I would take the output number of the slider box - (which is skipping because of the mouse system, the mouse location system probably.) - take the slider output and then use line between the output values to make extra values.

you might end up with list columns. it isnt one list really. its multiple lists at the same time. then you maybe use numbers and read numbers from the list and they trigger commands.

if you draw a picture or something it might be easier to get suggestions.

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
