Class Synthesizer

java.lang.Object
  micromod.Synthesizer

public class Synthesizer

extends java.lang.Object

The Synthesizer represents a bunch of Modulators, each with an associated Channel. Methods are provided for setting up/updating the Modulators, and for extracting audio from the channels.

Method Summary

Channel	getChannel(int channel)
int	getCiaTickSamples()
int	getNumberOfChannels()
void	initialiseFX(int channel, int period, int instrument, int effectCommand, int effectValue) Call this method at the start of every row to assign instruments and initialise effects
boolean	isPAL()
void	reset() Silence the channels and reset panning to the default values.
void	setBPM(int bpm) Set the BPM of the playback (which directly affects the number of samples produced per tick of the CIA clock)
void	setModule(Module mod) Reconfigure the Synthesizer for a new module.
void	setSamplingRate(int rate) Set the Synthesizer to produce audio at the specified sampling rate.
void	updateFX() This method is called every tick except the first in a row to update the effect currently active on each channel.
void	usePAL(boolean p) Set whether to decode audio in PAL or NTSC mode.

Constructor Detail

Synthesizer

public Synthesizer(Module mod,
                   int mixingRate)

Constructor.

Parameters:

mod - The module to use initially.

mixingRate - The sampling rate.

Method Detail

setModule

public void setModule(Module mod)

Reconfigure the Synthesizer for a new module.

setSamplingRate

public void setSamplingRate(int rate)

Set the Synthesizer to produce audio at the specified sampling rate.

usePAL

public void usePAL(boolean p)

Set whether to decode audio in PAL or NTSC mode.

Parameters:

p - If true, use PAL pitch, else use NTSC pitch and tempo.

isPAL

public boolean isPAL()

Returns:

true if the Synthesizer is configured for PAL, otherwise NTSC

reset

public void reset()

Silence the channels and reset panning to the default values.

setBPM

public void setBPM(int bpm)

Set the BPM of the playback (which directly affects the number of samples produced per tick of the CIA clock)

getCiaTickSamples

public int getCiaTickSamples()

Returns:

The current number of samples of output per tick.

getNumberOfChannels

public int getNumberOfChannels()

Returns:

the number of channels the Synthesizer is configured for

getChannel

public Channel getChannel(int channel)

Returns:

The specified Channel object

initialiseFX

public void initialiseFX(int channel,
                         int period,
                         int instrument,
                         int effectCommand,
                         int effectValue)

Call this method at the start of every row to assign instruments and initialise effects

updateFX

public void updateFX()

This method is called every tick except the first in a row to update the effect currently active on each channel.
