#X text 402 74 The transposition is frequency in Hz. divided by chunk
size in seconds. This patch calculates the loop frequency as a function
of desired transposition;
#X text 77 75 transposition in octaves;
#X text 404 124 Notice now that we get Doppler effects when the chunk
size changes. You can suppress that if you don't want it \, by converting
the chunk size to an audio signal \, sampling and holding it. But then
there would be more work to deal with very low frequencies never triggering
the sample and hold...;
#X text 403 208 You might also want to have a way to retrigger the
loop to sync it with some other process. By the time we had all this
built the patch would be fairly involved. For now \, we'll move on
to note-oriented samplers instead.;
