SPLITTER(outsk, insk, dur, GLOBAL_AMP, input_channel, OUTCHAN0_AMP, OUTCHAN1_AMP, …)
CAPITALIZED parameters are pfield-enabled for table or dynamic control (see the maketable or makeconnection scorefile commands). Parameters after the [bracket] are optional and default to 0 unless otherwise noted.
| Param Field | Parameter | Units | Dynamic | Optional | Notes |
|---|---|---|---|---|---|
| p0 | output start time | seconds | no | no | |
| p1 | input start time | seconds | no | no | |
| p2 | duration | seconds | no | no | |
| p3 | global amp multiplier | relative multiplier of input signal | yes | no | |
| p4 | input channel | - | no | no | |
| p5-pN | amplitude multiplier for each output channel | relative multiplier | yes | no |
Parameters labled as Dynamic can receive dynamic updates from a table or real-time control source.

SPLITTER is a utility istrument for routing signals into the different RTcmix busses (and outputs).
SPLITTER does essentially the opposite that the MIX instrument does, with an added amplitude multiplier for each output channel in the output matrix. The number of outputs is set by the bus_config scorefile command.
SPLITTER is necessary for setting up parallel processing chains, where the signal originating from one instrument or input is intended to be routed through several seperate processing chains simultaneously.
very basic:
rtsetparams(44100, 2)
load("WAVETABLE")
load("SPLITTER")
dur = 10
amp = 5000
freq = 440
bus_config("WAVETABLE", "aux 0 out")
WAVETABLE(0, dur, amp, freq)
bus_config("WAVETABLE", "aux 1 out")
freq = 770
WAVETABLE(0, dur, amp, freq)
bus_config("SPLITTER", "aux 0 in", "aux 10 out", "aux 12 out")
inchan = 0
SPLITTER(0, 0, dur, 1, inchan, 1, 1)
bus_config("SPLITTER", "aux 1 in", "aux 11 out", "aux 13 out")
SPLITTER(0, 0, dur, 1, inchan, 1, 1)
//bus_config("MIX", "aux 10-11 in", "out 0-1")
bus_config("MIX", "aux 12-13 in", "out 0-1")
MIX(0, 0, dur, 1, 0, 1)
slightly more advanced:
rtsetparams(44100, 2)
load("STRUM2")
load("FLANGE")
load("PANECHO")
load("SPLITTER")
bus_config("STRUM2", "aux 0-1 out")
bus_config("SPLITTER", "aux 0-1 in", "aux 2-3 out", "aux 4-5 out")
bus_config("MIX", "aux 2-3 in", "out 0-1")
bus_config("FLANGE", "aux 4-5 in", "aux 6-7 out")
bus_config("PANECHO", "aux 6-7 in", "out 0-1")
