yes you take numbers random between 0-100 and then convert to decimal. 0-1 by dividing by 100
and then you subtract point 5 and you get a range between negative point 5 and positive point five.

its like different versions of the same thing I was trying to figure out what you might need and show the other people on here

I guess youre asking for beginner thing so Im just putting a tbf attached to a slider. so when you slide the slider it puts f and then b because trigger is backwards looking.

usually you have to have the keyboard connected before you start pd.

the most recent pd vanilla versions are some sort of mess. I still use 51.4 and I noticed people complaining about versions after that and I never updated. and I dont have the newest problems. so you might get an older pd vanilla and then resave your stuff from that and try it again.

otherwise the sampler things in the regular help files are pretty high end.

the most complicated vanilla only thing around is usually the mike moreno stuff on git hub. hes on youtube with a drumming thing called membrane.

try moon lib as well

you would save it in the top parent patch and send it in when it loads probably.
