Thanks a lot for all the explanations. I actually had a look at supercollider before but tbh. as a beginner in programming I am quite happy PD keeps it a bit more visually. I think in supercollider I would be even more lost
I've been studying your script the last couple of days and tried to rebuilt it on my own. I already learned a lot. But a couple of things I am quite not sure about.

• for what are you using text search parsing->moses->1000 for? I just noticed it turns voice number 1 into a zero, but don`t really get how and why.
• also I don't fully understand "pd notecount", even you explained already what it does, it lets my brain explode
  You count up + 1 once a note is pressed and count down -1 once its released. I don`t know what's the idea of "max 0" feeding itself back into + though.

Also, I found this from another forum thread you posted, which is an interesting read in general.

It all works as you showed, but when I set list split to 3 it basically freezes PD. Do you know by any chance why?
I would need to split my list into 3 later on.

Thank you again so much for your help

Omg, never in my life would I have figured that out.
Thank you so much. Really appreciate your help.
I think I will be busy for a few days studying it properly.

Yea. That was my initial idea. But it seems like it comes to a similar issue.
What comes out from notein i would need to write into a text. If i play polyphonic I would get multiple notes which i would also need to iterate through at first and bring them in order if I am not mistaken🤔.
It all works if its monophonic. But polyphonic I can't sort it out.

I'm curious, why is that? There's probably a solution. If it's the first time you're using [clone], I can see how it might be tricky to figure out, but "haven't figured it out" may not be the same as "can't use it."

agreed
I should have probably phrase it better.

I am fairly close, but can't solve this last one issue.
Once I am reading out my list, I am iterating through each value, the issue is though, its probably not always in order, which messes up the actual notes.
I guess I would need to go through each list and combine it into another list. So basically I would need to take the next first input of each list(textNotes,textVelocity,textLength) and combine it into another list so that I have pitch, velocity and length in one list for each note, set by the index. I just don`t know how to achieve that.

I thought maybe list split could help? Always just splitting the next first one and writing it into a list for all of them? But I would need to iterate through that as well I guess

Oh man, thank you so much. Looks like I should have checked the help file a bit more carefully.
I’m sorry if those are dumb questions, but it can be quite overwhelming as a beginner.
I really appreciate your help. Thank you

Thanks to everyone for their help! I had to try a few things, but I just can’t come up with a solution.
Basically, I want to feed polyphonic input into a step sequencer — either through [notein] or by manually selecting notes from a virtual keyboard.( a button each sending the pitch for each note)

Using [notein] seemed like the easiest approach at first. I’m storing pitch and velocity in separate [text] objects, and I thought I could just use [text get] to feed that into [poly].
But here’s the issue: [poly] doesn’t accept lists, it expects values to arrive one at a time, as MIDI is a serial process. So instead of feeding a list directly, I would need to send each note individually, one after the other.

I could route each voice separately after [poly] and assign pitch and velocity manually for each voice, but that feels like a lot of effort, and I can’t really use [clone] for my synth setup. That means I’d have to manually duplicate everything based on the number of voices, which isn't ideal. Also I don`t know how to store velocity and note length in this case.

When I try the virtual keyboard approach, I run into the same issue: I have all the note data stored in a list, but I can't feed that list directly into [poly]. I’d still need to read the notes out one by one, in quick succession. On top of that, with the virtual keyboard, I’m not sure how to handle note length, since [poly] manages note on/off internally. I’d basically need to generate my own note on and note off messages manually.

So I think the core issue I’m running into is how to read out a list in a serial way — fast enough to sound like a chord, but still feeding each note individually into [poly].

Also, I found another approach someone did

Thanks a lot for both of your help. It sounds much harder than I expected
Lets say I want 32 polyphony, that would be an insane effort. Even I don`t always use 32 voices, I thought I can keep it more dynamic, depending on how many voices I am playing
The link is very helpful though. Will need to make my way through it.

Hi.

I have built a step sequencer and I would like to record polyphonic notes into it. So far I figured out how to record monophonic notes into a table. But I am bit overwhelmed on how to do that if notes are polyphonic.
Does anyone knows how that would work?

yea. I thought Bela sounded like the better setup, connecting buttons and encoders seems much easier, plus I wouldn`t have any latency issues.
But I probably follow your advice and try it with the raspberry pi first. Its probably also more flexible overall. pisound might get rid of my latency issues as well.

Thanks so much again for all your help

From what I understand, OSC is basically used for transferring messages from Pure Data to the OLED. That's the only information I could find on the Bela website, and it seems like the only way to communicate with the screen.

My main question is, what options do I have for creating a visual representation of what I'm doing in Pure Data if I am not able to use the actual Pure Data GUI? I would love to avoid Python or C++, but it almost seems like there's no way around it. Even then, I don't fully understand how things connect properly. The reason I am asking, if showing the Pure Data GUI is not the right way to go, then I don't really need to waste time making a nice Pure Data GUI in the first place.

Let’s say I programmed a dial in C++; would it essentially need to receive the OSC message from Pure Data and send it to the screen? And how does I2C come into play?

If I have an OLED with a framebuffer driver, would I be able to show the actual Pure Data GUI? I assume that also would to be communicated somehow? If I run a pure data patch on Bela I am not sure if its meant to show the actual GUI in the first place.

I’m really sorry if these are beginner questions, but your help is greatly appreciated. I'm very new to this, and I don’t quite see the whole picture yet in terms of how everything works together. The screen part seems my biggest question mark so far for my project.

Hi,

I am planning a rather ambitious project and just have a question about whether or not what I am planning to do is possible. I apologize if these are basic questions.

Basically, I am working on a Pure Data project, some kind of groovebox with a sequencer.
The part that is still unclear is how to get my Pure Data patch visualized on an OLED screen.

I was considering a combination of a Raspberry Pi and PiSound, or Bela.
So far, I actually prefer Bela, as it already has a good tutorial on how to connect an OLED and communicate with OSC.

Initially, I thought I would be able to display the actual Pure Data interface or GOP (Graph on Parent) on the display, but that doesn't seem to be possible. Even on mobile phones with the Pure Data Android app, it seems to work well.

It looks like the only option is OSC, even though I don't fully understand how it works. From what I understand, it just sends messages and doesn't include graphical elements.

What other options do I have to actually send graphics like dials and sliders to an OLED, rather than just text messages? I have very limited programming skills. Pure Data is fine, and I can figure that out, but C++ is a different story.

Also, is there a way to emulate or test how OSC messages will be received if I were to use an OLED screen?

Oh yea its working now. Awesome. Thank you so much again

Oh wow. Thank you so much.

I just gave it a try, when Iclick on open folder and select my folder the tracklist windows appears but its empty unfortunately, even there are wav files in it.
I will have a closer look. I hope I can figure out why.
Thanks again

Ah thanks, sounds good. I will have a closer look. I already found an oled which should work in theory. But it seems the main issue is that I will just get OSC messages coming through. I won't be able to make anything more graphical like using the sliders from pure data for example. At least I don't know how that would work without heavy programming unfortunately.

Oh awesome. I couldn`t find this. Thank you

I did notice though, things won`t play out as I thought.

My initial idea was to let pure data GOP show up on an OLED display, either on Bela or Raspberry Pi and pisound. But it looks like I won`t be able to show the
actual pure data GUI on it? Does anyone knows more about it? I would basically want to see my pure data interface or GOP on a OLED display.

Hi.

I am having two issues I can`t happen to solve.

1. Lets say I will show my pure data patch on an LCD display. Its normally pretty small, so I would like to switch between different Interfaces and settings.
   Lets say I have a filter page, and an amp page for example.
   How would I be able to achieve that? In max dsp. I am able to hide parts of the interface, so I can just lay multiple interface parts over each other and just hide the ones I don`t want to see.

2. I would like to create a sampler with the option to load samples from a specific folder, but without using the windows file browser. I am basically looking for a way to have a dropdown menu which shows me all the files I have in a certain folder. Lets say I have a Folder for Kicks and it should show me all the kicks in this folder in a dropdown menu. Is that somehow possible? Or any other ideas how I could achieve that considering using pure data on a standalone device like raspberry pi?

Thanks a lot for help in advance
