A software synthesizer for Linux, originally forked from ZynAddSubFX (Copyright 2002-2009 Nasca Octavian Paul) in 2009 by Alan Calvert. Initially, Yoshimi delivered the same synthesizer capabilities. After early improvement of Jack and Alsa midi/audio performance, now many new features have been added, and we are concentrating on accessibility.
Yoshimi comes with a built-in User Guide, and there is also a highly detailed Advanced Reference Manual under continuous development: https://github.com/Yoshimi/yoshimi-doc/raw/master/pdf/yoshimi-advanced-reference-manual.pdf
ZynAddSubFX is a powerful realtime, multi-timbral software synthesizer for Linux, OSX, and Windows. It is microtonal, and the instruments made by it sounds like those from professional keyboards. The program has effects like Reverb, Echo, Chorus, Phaser...
This program was created to provide a way to interact with the sound effects of those two synthesizers : ZynAddSubFx and Yoshimi, from a real midi keyboard, or any midi surface controller or any midi device or software able to connect to a Jack system and send Midi messages.
For now, only the effects levels can be modified. All the other parameters need to be adjusted as usual in the software interface.
Partita is a sound synthesis software based on ZynAddSubFX. Apart an entirely redesigned GUI it offers new functionalities: extended MIDI control and higher degree of abstraction for managing instruments (sounds) creation.
