## fmrhode

fmrhode — Uses FM synthesis to create a Fender Rhodes electric piano sound.

## Description

Uses FM synthesis to create a Fender Rhodes electric piano sound. It comes from a family of FM sounds, all using 4 basic oscillators and various architectures, as used in the TX81Z synthesizer.

## Syntax

    ares fmrhode kamp, kfreq, kc1, kc2, kvdepth, kvrate, ifn1, ifn2, \
          ifn3, ifn4, ivfn

## Initialization

All these opcodes take 5 tables for initialization. The first 4 are the basic inputs and the last is the low frequency oscillator (LFO) used for vibrato. The last table should usually be a sine wave.

The initial waves should be:

- ifn1 -- sine wave

- ifn2 -- sine wave

- ifn3 -- sine wave

- ifn4 -- fwavblnk.aiff

| Note
The file “fwavblnk.aiff” is also available at ftp://ftp.cs.bath.ac.uk/pub/dream/documentation/sounds/modelling/.

## Performance

kamp -- Amplitude of note.

kfreq -- Frequency of note played.

kc1, kc2 -- Controls for the synthesizer:

- kc1 -- Mod index 1

- kc2 -- Crossfade of two outputs

- Algorithm -- 5

kvdepth -- Vibrator depth

kvrate -- Vibrator rate

## Examples

Here is an example of the fmrhode opcode. It uses the file fmrhode.csd, and fwavblnk.aiff.
