Yoshimi is a software audio synthesizer, originally forked from ZynAddSubFX
Three separate engines
each with distinctive characteristics, can be used together or individually
Sixteen engine kits for the ultimate in multi-layering of engines, or for synthesized drum kits
manage up to four independent sounds on any channel with faders or an X/Y midi joystick
step through up to 16 sounds seamlessly while playing in real time (including vector sounds)
Scala-compatible scales and keymaps
capture almost all internal controls and many switches with ordinary 7-bit values, or NRPNs, or even 7-bit NRPNs, then edit the responses
Command Line Access
headless operation and high accessibility, for those with sight- or motor control issues
Rich variations of tone and timbre
Yoshimi provides the means to ensure no two notes are ever identical - just like in the real world.
And much more...
