ZynAddSubFX
-----------

ZynAddSubFX is a fully featured musical software synthesizer for Linux, MacOS, BSD, and Windows.
ZynAddSubFX exposes a wide array of synthesis parameters to make it flexible tool for sound design and a fun experience for playing instruments.

Features
~~~~~~~~

*   Polyphonic with support for legato and mono playing modes.
*   Three synthesizer engines:
**      Additive Synthesis for classic synth sounds composed of a variety of voices with powerful modulation. This exposes modulators ranging from LFOs and envelopes to oscillator modulators for FM, PM, and AM.
**      Subtractive Synthesis for creating variable bandwidth harmonics from filtered white noise.
**      PAD synthesis for creating beautiful pads and other instruments.
*   Powerful waveform generator with up to 128 sine/non-sine harmonics.
*   A variety of filters including analogue modeled filters, formant filters, and state variable filters.
*   Envelopes can have ADSR (or ASR, etc..) modes or can be free modes (with any shape).
*   Effects for Reverb, Echo, Chorus/Flange, Phasing, Wave-shaping, Equalizing, Dynamic Filtering with flexible signal routing.
*   Instruments can be organized in kits, which allows you to make drum kits or layered 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.
*   Randomness settings to create subtle differences in each sound to help create that familiar analogue warmth.
*   Microtonal capabilities with any scale, up to 128 notes per octave, and key mapping.
*   Extensive MIDI/Audio driver support including JACK, ALSA, OSS, and PortAudio. The following MIDI protocol extensions are provided:
**      Floating point notes via MIDI SysEx. Allows the exact pitch of a note on event to be specified as a 28-bit value.
**      Per-note controller events via MIDI SysEx. Allows individual active notes to receive MIDI control events.
**      Per-note pitch bend events via MIDI SysEx. Allows individual active notes to change pitch.
*   Session Management Support via LASH/NSM.
*   Plugin Support via DSSI/LV2/VST.
*   Over 1100 high quality instruments included.

Dependencies
~~~~~~~~~~~~

ZynAddSubFX depends on a number of dependencies for building.
For more information on building the core along with the FLTK based interface see doc/building.txt and for building the new interface see https://github.com/zynaddsubfx/zyn-fusion-build.

Required:

- FFTW 3.x.x  - necessary for Fast Fourier computations
- MXML-2.5+   - from https://www.msweet.org/mxml/
- zlib        - from https://www.zlib.net/
- Liblo       - networked open sound control

Optional:

- FLTK (for the oldest user interface)
- NTK  (for the old user interface)
- JACK
- OSS
- ALSA
- LASH
- DSSI
