RedMst, RedTrk, RedTrk2 and RedSeq are a set of supercollider classes that i now finally cleaned up and released. i wrote them about a year ago and have been using them for live performances since then. they function as sort of a timeline and the basic idea is to sequence code in a very simple way.
the master keeps track of when some tracks should play and then switches them on/off with .play and .stop at the right time (next quant beat, default= 4). a track can be any code that responds to these two messages (pbind, bbcut2, pdef, routines, etc).

redMst is distributed as a quark. see Quarks helpfile for more info on how to install.
