the korg one has a bunch of music for the stock samples

you need to write an explaination so theyll know what your want to do really.

two_pack_four.pd

you could repack them into a 4-pack if you put the first two and then the second two hit the trigger and make the pack go off. then re-unpack them.

its probably fake/ satelite. you need to get someone to really explain it. because it doesnt have a good explaination. you should just use else/mouse. pd vanilla used to have mouse.

@willblackhurst you changed the question so now my response looks weird. the electronic music pd site has a pitch shifter. http://www.pd-tutorial.com/english/index.html

"moon-lib" has a tabread inbetween-er. the bazier formulas are available in pd vanilla somewhere. P1 P2 foci fomulas. one of them is in "context"-lib

the auto-builder thing puts abstarctions into a subpatch. and it will clear the pd box/ subpatch. this is where I usually look. but they have a few links on this site as well.

these files use abstraction placements and clear them.

oh the phasor thinks the period is only the middle copy length. and it starts at the middle copy. so it should go backwards as well.
