Stuttering asio for all sound driver caused by too many racks?

Solved .has to do with HALion5 VST ... it has a reverence reverb fx on the channel( cpu hungry)  and the optimalisation for multi- cores was on off...must be set on 4 cores ( has my computer )

Now it is working without stuttering.

  :? I am temporilary lost in Synfire for  now.. :) i like to do something with autochord, live chords and live bass
Autochords i knew it in the past how it works, but now its in my back of my memory ? ..this feature should be visible somewhere on the screen ? .. autochords has also a parameter in the library ..how is this made ?
Can't deduce it the autochords from a known principle right now anymore.

How does this live chords and live bass must be performed in Synfire ?
