@mkdewolf Welcome to the forum...!
Your whole patch is not in the zip I think.
But it looks like you are using an array, which only gives one piece of data per index.
You can have many arrays of course.
But you could try [text] which can save many parameters for each row (index).

Thanks.
How can i specify dynamic and duration in text? Does array read this?

@mkdewolf I'm wondering if you're aware of Pd's help system? For instance, you could create a [text] object, right click it, and choose help to get all the info you need about [text]. There are also tutorials on how to do things in Pd. Click Help->Browser...->PureData->3.audio.examples/ for ones related to audio. In particular, A02.amplitude.pd describes how to control volume. If you fill us in more on how you are generating notes we might be able to suggest tutorials on how to control their duration.
