[ardour-users] using effects, mainly eq

The latency is from the period settings you are using for jack.

I have found that EQing a track I have to use a similar setup to the way you are
using jack-rack then record the part/s to a new region.

It's also possible to use ardours automation but I have never found time to get
into it. If your computer is powerful eg  > 2.0mhz then automation should work
very well for your needs.

There is a document describing how to use automation but it is way outdated and
things may be done very differently now. Check the ardour documentation project
for that piece.

Or else someone here might give you up to date info.

 Being on stage with the band in front of crowds shouting, "Get off! No!
 We want normal music!", I think that was more like acting than anything
 I've ever done.
