• ### Velocity toggle or something?

Hello!
drumkitpd.pd
This is my patch for a midi drum kit. How can I implement velocity sensitivity on/off? I have used [/ 127] objects to turn velocity into a number between 0 and 1 (sincerely, what would I do without you, David). What if I want to toggle velocity sensitivity off? How can I do that? Thank you!

• @flight453 you should learn to use abstractions, basically patches inside patches, by that i do not mean subpatches, i mean other saved .pd files that you call by writing out the path to that .pd file inside an object, and then you will have 1 instance of that patch inside this patch, and you can simply copy that object to have another instance. also, why are you using multiple [dac~] objects, i don't know for sure, but i think that does not work as i belive you intend it to work. try to count the number of stuff you will output to [dac~] and add all of those together until you get one signal to all of them, and divide by the amount that you counted and then output that to [dac~]. also try consider using [poly], i have been trying to do somthing similar before, so somebody told me to use [poly] (probably david), but i didn't understand it, and intended to revisit midi stuff later, and ye, it's for midi, use it on notein, but idk how, you can add arguments to [poly], but idk how it works. you can for instance use [set pad3( (or whatver array you like) on the instances of the patches inside your patch to make those patches output different types of sounds.

• @4ZZ4 thank you for answering! I will try out the things you mentioned and let you know

• My usual formula for velocity sensitivity is:

• normalize velocity to 0 .. 1
• have a "velocity sensitivity" parameter that is also 0 .. 1

Then the final velocity should be calculated as `(velocity - 1) * sensitivity + 1`.

If sensitivity = 1, then the output velocity is the same as the input (full sensitivity).

If sensitivity = 0, then the output velocity is always 1 (completely insensitive to input velocity).

And you can choose anywhere in between (sensitivity = 0.2 means output velocity ranges 0.8 to 1, e.g.).

• @ddw_music genius, i tested this on paper and it works 100%

• @flight453 i have made an abstraction for this, feel free to use as you like. velocity-senitivity.pd just download it and call it in your patch.

when you call a patch (or any normal file) in pd through directory traversing in objects, there are some rules (idk if i know all, because i have just stumbled upon them randomly):
a: to call a patch in the same directory (folder) as your main patch, just type out the name, excluding the ".pd" at the end, so velocity-senitivity.pd becomes velocity-senitivity.
b: to call a patch inside a directory which is inside the same directory as your main patch, just type the directory name for the directory inside the shared directory, then a "/" and then the filename, again, excluding ".pd", so velocity-senitivity.pd inside the directory "abstractions" which shares the directory with your main patch, becomes abstractions/velocity-senitivity. you can go as many directories in as you like, so abstractions/midi&more/velocity-senitivity
c: if it is outside your directory type one "." for as many directories you have to go outside and then "./" (yes, that is a "." followed by a "/") and then your patch name, again, excluding ".pd".
d: you can type what rule "c" says and not entering the patch name, and then type what rule "b" says. here's an example of this in action .../abstractions/midi&more/velocity-senitivity, so the ".../" means that you shold go back 2 directories, and "abstractions/midi&more/" means that you should go inside the folder "abstractions", and then "midi&more", and "velocity-senitivity" is the the patch that you want to use.
e: just typing out the full directory, again excluding the ".pd"

you'r welcome

• @4ZZ4 and @ddw_music thanks for helping!!!
