If I'm not mistaken, the Phantom S uses a loop sequencer similar to the XP boards (called RPS). As I remember, this discussion Squeak is continuing stems from an earlier thread where we lamented the absence of a loop seq. on arrangers. To make my point again, synth loop sequencers are good, but require that you plan ahead and probably pre-record your loops. What arrangers need is a looper that will record a style and some chord changes LIVE.
