In the provinces, smaller gamelans tend to be Slendro only. In the old courts, or when subsidized by the local rich man, they will have both systems, which are never mixed. Slendro instruments usually face the audience, Pelog are set at 90 degrees. Slendro and Pelog always have one tone in common-- when you switch from one to the other, you bang on the common tone for a while, then turn and start playing on the other set. A very dramatic change in tonality. In the 70s, when I was just getting Indonesianized, there were like 3 gamelans in the entire US-- UCal, UMich, and Wesleyan (CT). My major prof's wife, Judith Becker, was and still is the director of the UM gamelan. A beautiful matched set of instruments in both tunings, and a very professional group.
