Accents in Sequencing

Yeh, that's the quick-n-dirty method. Ctl-click on each downbeat and drag them all up together.

Of course, what you'll end up with will still sound artificial and boring, but it's a start. Try to mix it up a little as you go.

You don't say what kind of a performance it is, but one way to add interest to a sequenced part is to apply aggressive note thinning at the start and let it get busier as the song progresses. For a bass part, for example, remove some of the short notes and stretch the others. Same trick works for kick drums and ride cymbals. This way, you can start with a simple repetitive sequence that doesn't sound so repetitive over the course of the song.

Keep in mind that increasing velocity usually affects tone as well as volume. Another trick is to lower the velocities across the board for the first verses and then raise them all during the chorus. This will make the part both louder and brighter during the chorus, enhancing song dynamics and making it all less boring.

Hey thanks for your response bitflipper, you've been very helpful with every question I have asked so far, so many thanks. I still have a couple of things I would like cleared up. When you talk about note thinning, do you mean alter the durations of the MIDI notes or just the velocities? I now understand that velocity also affects tone, is this something to be considered from a mixing point of view and an arranging point of view? Does increasing the volume on the audio track have the same effect on tone? Thanks in advance, and if I haven't made myself clear or if I am not making any sense, let's say I am inexperienced yet eager to learn.
