Wren latest version - 2025.4.10.0

blue hell · Posted: Fri Mar 25, 2022 10:20 pm Post subject:

Version 2022.3.25.0 - and you can:

This release uses an installer - stiil - you must not install Wren in a µsoft owned folder (like program flies, desktop, whathaveyou). The installer may survive that though, but Wren still needs user writable files in the exe folder. The installer should warn about it Cool

For version 2022.3.28.0 I've updated the installer so it can re-install itself. Also source code can now be downloaded from Wren itself.

Reduced the Wren web page to almost nothing, and started a new, nore responsive wiki, that holds the information from the old web page.

HI, while trying to install last version my installation folder changed from C:\Audio\Wren to C:\bin\Wren
I reinstalled again to find the exe file because after the first install Wren didn't copied in the expected folder.
I think it may be corrected.

Hi wikter,

Ah, so it goes a bit messy then ... saw you were in the chat too this morning .. I was still sleeping of course Rolling Eyes

Was it the first time you used the installer?

The current installer should - when you do an upgrade from within Wren itself (help menu) - install over the current Wren.

Howver, when the installer is used stand-alone (which unfortunately has to be done the first time the installer is used), it will not know where Wren is and you will have to tell it during the installation.

You can always solve the issue by copying all Wren files except Wren.ini to where you want it to be.

I'll run some tests here too ... later today ... maybe the installer could issue a warning or something when it can not find Wren, or show a dialog to help find the current Wren.

Hi, it was the first time installed in this machine and I specified c:\audio\wren (and also created a folder to avoid folder owner problems).
I installed it again because I was unaware of where my files went to and again the program changed the path after the second step of the installation.
I did a third "try" after moving & running Wren from the c:\audio\wren
The installer did that c:\bin\wren swap again.

Ah ok, thanks, I see what you mean now - it will indeed mess up the path and it has to be set again after selecting what must be installed.

And this is not what is intended - I will look at it.

Ok, I've updated the installer (to version 2022.5.22.0) and remade the depending installs (for the full installation and the pre-release) to contain the new installer version as well.

And - oh miracle - it was not immediately false flagged by bitdefender as a virus this time. Maybe I should zip the installer better ...

Anyways, I hope this will fix it Rolling Eyes

Blue Hell I have lost track and have a stupid question. Could one say Wren is sonically the same as Nord Modular G2? Or is it a do not compare situation. Thanks sir.

The blog has some update / revision news .. overall though .. I think Wren to be be finished!

I'm out of ideas and out of plans .. i use it .. just that .. use it :)

THANKS SO MUCH!

blue hell · Posted: Tue Feb 07, 2023 10:06 am Post subject:

The input module was not working, made a new Wren version to fix that : 2023.2.7.0.

There is some more info @ https://electro-music.com/forum/topic-73740.html

You should be able to obtain this from within Wren itself (menu: Help / Full update ...).

And if not ... see the blog : https://bluehell.nl/blogje/ or the Wiki : https://bluehell.nl/wren/wiki/doku.php?id=download for more info on downloading and installation.

Hi Jan. I have had some spare time to dig into Wren (though I first installed it a couple of years ago). I just upgraded to the latest version.

There is a bit of a learning curve for me simply because some of the module functions are new to me. However, the patching/interface is pretty intuitive, and I am already getting some nice sounds/textures from it.

I do have a question though ... I would like to send MIDI clock, start, and reset messages:

MIDI CLOCK F8
MIDI START FA
MIDI STOP FC

I tried to use the MidiPnOut module but was unable to get it to work for those messages (though it was transmitting MIDI).

There are other methods I can use but this would be kind of elegant for my application.

Many of the modules have statistical math functions and I can see how WREN can do some wonderful generative music.

It runs very efficiently on my computer (which is a late-model desktop) and it appears I can do some pretty rich things. I may have to "load it up" a lot before I max out the computer here.

Jan, thank you for creating this and offering it to the world. I look forward to using Wren on future work -- particularly on the quarterly streaming events here at Electro-music.com.

Many of Wren's Oscillators have a knob labeled "Warp" on them however I can't find its function in the documentation.

Would you be able to describe what "Warp" does?

Thanks!

blue hell · Posted: Fri Dec 08, 2023 8:27 am Post subject:

Ah .. warp is a sort of generalised PWM .. like it makes longer and shorter "half periods" (edit: which no longer are halves then .. of course ..) for square signals, and so does it for all wave forms.

You may know about the wiki @ https://bluehell.nl/wren/wiki/doku.php (which btw has no info about warping it seems).

but there is some older info too @ https://bluehell.nl/wren/history.php which does use the word warp at times.

Anyway, it makes the wave run faster in one half period than in the other while keeping the total period time constant.

blue hell · Posted: Fri Dec 08, 2023 8:40 am Post subject:

And .. for completeness ... sometimes warping is immplemented for random signals too .. in which case it will do something with probabillities .. like generate more and or wilder changes when the parameter is increased (and then maybe freeze the signal at the current level when set to zero).

Hi. I was wondering if there is an alternate way to get the latest version of Wren... I access the internet on linux or Macintosh machines, but none of my windows machines are allowed out there. That poses a problem to update my 64.2022.3.25 Wren...

Did not take a day .. I think unzipping this one will do, but do not unzip it in a windows owned folder ... I suggest to use C:\bin\wren or just about anything else you prefer . .but not something like program files or downloads (those are windows owned folders with restricted rights).

Note that the file has install in it's name, but there is nothing install about it. It will have to be manually unzipped .. and I think it is complete then and can run.

It does not include the source code - when you need those and can not use the installer .. let me know and I'll put the sources up too.

Enjoy Cool
