Hello Atte,

I never try LASH yet, but something I can say is that Zynaddsubfx is not
enough reliable to do realtime work in combination with jack and other
softwares. Hydrogen is far better but not completely safe. Seq24,
Ecasound, Sooperlooper are rock solid.

This is strictly the result of my experience.
