EV = the rhythm is based on notes that have an evenly spaced time
EV8 = the instruments and drums use an evenly spaced time based on 1/8th notes.
EV16 = the instruments and drums use an evenly spaced time based on 1/16th notes.

SW = styles based on a swing feel
SW8 = the instruments and drums have a swing feel based on 1/8th triplets.
SW16 = the instruments and drums have a swing feel based on 1/16th triplets.

Generally, EV styles and SW styles do not mix too well. If you have a drum beat that is an EV style, it's best to choose instruments that are EV styles. Likewise, if you have a drum beat that's a SW style, it's best that the instruments also are SW styles.
