Here are a list of terms used in LMMS and and a short explanation. In addition we have included few musical terms. When communicating with other musicians and developers, please use the correct terms, as this will be more efficient and easier for both parts.


Setting the position of a knob or other control in LMMS over time by a manually-drawn envelope. Automation is edited in the Automation Editor for individual controls. See the article on Working with Automation for a more task-oriented description.
A capella
Singing a song without instrument accompaniment.


Bit depth
The resolution of each sample. The number of volume steps in each sample. The number of bits in each sample.



In respect to projectfiles: Making a file smaller. A compressed LMMS project is a MMPZ-file. It will be significanly smaller on disk than the uncompressed project MMP. However a MMPZ-file will be lost if it somehow are flawed, whereas MMP-files that has a flaw, can be partly or completely rescued!
In respect to audio-files: Compression can be done in two ways: 1. Lossy compression makes the file smaller by loosing (unimportant) information (bits). Ogg and mp3 are examples of lossy compressed audio files. 2. Lossless compression makes the file smaller by writing it in a smarter way (like zip files), thus no information get lost. Flac is an example of lossless compressed audio files.

Reduces the dynamic range by amplifying quiet sounds and reducing the volume of loud sounds. In fact you can see compression as if you press a harmonica closed. The distance between each fold of the bellow get smaller, that will also be the case of the peaks in a sound-spectrum, that is being compressed. The most prominent changed is more punch to the sound, and that is why compression is used a lot in percussion! This is a science in itself, with a lot of possibilities, thus you should read more about compression to understand why the first sentence isn't necessarily true.
Every interface item in LMMS is known as a control.
Setting the position of a knob or other control in LMMS over time by a generated envelope such as an LFO. This differs from automation because automation is drawn manually by the user, and is often not a repeated effect such as a sine, square or saw wave, whereas controllers use such waves to give a regular pattern to a control.


A math expression that influence an effect negatively. You will find Damping on effect like reverb and echo plugins.
A curve in envelope-settings that controls how a sound-signal goes from max to silent, over time.
When about music/sound: Dry sound is a term used on sound without any influence of an effect. Completely dry means that the effect is nullified
Dynamic range
The ratio between the strongest and weakest sound in a song. A song with high dynamic range have very weak and very strong sounds.


Abbreviation for Equalizer. An equalizer adjusts the balance between frequencies (by adjusting the amplitude of audio signals at particular frequencies). Equalizers often appear as frequency-specific volume knobs, but LMMS also contain a parametric graphic EQ, that has controls for visual curves.
An envelope is a way to control how the sound changes over time. From when the sound starts, while the note is held at a stable level, to when the note ends. The ADSR envelope is perhaps the most common, it consist of ways to control the attack, decay, sustain and release.


A filter alters the frequency spectrum of a sound coming out of an oscillator. Common filters are low-pass (meaning low frequencies are let through), high-pass (allowing high frequencies through), notch (blocking a narrow range of frequencies), and band-pass (allowing only a narrow range of frequencies). Filters, even in the digital world, cannot be truly linear - i.e. the graph of the filter's response over frequency shows a curved 'knee' dropping down rather than a vertical line. This means that a low-pass filter set to 100Hz will let some frequencies lower than that through, although the lower the frequency the more it will be cut. The steepness of the drop in a filter is called it's Q parameter. Historically, some analogue filters also introduced 'resonance' or amplification of frequencies around the 'knee' point in the filter - this effect has been used in much electronic music and is included in LMMS.
Short for Effects.







LADSPA is an acronym for Linux Audio Developers Simple Plugin API. It is a standard for handling filters and effects, licensed under the GNU LGPL. It was originally designed for Linux through consensus on the Linux Audio Developers Mailing List, but works on a variety of other platforms. It is used in many free audio software projects and there is a wide range of LADSPA plugins available.
Acronym for Low Frequency Oscillator. Popularly expressed i sound going through a LFO, will vibrate or oscillate, in a controlled frequency. LFO typically refers to oscillators whose usual frequency is in the 0.1Hz - 10Hz range - i.e. from one beat every ten seconds to ten beats every second. Above this frequency the oscillator is generating frequencies in the audible spectrum and the 'low frequency' prefix is not used. LFOs are typically used to control things such as filter sweeps and amplitude oscillation ('vibrato').
Originally acronym for Linux MultiMedia Studio. Today it runs on the platforms Windows, Linux and soon Mac too, and LMMS is therefore an abbreviation of your choice.





Ogg is a free, open standard container format maintained by the Xiph.Org Foundation. Similarly to MP3, it is designed to provide efficient streaming and manipulation of high quality digital multimedia.


Peak Controller
A Peak Controller is similar to a noise gate, but with greater flexibility. Peak controllers are commonly placed on a percussion track, and then use the output signal to control the volume of another sustained sound. This results in the sustained sound being chopped up in time with the percussion, and has been used by artists such as Madonna (vogue) and Seal (crazy) to create very distinctive sounds.
Effect that over a controlled time (Hz) moves the phase of all wave-spectrums, that is passed into the plugin. This creates 'fuzzy detune' changes in the output. Phasers are widely used in EDM
The entire package of instruments, tracks, patterns and settings that comprise the whole performance of the song. This is what you save and load from the Project menu. It is your saved file.

In LMMS we have to different types: Uncompressed .MMP and compressed .MMPZ


The steepness of the cutoff of a filter.
The Q in the Automation Editor and Piano Roll. Assumed short for Quantization: The "resolution" of notes and automations.


Short for reverberation. Umbrella term for an echo effect.


An individual audio file, used either in an instrument (see AudioFileProcessor Plugin) or a Sample track.
The term covers extracting pieces of sound-spectrums from existing spectrums, and saving those in specific sound-files. These are now called Samples.
Sample rate / Sample frequency
How many times per second the signal are measured.
Sample Track
A type of track that is designed to take audio files. Multiple different Samples can be placed in one sample track, and they can overlap. See Working with Samples.
Aka Block visual and manipulable item in a track that contains either a sample (in the case of a sample track), notes in a piano roll or patterns of a beat / bassline. Each type of track only uses one type of segment. See Song Editor.
The overall combination of tracks playing simultaneously that makes up your composition. See Song Editor.
A term used to describe all the different frequencies in a sound. The effect plugin Spectrum Analyzer displays the different frequencies present in that FX-channel.
A Beat + Bassline Editor term. One sixteenth of a bar in the ; a single "tab" or "tombstone" in the pattern display.


A mmpz file with either preloaded instruments, samples and/or automation tracks. By clicking new project you load the default template; a mmpz file with a Triple Osc track, Sample track, B+B track and Automation track in the Song Editor, and a Kicker instrument in the B+B Editor.
A row in the Song Editor containing an instrument, sample track, or beat/bassline.



Acronym for Virtual Studio Technology. Programs or plugins which tweaks or produce sound. They use the .dll extension and is supported by LMMS. VSTi (Virtual instrument) is a common name for VST´s which generate sounds and signals, like any other instrument plugin. These are loaded through VeSTige. VSTfx (VST effects) are used to describe VST´s which tweaks or changes signals, like any other effect plugin.


Waveform Audio File Format. A cross-platform uncompressed audio standard.
When about music/sound: Wet sound is a term used on sound with influence of an effect. Completely wet means that the effect is maximally expressed in the output. This does not mean that the dry part is inaudible, it only means that the effect is maxed out.

When about music/sound: The sound width describe the stereo impression. A wide stereo is expressed as if the sounds of each stereo-channel are far away from each other, whereas a narrow stereo appear more condensed, in what often is calle the stereo-landscape. Effects which increase the stereo is commonly called stereo wideners. To achieve this effect various techniques can be used, the most easy is delay between right and left channel.
