MSITAR(outsk, dur, AMP, FREQ, plamp[, PAN, AMPENV])
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 | duration | seconds | no | no | |
| p2 | amplitude | absolute, for 16-bit soundfiles: 0-32768 | yes | no | |
| p3 | frequency | Hz | yes | no | |
| p4 | pluck amp | 0.0-1.0 | no | no | |
| p5 | pan | 0-1 stereo; 0.5 is middle | yes | yes | default: 0.5 |
| p6 | amplitude envelope | reference to a pfield table-handle | yes | yes | default: 1.0 |
Parameters labled as Dynamic can receive dynamic updates from a table or real-time control source.

MSITAR the “Sitar” physical model in Perry Cook and Gary Scavone’s STK, the Synthesis ToolKit.
MSITAR models an Indian sitar. It uses a modified Karplus-Strong (“plucked string” – see the STRUM2 instrument) algorithm. Here’s what Perry says about “Sitar”:
The amplitude envelope table (p6, “AMPENV”) is an optional parameter. It is also redundant – the same functionality can be achieved by using a pfield-table reference in p2 (“AMP”).
MSITAR can produce other mono or stereo output.
very basic:
rtsetparams(44100, 1)
load("MSITAR")
amp = 17000
MSITAR(0, 3.5, amp, cpspch(8.00), 0.9)
MSITAR(4, 3.5, amp, cpspch(8.07), 0.9)
slightly more advanced:
rtsetparams(44100, 2)
load("MSITAR")
MSITAR(0, 3.5, 30000, cpspch(8.00), 0.9)
amp = maketable("line", 1000, 0,0, 1,1, 2,0)
freq = makerandom("linear", 9.0, cpspch(8.065), cpspch(8.075))
MSITAR(4, 3.5, amp*20000, freq, 0.9, 0.0)
freq = makerandom("linear", 7.0, cpspch(8.065), cpspch(8.075))
MSITAR(4, 3.5, amp*20000, freq, 0.9, 1.0)
stramp = maketable("line", 1000, 0,1, 2,0)
pan = makeLFO("sine", 14, 0, 1)
MSITAR(8, 3.5, 20000, cpspch(7.07), 0.9, pan, stramp)
