I think makenote outputs a midi note number out of the leftmost outlet, and phasor~ needs a frequency value. So I suggest putting a mtof object between them.

I don't know how you can get the velocity to a phasor, maybe it can be scaled to a volume control.

For the duration, maybe send that to a delay object, and when the delay object is triggered it can send a 0 frequency into the phasor. I hope this helps

Hi Balwyn. Wow this is exactly the type of sound I was envisioning. I am going to need to study your patch a little, but it sounds incredible.

So, an audio file is fed into the patch, a soundfiler determines the length of the file in samples. Then a phasor randomly selects a sample to do playback from. And there is forward and reverse audio output.

I adjusted it a little and added a metro with a randomized tempo to generate the random numbers, so the rhythm wouldn't be so even.

But this is really amazing and exactly what I was trying to figure out.

Thank you. Nick

Hi,
I want to play audio I have stored, I guess in an array, but I want the samples not to be played strictly left to right, but some samples shifted in time or order. And if possible, I'd like parts of the array to be read from right to left. When I say right or left I am referring to the timeline of the audio file, from beggining (left) to end (right).

Does anyone have any suggestions as to how to approach this? What i am trying to achieve is a type of glitchy effect when playing an audio file. I also don't want to change the pitch of anything, just the order in which the samples are played.

If anyone has some ideas please let me know. I feel like this is a real typical sound in Max or Pd, but I have never really been able to do it.

thank you in advance for your suggestions.

If I have an audio file entered into an array,

hey, I saw this post and thought skipping a step is an interesting idea.

Here's one version I came up with, but the skipped step is randomized

Hi,

I haven't read the whole discussion, so I don't know if this was mentioned. I've worked a lot with RPi's and Pure data and here are my suggestions from experience.
First, get a Rasperry Pi 4 with 16 gigs of RAM. Since I've been using that I've had no problems, no glitching at all. Also, get rid of all the toggle boxes and number boxes, and any other GUI objects. Use a counter instead of a toggle and use a float object instead of a number box, things like that. I think the gui objects slow down everything.

I hope that helps.

Wow this is amazing. I need to learn the Purr Data objects a little better, but this is pretty amazing. Thank You!

wow thank you @alexandros that looks really great. It seems to work. Maybe I can ask Purr Data people if that is available.

@whale-av thank you for the suggestions. VNC might work. I use it to get into my raspberry Pi sometimes. I am sort of scared it might be a nightmare to set it up on a lot of computers, but maybe it's possible.

I think I might try and see if installing Pure Data on a thumbdrive is an option. that might be easier, and they can keep the thumb drives.

Ok thanks @whale-av. But using a vnc viewer they would just be watching my computer right? or having a view into my computer.
I could just use a projector and show everyone my desktop, but then no one gets any hands on learning.

I don't think chromebooks are windows either, but some kind of Google OS, maybe an Android variant.

Also, I'd rather not use extended because, hopefully, someone will take some initiative and learn Pd on their own, hopefully the latest Vanilla version

Hi,

I might be teaching some kids about synthesis. The school where this might happen doesn't want me to install any software on their computers.

So can Pure Data run in a browser? or are there any ways to have people program Pure Data without installing it on a computer?

Also, can Pure Data run on a Chromebook? I think the OS is just called Google OS.

Thank you.

Nick

@ddw_music Oh that's right, thank you @ddw_music for pointing that out.

There are a lot of good objects for manipulating lists in ELSE. You can probably easily make a row retrograde, inverted or retrograde inverted with ELSE objects, which i think would be some cool variations to have

How is this one? You bang the button and get a new tone row every time.

Hi @whale-av. Thanks for the reply.

I tried your suggestion.

I am getting this error:

inlet: expected 'float' but got 'list'

Any other ideas of what to try?

Thank you.

Hi,
I converted an SDIF file into a text file and I am trying to load it into a textfile object.
I am using an example patch that was using an [openpanel] object, and normally you would manually select the file you want to open, and that works fine.
But I want my version to be automated with a loadbang and read the file upon opening the patch. I tried a few things and nothing is working.

Seems like this should be a simple matter, but it's got me stumped.
I am including an image so you can see what I'm talking about.

Oh I didn't see that zip file.
OK, yes, all these patches open fine.
Thank you!!

Thank you for this link.

It lead me to here:

http://www.ee.columbia.edu/~dpwe/e4896/practicals.html#prac04

The example patches are listed as text. I am having a hard time opening these as Pd files.

I thought if you copy the text and paste it into a text file, then change the file to a .pd file it will open in Pd, but that's not working.

i am getting mostly this in the consol:

#X: no such object

and lot's of other errors. But it's not opening as a file at all. I must be doing something wrong.

thanks for the link.

Hi,

Does anyone have a suggestion as to how to play an SDIF file in Pd? I was doing this a lot in Max, but I haven't yet found a way to do it in Pd.

Sdif files I am getting are output from the Spear program.

In general what I am trying to do is take an audio file and be able to transpose it to different pitches without changing the tempo or degrading the sound. Using an SDIF files seemed to be the best way to do that.

Let me know if you have any thoughts.

@ddw_music
Yes I hear what you are saying. With good filters and good oscillators almost anything will sound good right away. But I think there are a few good filters available for Pd. In the else library or Automatism theres some really good ones, but I haven't found any in Vanilla.

I have never learned Super Collider, although I would really like to, so I can't speak on any comparison, but thanks for your input. Now I want to learn it even more.

I've used Max, Pd, Touch Designer and Open Music.

I like all of them for different reasons. I like Pd the most for music because it is simple and I feel produces the best sound.

I do like Touch Designer too, because I feel like you can get really advanced visual imagery very fast, compared to Gem, Jitter or Processing.

I like the idea of Open Music and I have gotten some insanely cool results with it, but it just never sounded good to me and seems tough to integrate with Pd or Max. Maybe I'll look at it again, I feel like it has potential.
