Blows out low sounds from below to spice up your music production with a special flavour.

B.Low

B.Low is the unique sample-based sound generator plugin you always waited for. It blows out low sounds from below to spice up your music production with a special flavour. The high quality samples were gratefully provided by numerous international artists (see b-low).

Released on April 1, 2022

Installation

Choose one of the following options:

a) Install the blow package for your system (once established)

b) Use the latest provided binaries

Unpack the provided blow-*.zip or blow-*.tar.xz from the latest release and copy the BLow.lv2 folder to your lv2 directory (depending on your system settings, ~/.lv2/, /usr/lib/lv2/, /usr/local/lib/lv2/, or ...).

c) Build your own binaries in the following three steps.

Step 1: Download the latest published version of Low. Or clone or download the master of this repository including the submodules. For git cloning use:

git clone --recurse-submodules https://github.com/sjaehn/BLow.git

Step 2: Install pkg-config and the development packages for x11, cairo, soundfile, and lv2 if not done yet. If you don't have already got the build tools (compilers, make, libraries) then install them too.

On Debian-based systems you may run:

sudo apt-get install build-essential
sudo apt-get install pkg-config libx11-dev libcairo2-dev libsndfile-dev lv2-dev

On Arch-based systems you may run:

sudo pacman -S base-devel
sudo pacman -S pkg-config libx11 cairo libsndfile lv2

Step 3: Building and installing into the default lv2 directory (/usr/local/lib/lv2/) is easy using make and make install. Simply call:

make
sudo make install

Optional: Standard make and make install parameters are supported. You may build a debugging version using make CXXFLAGS+=-g. For installation into an alternative directory (e.g., /usr/lib/lv2/), change the variable PREFIX while installing: sudo make install PREFIX=/usr. If you want to freely choose the install target directory, change the variable LV2DIR (e.g., make install LV2DIR=~/.lv2).

Running

After the installation Ardour, Carla, and any other LV2 host should automatically detect B.Low.

If jalv is installed, you can also call it using one of the graphical jalv executables (like jalv.gtk, or jalv.gtk3, or jalv.qt4, or jalv.qt5, depending on what is installed), like

jalv.gtk https://www.jahnichen.de/plugins/lv2/BLow

to run it stand-alone and connect it to the JACK system.

Frequencies below 40Hz missing

Hello and thanks for this mind-blowing plugin.

Is it only me, or does it miss the frequency range b.low 40 Hz? Maybe I m affected by hearing loss, could be possible.

And how can I contribute to additional blow samples? Is there an upload repository for this?

kind regards
