add_modules

Anonymous (anonymous@undisclosed.example.com) — 2022-03-29T21:51:27+00:00

Add modules There are a couple of ways to add modules to a patch. The regular way would be to drag them out of the module selector and drop them into the patch window. The patch window also has a right click context menu which will allow you to select a module to insert.

Add wires Click and hold on a connector and then drag to another connector, then release the mouse button. You can connect inputs to inputs and inputs to an output. It is not possible to connect an input to multiple outputs, and it is not possible to connect an output to an output.

bad_sound

Anonymous (anonymous@undisclosed.example.com) — 2022-03-31T21:54:21+00:00

Bad Sound Try setting the sample rate higher. Out of the box Wren used to run at a sample rate of 44.1 kHz, setting it to 88.2 kHz or 96 kHz makes it sound a lot better. As of version 2015.9.10.0 I've made the default sample rate to be 88.2 kHz, but when you have an earlier install the existing INI file may still set the sample rate to a lower value. So, please check the Settings Screen

Module help All modules have some built in documentation, you can use F1 on a selected module to see it. When doing for this the first time (or after a program upgrade) the program may have to regenerate the help files, causing some display clutter. The information will be shown in your default web browser.

no_sound

Anonymous (anonymous@undisclosed.example.com) — 2022-03-31T21:53:46+00:00

Wren makes no sound You will need to select a sound output device from the setup/Audio devices main menu. You will need an output module in the patch to route the patch signals to. Mute may be on, in which case there will be a flashing yellow sign in the top pane indicating this. Use the Action menu to toggle this. The Action menu will also show the current keyboard shortcut for this.

non_windows_folder

(Non) Windows owned folder Windows does not like writing arbitrary files in arbitrary folders / directories. The Blue Hell tools usually do write things into the same folder as where the executable is, and when that happens to be a folder that is owned by windows things will not work.

stuttering_audio

Anonymous (anonymous@undisclosed.example.com) — 2022-03-31T21:54:48+00:00

Stuttering audio When NOT using ASIO, in the device selector (main menu: setup/Audio devices) use a buffer size like 2048. You can set a buffer size of zero, in which case the PortAudio DLL will decide on a buffer size. When using ASIO the buffer size setting is ignored, and the size recommended by the ASIO driver is being used instead. So for ASIO you will need to set the buffer size from the ASIO control panel (and should set the buffer size in

Pre-release installation The pre-release in principle is a single executable file, and it assumes that a full Wren installation was performed before. With Wren version 2022.3.25.0 or later this can be done from within Wren - but it needs Installer.exe to be present in the folder containing Wren.exe for this to work.
