Updated - the patch should now work correctly on your own computers. For this Wednesday, Sept. 12, please download this patch (an adaptation of Tutorial 7, Additive Synthesis) and use it to record your own sounds. If you don't have a trial copy of Max/MSP on your own computer, you can use the CAMIL lab - also, this patch doesn't need to be edited, so you can even use MaxMSP Runtime. More instructions are in the patch itself. Have fun!
Please also work through the MSP tutorials 7 (additive synthesis) through 10 (vibrato and frequency modulation).
