I've changed the subject line because the intention of my original post was to give the hard-pressed devs a bit of a lift, and this discussion is detracting from that. In the case of my recording, I would say that any latency is more likely to be a function of my playing live, and not being as good as I'd like to be! However, in general you are not comparing apples to apples. By their very nature many effects deliberately introduce delays in order to function. The most extreme example I know of is fast lookahead limiting. It side-chains a control signal then delays the main path (typically about 20mS) in order to apparently perform time travel and start to adjust the level before the spike hits. The integrated DAWS you get with Windows and Apple have default, fixed sets of effects that they know the precise conditions of and can therefore actually advance recorded tracks based on this precise knowledge. Try using unknown plugins and the situation changes. Without knowing the precise details of every effect you could plug in Rosegarden has no hope of doing this. In practice I've never found it a problem as it is easy to just jog a track left or right until it is correct. There is also a pseudo-latency effect you can get if you mix slow attack sounds with fast attack ones (something I do a lot of). I find that usually just one 'Jog Left' in the matrix viewer is enough - thank you very much whoever had that bright idea! -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.
