Yoshimi is a software synthesizer for Linux based on the 2.4.0 release of ZynAddSubFX, written by Nasca Octavian Paul. Yoshimi delivers the same synth capabilities, along with very good Jack and Alsa midi/audio functionality.
I've been a ZynAddSubFX lover pretty much since it was first offered. Sadly though, Zyn has long been a case of flawed genius. It's audio and midi capabilities have not kept pace with the evolution and infrastructure improvements of Linux audio. More Info »
Performance with Jack was poor. Of recent years I've become more demanding in that respect, so I started looking at the code. I tried working with the official project team, but it proved impossible. We have vastly different and somewhat incompatible design, development and performance philosphies.
And so Yoshimi came to be, as a Linux only derivative of ZynAddSubFX. Yoshi attempts to do everything original Zyn does, but to do it well on Linux. A number of people have given time and energy to bring Yoshimi to life (and keep it that way!). My thanks go to you all.
