I would like to suggest modern progressive rock styles sometimes referred to as Math Rock. Polyphia is an example of cutting-edge technical musicianship in a genre expanding style. Although these styles typically use guitars and traditional drums they are augmented with contemporary backings and sometimes hip-hop elements. These would also lend themselves to midi allowing a much larger sound palette than is typical of most PG Music Realtracks which limit the user to mostly traditional instruments.

Here is an example of Polyphia:
