@hansr Fascinating sounds!

For some reason, my post with a Bandcamp link doesn't show up here. Does anyone know whether there is a problem with pdpatchrepo.info? This post is the only new post that has shown up in the past 10 days.

@jameslo Your expr~ version has some interesting properties. When I input a sine wave and set $v2 to an odd integer, the output is a sine wave whose frequency is $v2 times the original frequency. You would never get sine wave output from traditional wavefolding implementations. When $v2 is an even integer, you get odd harmonics (as expected) with a peak at the $v2-1 harmonic. I'll continue to use traditional techniques for wavefolding, but I think your expr~ could be very useful for something else I'm working on. Thanks for posting it!

Edit: I've been experimenting more with this. The behavior I described above occurs when the input sine wave has an amplitude of 1 to -1. If the amplitude is less than that, you get a limited number of harmonics. For example, if the sine wave's amplitude is 0.99 to -0.99, and $v2 is an odd integer, you get a large peak at the $v2 harmonic, small peaks at lower harmonics, and no peaks at higher harmonics.

@kyro Thank you!

@kyro This looks interesting. Do you have a sample patch?

I found a way that works:

@whale-av Thanks. Where would I get concat? It isn't listed in deken. Is there a way to do this in vanilla Pd?

When I put 0111 in a symbol object, or in a symbol message, Pure Data deletes the leading zero. I need the leading zero to be there because it is the start of a file name. How do I get Pure Data to stop deleting the leading zero?

@mosef123 You're also missing edge~, so you probably need the cyclone library. There are a number of tutorials that tell you how to make your own oscilloscope. Here's one:

The dashed box around speedlim means that you don't have that object. You should have gotten a message in red on the pd console to indicate that problem. There are several external libraries that include speedlim. You need to decide which one to use. Where did you get the oscilloscope subpatch? It would be a good idea to use the same speedlim that they used.

@whale-av Thanks! This looks promising. I'll give it a try.

Edit: That worked thanks!
