mandol

An emulation of a mandolin.

Syntax

ares mandol kamp, kfreq, kpluck, kdetune, kgain, ksize \
            [, ifn] [, iminfreq]

Initialization

ifn -- table number containing the pluck wave form. The file mandpluk.aiff is suitable for this. It is also available at ftp://ftp.cs.bath.ac.uk/pub/dream/documentation/sounds/modelling/.

iminfreq (optional, default=0) -- Lowest frequency to be played on the note. If it is omitted it is taken to be the same as the initial kfreq.

Performance

kamp -- Amplitude of note.

kfreq -- Frequency of note played.

kpluck -- The pluck position, in range 0 to 1. Suggest 0.4.

_kdetune _ -- The proportional detuning between the two strings. Suggested range 0.9 to 1.

kgain -- the loop gain of the model, in the range 0.97 to 1.

ksize -- The size of the body of the mandolin. Range 0 to 2.

Examples

Here is an example of the mandol opcode. It uses the file mandol.csd, and mandpluk.aiff.
