Summary0009964: Recording waveshape laggs
DescriptionWhen in recording waveshape takes few seconds to generate
It is an issue when tracking double instruments when you have to relly
On visual recording...
The recording section dont have that issue it renders waves in realtime (gain section)
I heard its because it renders waveshape from ssd and not directly from ram
Every major daw has this sorted up,and none of them do this
It fells like it laggs big time

> We only update once data has been written to disk. We are attempting to show you what has been immutably (hopefully) captured, rather than keep up with real time.
> Other DAWs are just keeping with real time, regardless of whether the data is on disk yet or not.

Most OS file-systems flush data to disk in 5 second intervals.
There is also additional buffering in Ardour Preferences > Performance, by default up to 5 seconds.
