reproducer for: CtkBuffer: *collection appears to drop the last item
/* TEST:
wavetable size / precision
CtkBuffer:*collection appears to drop the last item, as a result of setting numFrames to size - 1 rather than size
With the Ctk test below, the returned \b_setn message is:
[ 'b_setn', 0, 0, 15.0, -0.70710676908493, 0.70710676908493, 0.41421353816986, 0.29289323091507, 1.2928931713104, -0.29289323091507, 1.4142135381699, -0.70710676908493, 0.70710676908493, -0.70710676908493, -0.41421353816986, -0.29289323091507, -1.2928931713104, 0.29289323091507, -1.4142135381699, 0.70710676908493 ]
