st2pitch	Abstraction		Accumulates incoming intervals and outputs pitch classes Accumulates incoming intervals and outputs pitch classes (i.e. notes without register information) at the left outlet resp. notes (= MIDI note numbers) at the right outlet.
TimeLagAccumulator	Patch		A replica of the San Francisco Tape Music Center "Time Lag Accumulator" A replica of the San Francisco Tape Music Center "Time Lag Accumulator," hereafter referred to as TLA, because of the inherent joke, and because of impending repetitive stress issues. The TLA was originally a long tape delay scheme used by Terry Riley, Pauline Oliveros and others at the San Francisco Tape Music Center. It involved a couple of well calibrated tape recorders, one to record onto, and the other placed some distance away for playback. This same basic scheme was later utilized by Fripp & Eno, and forms the basis of "Frippertronics."
v.+=	External		v.+= accumulates input pixel values. v.+= accumulates input pixel values. The accumulators are the same component size as the incoming streams and the result is clipped to the maximum value expressible by that component size, so in most cases it is desirable to use a v.float32 or v.int32 prior to the v.+= in order to have accumulated sums of larger values.
v.bounds	External		v.bounds calculates the bounding rectangle of the non-black areas of the image. v.bounds calculates the bounding rectangle of the non-black areas of the image. It has some features to improve its performance where there might be bits of noise outside the area of maximum concentration. v.bounds finds the top- and bottom-most lines and left- and right-most columns such that noise_tolerance amount of the image mass is outside the defined bounds. In other words, if noise_tolerance is 0.1, then the starting value for the top will be the line in which the accumulated total of pixel values becomes larger than 0.1 times the total sum of all pixel values in the image. From this initial bounding rectangle, v.bounds works backwards, expanding to include consecutive lines or columns which have at least noise_threshold total pixel value. This tends t
v.regions	External		v.regions allows you to draw or otherwise define regions within the stream. v.regions allows you to draw or otherwise define regions within the stream. There are several ways that these regions can be used. Accumulating stream pixel data into region accumulators: v.regions will sum all pixels brightnesses for each region and provide this information in a list for further processing in MAX.
