Just in case anyone doesn't understand the '1/2 time' thing, what I mean is that if the regular beat goes;

Kick, snare, kick, snare.... the 1/2 time beat would be;
Kick, and , snare, and , Kick, and , snare, and........

thus slowing down the beat to half time, while the hi-hats stay mostly the same.

Probably in an arranger context, you could leave the accompaniment parts the same, and just have 1/2 time alternatives for drums and bass, and get a very useful variation on a basic groove.

Ideas.....?
