## moog

moog — An emulation of a mini-Moog synthesizer.

## Description

An emulation of a mini-Moog synthesizer.

## Syntax

    ares moog kamp, kfreq, kfiltq, kfiltrate, kvibf, kvamp, iafn, iwfn, ivfn

## Initialization

iafn, iwfn, ivfn -- three table numbers containing the attack waveform (unlooped), the main looping wave form, and the vibrato waveform. The files mandpluk.aiff and impuls20.aiff are suitable for the first two, and a sine wave for the last.

| Note
The files “mandpluk.aiff” and “impuls20.aiff” are also available at ftp://ftp.cs.bath.ac.uk/pub/dream/documentation/sounds/modelling/.

## Performance

kamp -- Amplitude of note.

kfreq -- Frequency of note played.

kfiltq -- Q of the filter, in the range 0.8 to 0.9

kfiltrate -- rate control for the filter in the range 0 to 0.0002

kvibf -- frequency of vibrato in Hertz. Suggested range is 0 to 12

kvamp -- amplitude of the vibrato

## Examples

Here is an example of the moog opcode. It uses the file moog.csd, mandpluk.aiff, and impuls20.aiff.
