Description

Uses FM synthesis to create a percussive flute 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 fmpercfl 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. These all default to a sine wave table.

The initial waves should be:

Performance

kamp -- Amplitude of note.

kfreq -- Frequency of note played.

kc1, kc2 -- Controls for the synthesizer:

kvdepth -- Vibrator depth

kvrate -- Vibrator rate
