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.

@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.

Hey @jameslo. I basically copied what you had in your patch and implemented it in a simpler earlier version of my patch. It totally works and eliminated the click. Genius. Thank you for sharing that.

Here's a version that uses your method to eliminate the click

simple_looper1fix.pd

@jameslo ok awesome. thanks I'll keep working on this.

@jameslo thank you for the info. I am still a noob at a lot of this kind of signal math stuff. I see how you achieved calculating the current playback point in your patch, but I don't understand it. I might just try and copy it and put it into my patch. Thank you for the info.
