STKMandolin — STKMandolin produces mamdolin-like sounds.
STKMandolin produces mamdolin-like sounds, using "commuted synthesis" techniques to model a mandolin instrument.
asignal STKMandolin ifrequency, iamplitude, [kc1, kv1[, kc2, kv2[, kc3, kv3[, kc4, kv4[, kc5, kv5]]]]]
ifrequency -- Frequency of note played, in Hertz.
iamplitude -- Amplitude of note played (range 0-1).
kc1, kv1, kc2, kv2, kc3, kv3, kc4, kv4, kc5, kv5, kc6, kv6, kc7, kv7, kc8, kv8 -- Up to 8 optional k-rate controller pairs for the STK opcodes. Each controller pair consists of a controller number (kc) followed by a controller value (kv). The 5 controller numbers and values that work for STKMandolin are:
kc, kv -- 2, size of body.
kc, kv -- 4, pluck position.
kc, kv -- 11, string sustain.
kc, kv -- 1, string detuning.
kc, kv -- 128, position of microphone.

The code for this opcode is taken directly from the Mandolin class in the Synthesis Toolkit in C++ by Perry R. Cook and Gary P. Scavone. More on the STK classes can be found here: https://ccrma.stanford.edu/software/stk/classes.html |
Here is an example of the STKMandolin opcode. It uses the file STKMandolin.csd, and mandpluck.aiff.
