Hi. Just to make sure we’re talking about the same thing : in PT you use write auto to selection for eq or else, in latch mode with latch prime in stop, right ?
If so, the best way IMHO to do the same on nuendo is to work with the preview mode (100 log, no need for a giant-Ilok-icon-console;-)) and the fill loop option.
Works like a charm, absolutely no need to open auto tracks, which can quickly become a mess when you’re automating a whole bunch of params in one shot…
I you’re talking auto completely off-line by hand/mouse, you have the line tool, which is able to draw quick & clean auto break points.
Not sure it covers what you’re asking for though…
