So I am new to PD and am taking a class. I currently have an assignment due in a few days and I am trying to finish it. I have to design a patch with multiple subpatches that will do to things.

Layer 2 On this layer the sound will play at a normal speed/pitch and it will play every 10 seconds. Gradually, the periodicity of the repetition will start increasing and it will take 2 minutes to end up playing every 5 seconds. After that minute the processes will start again, over and over. In other words, there will be an accelerando in the repetition of the unmodified sound. 2 points Layer 3 On this layer the sound will play over and over but the speed/pitch will change randomly so sometimes the sound will play faster (up to a tenth of a second) and sometimes the sound will play slower (up to 10 seconds). When the file plays faster it will naturally play at a higher pitch, and when it plays slower it will play at a lower pitch. On each repetition the sound should play sometimes forward and sometimes backwards.

Any suggestions on how to do this would be I would like to recieve because I am really confused
