This assignment is to make a polyphonic instrument that combines waveshaping and band-pass filtering (vcf~ object) to give you access to a variety of controllable timbres. As with assignment 7, there aren't step-by-step instructions. But here are the things your patch should have:

• An abstraction to play one voice, which should combine a waveshaper (as in assignment 5 but with your choice of waveshape) with a vcf~ object to apply a band-pass filter to the output.
• There should be separate controls for three pitches, an index for the waveshaping, and a filter center frequency. Optionally you can add controls for "Q" (the sharpness of the filter) and/or an offset to the waveshaper. It's not necessary to make this patch play separate "notes" - just a constantly playing set of three voices is fine.
• Make presets that control the parameters to make three or four different choices of pitches and other controls.

Here is the way I organized my controls:

(You don't have to make the patch look exactly like that but there should be controls and preset buttons.)

Here is an example of what it might sound like.
