  • Autoplay or host or host + MIDI controlled playing
  • User defined pad features: Gate, note pitch, octave pitch, velocity, and duration
  • Optional individual randomization of each pad feature

Installation

a) Install the bsequencer (bsequencer-lv2) package for your system

Note: This will NOT necessarily install the latest version of B.SEQuencer. The version provided depends on the packagers.

b) Use the latest provided binaries

Unpack the provided bsequencer-*.zip or bsequencer-*.tar.xz from the latest release and copy the BSEQuencer.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: Clone or download this repository.

Step 2: Install pkg-config and the development packages for x11, cairo, 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 lv2-dev

On Arch-based systems you may run:

sudo pacman -S base-devel
sudo pacman -S pkg-config libx11 cairo 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. Alternatively, you may build a debugging version using make CPPFLAGS+=-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) or even define DESTDIR.

Optional: Further supported parameters include LANGUAGE (usually two letters code) to change the GUI language (see customize).

Running

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

If jalv is installed, you can also call it

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

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

Usage

See https://github.com/sjaehn/BSEQuencer/wiki/B.SEQuencer

Presets

B.SEQuencer comes along with a set of factory presets including arpeggios and drum patterns. You can also import the large collection of Tidal Cycles drum patterns made by LVM from https://github.com/lvm/tidal-drum-patterns using the Importpattern tool: https://github.com/sjaehn/Importpattern .

Customize

You can create customized builds of B.SEQuenzr using the parameter LANGUAGE(e.g., make LANGUAGE=DE). To create a new language pack, copy src/Locale_EN.hpp and edit the text for the respective definitions. But do not change or delete any definition symbol!
