trcross trcross trcross Streaming partial track cross-synthesis. The trcross opcode takes two inputs containg TRACKS pv streaming signals (as generated, for instance by partials) and cross-synthesises them into a single TRACKS stream. Two different modes of operation are used: mode 0, cross-synthesis by multiplication of the amplitudes of the two inputs and mode 1, cross-synthesis by the substititution of the amplitudes of input 1 by the input 2. Frequencies and phases of input 1 are preserved in the output. The cross-synthesis is done by matching tracks between the two inputs using a 'search interval'. The matching algorithm will look for tracks in the second input that are within the search interval around each track in the first input. This interval can be changed at the control rate. Wider search intervals will find more matches. fsig trcross fin1, fin2, ksearch,kdepth[,kmode] fsig -- output pv stream in TRACKS format fin1 -- first input pv stream in TRACKS format. fin2 -- second input pv stream in TRACKS format ksearch -- search interval ratio, defining a 'search area' around each track of 1st input for matching purposes. kdepth -- depth of effect (0-1). kmode -- mode of cross-synthesis. 0, multiplication of amplitudes (filtering), 1, subsitution of amplitudes of input 1 by input 2 (akin to vocoding).
