I tried this with a style called 'bachat2' and it worked pretty well.

Create a test song 8 bars long.

In bar 7 use F5 to enter a tempo double the regular one. Each quarter note will sound like an eighth.

Enter "C..,C.." for the first half of bar 7. Note the comma.

Enter 'C...' as the only chord in bar 8

Sounded OK with this style. Might sound really badly with other styles. Try using F5 to make some of the instruments sit out on some of the shots.
