Abro este hilo como espejo de los que hay en el foro de Mac y Windows. Así podemos ir conociendo programas y utilidades para este sistema. La manera es poner un pantallazo, enlace, y si se diera el caso alguna cuestión sobre la instalación

:desdentado: comencemos

Simulación sintética aceptable del intrumento de los instrumentos: el órgano de tubo. Permite cambiar la afinación a distintas afinaciones de órganos famosos, aunque por defecto está la temperada.

Está ya en los repositorios de debian testing, y de Ubuntu gusty

Añado un programa que todos conocereis, pero que es un buen sustituto de audition, soundforge o cooledit... Audacity. Pues eso un editor de audio multipista bastante logrado para grabar, cortar, convertir a otros formatos, generar ruidos, transformadas de fourier, fades, ecos, retardos, envolventes, etc...

Pagina del programa:

Añadir que también existe versión de osx y winfool

Mi sinte preferido:

ZynAddSubFX is a opensource software synthesizer capable of making a countless number of instruments, from some common heared from expensive hardware to interesting sounds that you'll boost to an amazing universe of sounds.
The project started in March 2002, and I had written it because I wish to make a synthesizer that produces very beautiful sounds, but which is freely available to anybody who needs it.

Features of ZynAddSubFX:
- realtime synthesizer
- polyphonic (allows playing more than one note at once), mutlitimbral (allows playing more than one instrument at once) synth
- Microtonal capabilities with any scale, any number of notes per octave (well... the no. of notes per octave must be less than 128) and keymapping
- 3 synthesiser engines: 1) first (called "ADsynth" or "ADnote") is a complex engine which makes sounds by adding a number of voices. Each one has filters, envelopes, LFOs, morphing, modulation (Ring Modulation, Phase Modulation... the modulators can have any shape), resonance, etc. Each voice includes a very powerful waveform generator with up to 128 sine/nonsine harmonics. You can use Fourier synthesis or if you don't like it you can waveshaping/filtering of functions. This engine includes antialiasing.
2) second (called "SUBsynth" or "SUBnote") is a simpler engine who allows to make sounds by subtraction of harmonics of sounds from white noise
3) third (called "PADsynth" or "PADnote") is engine that makes very beautifull pads and other instruments.
- Instruments can be orgainzed in kits, which alows you to make drum kits or layered(mixed) instruments; this makes possible to use more than one instrument for a single part. It is possible to choose what items from the kit should be processed by the Part's effects.
- Effects: Reverb, Echo, Chorus/Flange, Phaser,AlienWah (it's a kind of vocal morpher), Distorsion(Waveshaping), EQ, DynamicFilter
- The effects can behave as System Effects or as Insertion Effects; this allows to use many effects at the same time. You can put any insertion effect on any part(or more insertion effects to same parts, if you like so) or you can put the insertion effect to Master output (very usefull if you use the EQ effect). Also, you can have instrument's effect (that is saved with the instrument).
- Filters up to 60dB/octave (or more..); filters can be analogic (LPF,HPF, BPF,etc.), formant(advanced formant filters) and state variable (SVF)
- Envelopes can have ADSR (or ASR, etc..) modes or can be free modes (with any shape)
- Many settings has a "randomness" option, which you can make instruments that every time produces a subtle different sound; this produces a very pleasent effect (like analogue synths or natural instruments that can't produces exactly same sound twice). Because of this, even if it is digital synthesis, it sounds "warm". Listen the ogg vorbis demos from this page to hear this effect.
- the specifications can be easily chaged, so (for example) if you want to change the number of voices or parts to a higher value or to allow a higher number of effects at the same time, there is necessary to chage only a single value from the source file (globals.h) and to recompile the program
- Intuitive and easy to use User Interface with Clipboard and many objects has user presets
- Midi support (supports many controllers) and (if you want) JACK support
- the program has Virtual Keyboard which let you to use it even if you don't have a real midi keyboard
- the graphical user interface can be completely disabled if the user need so
- it is a free program, licensed under version 2 of the GNU General Public License
- there are over 300 high quality instruments included into the package
- many other features.... It is is impossible to describe all this program's features in just a page

Se puede compilar como stand-alone o como plugin, pero yo no he conseguido hacer funcionar el plugin. Los motores de audio y midi se pueden configurar antes de compilar para elegir si se quiere usar alsa, oss, jack, portaudio... Lo normal es que en las distros de binarios venga compilado para jack (y puede que para oss simultaneamente).

Otro sinte muy bueno:

WhySynth is a versatile softsynth which operates as a plugin for the
Disposable Soft Synth Interface (DSSI). A brief list of features:

- 4 oscillators, 2 filters, 3 LFOs, and 5 envelope generators per

- 10 oscillator modes: minBLEP, wavecycle, asynchronous granular,
three FM modes, waveshaper, noise, PADsynth, and phase

- 5 filter modes.

- flexible modulation and mixdown options.

Un sinte que emula la Yamaha DX7:

hexter is a software synthesizer that models the sound generation of a Yamaha DX7 synthesizer. It can easily load most DX7 patch bank files, accept patch editing commands via MIDI sys-ex messages (ALSA systems only), and recreate the sound of the DX7 with greater accuracy than any previous open-source emulation (that the author is aware of....)

Este sinte me mola porque le puedes meter el BPM y excusas de hacer calculos para que los delays cuadren con el tempo... además que se pueden hacer sonidos muy majos :)

PHASEX is an experimental software synthesizer for use with Linux/ALSA/JACK. The name comes partially from its experimental method of using phase offset modulation, where each oscillator can have its phase offset between right and left channels modulated by an LFO or another oscillator.

El FruityLoops de GNU/Linux...

What is LMMS?
LMMS aims to be a free alternative to popular (but commercial and closed- source) programs like FruityLoops/FL Studio, Cubase and Logic allowing you to produce music with your computer. This includes creation of loops, synthesizing and mixing sounds, arranging samples, having fun with your MIDI-keyboard and much more...

LMMS combines the features of a tracker-/sequencer-program and those of powerful synthesizers, samplers, effects etc. in a modern, user-friendly and easy to use graphical user-interface.


* Song-Editor for arranging the song
* creating beats and basslines using the Beat-/Bassline-Editor
* easy-to-use piano-roll for editing patterns and melodies
* instrument- and effect-plugins
* support for hosting VST(i)- and LADSPA-plugins (instruments/effects)
* automation-editor
* MIDI-support

La utilidad estrella para enrutar canales y ponerles cadenas de efectos de paso...
¿Qué pasa, que vuestro host no acepta inserts de efectos? No hay problema, enrutad los canales al Jack-Rack y luego volved a enrutar estos a donde queráis :)
Yo incluso he jugado a meterle efectos a videos en reproductores que no aceptan plugins ladspa de efectos... en vivo. Es muy divertido y sobre todo muy útil si la película que queréis ver se oye como el culo y queréis comprimir la dinámica, normalizar y ecualizar por ejemplo :D
Podéis enrutar tantos canales como queráis...

JACK Rack is an effects "rack" for the JACK low latency audio API. The rack can be filled with LADSPA effects plugins and can be controlled using the ALSA sequencer. It's phat; it turns your computer into an effects box.

Para hacer scratching...

terminatorX is a realtime audio synthesizer that allows you to "scratch" on digitally sampled audio data (*.wav, *.au, *.ogg, *.mp3, etc.) the way hiphop-DJs scratch on vinyl records. It features multiple turntables, realtime effects (buit-in as well as LADSPA plugin effects), a sequencer and MIDI interface - all accessible through an easy-to-use gtk+ GUI.

Caja de ritmos. Funciona MUY bien. Tiene una interfaz muy cuidada, a la altura de las comerciales.

Hydrogen is an advanced drum machine for GNU/Linux. It's main goal is to bring professional yet simple and intuitive pattern-based drum programming.

Sampler de soundfonts:

Qsynth is a fluidsynth GUI front-end application written in C++ around the Qt4 toolkit using Qt Designer. Eventually it may evolve into a softsynth management application allowing the user to control and manage a variety of command line softsynth but for the moment it wraps the excellent FluidSynth. FluidSynth is a command line software synthesiser based on the Soundfont specification.

En realidad sólo es un front-end para el aunténtico sampler que es Fluidsynth, pero lo hace todo más cómodo, ya que este último se ejecuta desde la terminal.
