbre.
• Make a control that slides the frequencies in parallel (and hence changes the chunk sizes too to maintain constant product of the two.)
• Make a master "line~" to slide the onsets alnog from one end to the other of the sample. You can use the Pd sample (voice.wav) or supply your own.
• Although the chunk size should be protected by a sample-and-hold to prevent clicks, the "frequency" actually can't be, so it can just change discretely.
