## Installation

a) Install the boops package for your system

* [Arch user repository](https://aur.archlinux.org/packages/boops.lv2-git/) (thanks to SpotlightKid)
* [Fedora](https://copr.fedorainfracloud.org/coprs/ycollet/linuxmao/package/lv2-BOops/) (thanks to ycollet)
* [FreeBSD](https://www.freshports.org/audio/boops-lv2) (thanks to Yuri): `sudo pkg install boops-lv2`
* NixOS (thanks to Bart Brouns)
* [OpenSUSE](https://build.opensuse.org/package/show/home:geekositalia:daw/BOops)

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

b) Use the latest provided binaries

Unpack the provided boops-\*.zip or boops-\*.tar.xz from the latest release and 
copy the BOops.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](https://github.com/sjaehn/BOops/releases) of B.Oops. Or clone or
[download the master](https://github.com/sjaehn/BOops/archive/master.zip) of this repository.

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`).

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

## Running

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

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/BOops
```

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

Notes:

**Jack transport is required to get information about beat and bar position in the host controlled mode and in the MIDI controlled mode**

**The host must provide information about beat and bar position to use B.Oops in these modes.**
**Pure audio tracks (Ardour) may lack these information. Try to add a MIDI input!**

## Usage

### Quickstart

1) Add an effect by clicking on the [+] symbol below "Fx".
2) Click on the menu symbol left to the effect name to change the effect.
3) Set a pattern right to the effect name to define the timepoint(s) to apply the effect on the incoming audio signal.
4) Continue with point 1 to add another effects. Change the order of the effects by dragging the effect or by clicking on the respective symbol.

### User interface

#### Transport buttons

There are three transport buttons on the top left of the user interface. Play, bypass, and stop.

#### Global settings

The global settings on the top of the user interface contain options to control the source, the transport and the size of
the pattern.

##### Source

Although B.Oops was primarily intended for applying glitch effects on an audio input stream, you can alternatively work
with a sample loaded into the plugin. If you want to go this way, select sample as source and click on the load symbol.
Now you can select an audio file (supported formats include wav, aiff, au, sd2, flac, caf, ogg, and mp3) and the range of
the audio file to be used. The playback of the selected range now always starts with the first step in the sequencer.

You can also choose if the sample is played as a loop or not. But this will only be relevant if the selected range is
shorter than the sequencer loop.

##### Mode

Choose between autoplay, host controlled progression, and MIDI controlled progression. The progression is shown in the
sequencer pattern by a white vertical bar.

You can manually change the beats per minute (bpm) and beats per bar (bpBar) in the autoplay mode. These values as well as
the time or beat/bar position data are automatically detected (host provided) in the host controlled mode and in the MIDI
controlled mode.

The MIDI controlled progression is triggered by pressing a MIDI NOTE_ON signal (e. g., a piano key). You can define the
key(s) which may trigger the progression by clicking on the piano symbol in the global settings line (shows up in the
MIDI controlled mode). You can also define how the sequencer should handle the trigger signal: restart, or restart and
synchronize with the host-provided beat pattern, or continue progression.

![MIDI controlled mode](https://raw.githubusercontent.com/sjaehn/BOops/master/doc/midi_controlled.png "MIDI controlled mode")

There is also an option to select patterns or to directly start an effect by a MIDI signal. See below.

##### Pattern size

Temporal size of a full pattern loop in beat, bars, or seconds.

##### Steps

Pattern size in steps. Set up to 32 steps.

#### Effect slots

![Slots](https://raw.githubusercontent.com/sjaehn/BOops/master/doc/slots.png "Slots")

There are up to 12 slots on the left of the user interface. Each slot is linked to a pattern row right to the respective
slot. The effect slots will be applied in the order from the top to the bottom.

You can add (or insert) an effect by pressing the [+] button or remove an effect by pressing the [-] button. If you have
created more than one slot, you can select a slot by clicking on its name. You can
change an effect and select one out of more than 20 effects by pressing the menu button. You can move the effect slot
(including its respective pattern row) by pressing the up or the down button. To mute or un-mute a slot, press the play
button. |

#### Pattern page tabs

![Pattern tabs](https://raw.githubusercontent.com/sjaehn/BOops/master/doc/pattern_tabs.png "Pattern page tabs")

You can find the pattern page tabs on the top of the centrally located pattern. The tabs provide access to up to 16
patterns. Click on a tab to highlight the tab and to edit the respective pattern. Press ▸ on the tab to switch playback
to the respective pattern. Press the piano keys symbol to enable / disable MIDI-controlled playback of the respective
pattern.

| Symbol | Description |
| --- | --- |
| + | Add a pattern page after the respective page. |
| - | Remove this pattern page. |
| < | Move pattern page backward. |
| > | Move pattern page forward. |

#### MIDI control pattern \#1 - 16

![MIDI control pattern](https://raw.githubusercontent.com/sjaehn/BOops/master/doc/midi_control_pattern.png "MIDI pattern control")

You can move through the up to 16 patterns in B.Oops using MIDI signals (e. g., from a pad controller or a keyboard). The
respective control menu appears upon clicking on the piano keys symbol in the respective tab. Enable / disable MIDI
control of the respective pattern by selection or deselection (= none) of a MIDI status. You can manually set the
parameters to which B.Oops shall respond or you can use MIDI learning. Don't forget to confirm ("OK") or discard changes
("Cancel")!

#### Pattern

![Pattern](https://raw.githubusercontent.com/sjaehn/BOops/master/doc/pattern.png "Pattern")

The pattern matrix is located in the center of user interface. Each line of the pattern is linked to an effect slot in the
left of the user interface. And each line harbors either a sequencer pattern or a shape. You can switch between the two
modes by clicking the respective button on the left of the pattern.

The color of the pads (or the shape) represents the effect of the respective slot. In the pattern mode, the brightness 
represents the pad mix property value. The pad probability property value is shown in the middle of the respective pad 
(only if not 100 %). In the shape mode, the y coordinates represent the mix values.

In the default drawing mode, the pattern is also connected with the pad properties toolbox in
the right of the user interface.

##### Pattern drawing mode

![Pattern mode](https://raw.githubusercontent.com/sjaehn/BOops/master/doc/pattern_mode.png "Pattern drawing mode")

You are in the drawing mode if none of the cut, copy, x-flip, y-flip, or paste symbols is selected. Left-click on a pad to
set the pad and apply properties from the right of the user interface. If you click again, you will un-set this pad.
Dragging results in linked pads. And right-clicking results in copying the properties of the respective pad to the pad
properties in the right of the user interface. Directly change the pad mix property by mouse wheel scrolling.

##### Shape drawing mode

![Shape mode](https://raw.githubusercontent.com/sjaehn/BOops/master/doc/shape_mode.png "Shape drawing mode")

Once switched to the shape mode by clicking on the respective symbol on the left of the pattern, you can edit a shape by
clicking on the shape-harboring pad.

##### Keys-controlled mode

![Keys mode](https://raw.githubusercontent.com/sjaehn/BOops/master/doc/keys_mode.png "Keys-controlled mode")

The keys-controlled mode (MIDI-controlled mode) is the third mode you can choose by clicking on the respective symbol on 
the left of the pattern. In contrast to the pattern or shape drawing mode, you don't predefine the start and end point 
and the amout of an effect. In the keys-controlled mode you predefine keys to respond. The effect will be started if you
then press the predefined key. And the keys velocity represents the amount of the effect.

You can use this mode for more creativity in live performances.

##### Cut, copy or flip mode

Select the mode by clicking on the respective symbol below the pattern. Drag over an area of pads to cut, copy or flip. The
selected pad area is stored in the clipboard.

##### Paste mode

Once you selected the paste option, you can paste the clipboard pads by clicking to any pad in the pattern.

##### Reset, undo and redo

No description required.

##### Load, save and randomize

In addition to the host-provided options to load and save the plugin state including its patterns (e. g., load/save project,
load/save presets), B.Oops also allows to load and save patterns separately from and to pattern files ("*.boos.pat"). This
feature can be used to import / export patterns to other plugin instances or to other projects.

In addition, you can randomize the present pattern by clicking on the dice symbol.

#### Waveform

This input signal waveform is displayed on top of the pattern matrix. Press the shift key and use mouse wheel scrolling to
scale the waveform.

#### Pad properties

The pad properties toolbox (relevant for the pattern drawing mode) is shown on the right side of the user interface.
Properties from the toolbox will be set to the pattern upon drawing new pads.

##### Probability (Gate)

Set the probability for pads to be played or not. Upon drawing a new pad, probability values being not 1.0 are shown on
the pad.

##### Mix

Dry / wet mixing value of an effect pad. Upon drawing a new pad, the mix value is represented on the pad by the
brightness.

#### Slot properties

The slot properties for the selected slot are shown on the bottom of the user interface. The slot properties are applied
for all active pads of a slot. The slot properties consist of ADSR envelope, pan, mix and effect-dependent parameters.

##### ADSR envelope

The ADSR envelope parameters ((A)ttack, (D)ecay, (S)ustain, and (R)elease) are used for each active pad. The values are
relative to one step. This means that (the sum of) attack, decay, and release can take only up to one step (1.00) even if
the pad is longer than one step.

##### Pan

Panning the effect to the left (-1.00), to the right (1.00) or to both sides (0.00). If you pan to the full left, the
right side will get the dry signal.

##### Mix

Dry / wet mixing value of an effect.

##### Effect-dependent parameters

Each effect may provide up to 12 optional parameters. See effects.

### Effects

Once an effect is added to the slots or selected, the effect parameters of the respective slot are shown in the bottom of the
user interface. Temporal parameters refer (like delay) to the size of one step if not stated otherwise.

Some parameters may be provided with a random range option. Drag (or scroll) the white arrows to set the randomization range.

#### Amp

Amplifies (amp > 1.0) or attenuates (amp < 1.0) the input signal.

#### Balance

Balances the input signal to the left (balance < 0.0) or the right (balance > 0.0).

#### Width

Stereo widening of the input signal.

#### Reverb

Simple one parameter reverb, simply set the room size.

#### Galactic reverb

Really big reverb from the Airwindows project. The reverb is controlled by the parameters replace, brightness, detune,
and bigness. Replace stands for the amount of incoming audio signals that should replace the already circulating audio.
Brigtness controls the brigness of the signal by a lowpass filter. Detune shifts the frequency and bigness means the
size of the reverb buffer.

#### Infinity reverb

You can get it even bigger! The extreme and spacy Infinity2 reverb from the Airwindows project.This reverb is controlled
by the parameters filter, size, damp, allpass, and feedback.

#### Delay

Delays the input signal by range * delay steps. Optional feedback.

#### Reverse

Reverse playback.

#### Tremolo

Amp modulation effect defined by its rate (in Hz) and its depth.

#### Chop

Chops each step (or a block of steps defined by the reach parameter) into a number of segments (Nr chops). Each segment can
be leveled up or down. Set the random factor to introduce some variation to the step levels. Soft transition between the
segments can be achieved by increasing the smoothness parameter.

#### Stutter

Stutter effect. Divides each step into segments given by the number of stutters. Soft transition between the segments can be
achieved by increasing the smoothness parameter.

#### Jumble

Plays randomly one of the pads set for the respective slot.

#### Tape stop

Slowing and stopping the playback. Set the time point of the stop by the reach parameter. Set the slowing rate by the
deceleration parameter.

#### Tape speed

Reduces the playback speed (and thus the pitch).

#### Wow & flutter

Mimics the wobbling of old tapes. Divided in low frequency (< 1 Hz, wow) and high frequency (> 1 Hz, flutter) wobbling.
You can set the frequency (rate) and the amplitude (depth) of the wobbling.

#### Scratch

Vinyl scratching. Draw a scratching shape by setting points up and down between 0.0 and -1.0. This will cause a movement
of the playback forward and backward (= scratching). The reach parameter defines the size of the shape in number of steps.
Set the depth parameter to change the amplitude of movement (max. 1 step).

#### Noise

Creates white noise with the given level.

#### Crackles

Creates crackles with the given level. You can change the number of crackles per step (rate), the size distribution (0.0 =
all the same) and the maximum crackle size.

#### Crush

Bitcrusher. Set the upper level limit and the number of bits.

#### Decimate

Lo-Fi effect. Reduces the sample rate.

#### Distortion

Choose between five different distortion methods. Set drive and level limit to achieve distortion.

#### Waveshaper

A waveshaper replaces an input signal (X axis of the shape) by a signal from the shape (Y axis). Fine tuning using
input gain (drive) and ouput gain.

#### Filter

Set lower limit (high pass) and higher limit (low pass) of the  filter range. The roll off parameter is responsible for
the sharpness of the cut off.

#### EQ

Six band equalizer with the parameters sub (~30 Hz), boom (~80 Hz), warmth (~300 Hz), clarity (~1500 Hz), presence
(~4000 Hz), and air (~15 kHz).

#### Flanger

Set the flanger modulation frequency by the modulation parameter and the flanger delay times by the delay (predelay) and
the amount (delay amplitude) parameter. Use mix for the flanger depth. You can add a stereo phase shift and / or a
feedback.

#### Phaser

Set the phaser modulation frequency by the modulation parameter and the phaser filter range by the low freq. and
the high freq. parameter. As the phaser passes the signal through a number of all-pass filters, you can set the number of
filters by the steps parameter. Use mix for the phaser depth. You can add a stereo phase shift and / or a feedback.

#### Ring modulator

Set the modulator frequency and select the waveform from the menu. The amount of modulation is set using the ratio
parameter (0 = full input signal, 1 = full modulator signal).

#### Wah

Draw a shape and set the depth and the reach (in number of steps) to control a bandpass filter to produce a wah effect.
Set the filter with center frequency, bandwidth, and roll off.

#### Banger

The banger modulator effect is a dynamically distorted multi-bandpass filter effect based on B.Angr and thus Airwindows
XRegion. Banger consists of four parameter instances of XRegion. Set the parameters "Gain" for pre-amplification, 
"First" and "Last" to set the distortion & filter range and "Nuke" to change the number of poles for the XRegion engine. 
Set the parameters speed and spin to swing between the instances. This one is really extreme!

#### Tesla coil (experimental)

Simple simulation of a singing big Tesla coil. This feature produces spark-like noises if the input signal exceeds the
threshold voltage. Tesla coils produce an extremely distorted sound. Set drive for the amplification of the input sigal
and level for the level of the output signal.

#### Oops

This is the most important one. Don't run B.Oops without some oops!

#### Surprise box

The surprise box isn't an effect by itself. The surprise box controls if the effect of one of the other slots is applied or
not. Select at least two slots and set the likelihood ratio for each slot.

## Customize

You can create customized builds of B.Oops 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!
