Implements javax.sound.midi.MidiChannel.allNotesOff.

Doc from javax.sound.midi.MidiChannel.allNotesOff.

Turns off all notes that are currently sounding on this channel. The notes might not die away instantaneously; their decay rate is determined by the internals of the Instrument. If the Hold Pedal controller (see controlChange) is down, the effect of this method is deferred until the pedal is released.

Implements javax.sound.midi.MidiChannel.controlChange.

Doc from javax.sound.midi.MidiChannel.controlChange.

Reacts to a change in the specified controller's value. A controller is some control other than a keyboard key, such as a switch, slider, pedal, wheel, or breath-pressure sensor. The MIDI 1.0 Specification provides standard numbers for typical controllers on MIDI devices, and describes the intended effect for some of the controllers. The way in which an Instrument reacts to a controller change may be specific to the Instrument.

The MIDI 1.0 Specification defines both 7-bit controllers and 14-bit controllers. Continuous controllers, such as wheels and sliders, typically have 14 bits (two MIDI bytes), while discrete controllers, such as switches, typically have 7 bits (one MIDI byte). Refer to the specification to see the expected resolution for each type of control.

Controllers 64 through 95 (0x40 - 0x5F) allow 7-bit precision. The value of a 7-bit controller is set completely by the value argument. An additional set of controllers provide 14-bit precision by using two controller numbers, one for the most significant 7 bits and another for the least significant 7 bits. Controller numbers 0 through 31 (0x00 - 0x1F) control the most significant 7 bits of 14-bit controllers; controller numbers 32 through 63 (0x20 - 0x3F) control the least significant 7 bits of these controllers. For example, controller number 7 (0x07) controls the upper 7 bits of the channel volume controller, and controller number 39 (0x27) controls the lower 7 bits. The value of a 14-bit controller is determined by the interaction of the two halves. When the most significant 7 bits of a controller are set (using controller numbers 0 through 31), the lower 7 bits are automatically set to 0. The corresponding controller number for the lower 7 bits may then be used to further modulate the controller value.

It is possible that the underlying synthesizer does not support a specific controller message. In order to verify that a call to controlChange was successful, use getController.

Implements javax.sound.midi.MidiChannel.getChannelPressure.

Doc from javax.sound.midi.MidiChannel.getChannelPressure.

Obtains the channel's keyboard pressure.

If the device does not support setting channel pressure, this method always returns 0. Calling setChannelPressure will have no effect then.

Annotations

@Override

Implements javax.sound.midi.MidiChannel.getController.

Doc from javax.sound.midi.MidiChannel.getController.

Obtains the current value of the specified controller. The return value is represented with 7 bits. For 14-bit controllers, the MSB and LSB controller value needs to be obtained separately. For example, the 14-bit value of the volume controller can be calculated by multiplying the value of controller 7 (0x07, channel volume MSB) with 128 and adding the value of controller 39 (0x27, channel volume LSB).

If the device does not support setting a specific controller, this method returns 0 for that controller. Calling controlChange will have no effect then.

Annotations

@Override

Implements javax.sound.midi.MidiChannel.getMono.

Doc from javax.sound.midi.MidiChannel.getMono.

Obtains the current mono/poly mode. Synthesizers that do not allow changing mono/poly mode will always return the same value, regardless of calls to setMono.

Annotations

@Override

Implements javax.sound.midi.MidiChannel.getMute.

Doc from javax.sound.midi.MidiChannel.getMute.

Obtains the current mute state for this channel. If the underlying synthesizer does not support muting this channel, this method always returns false.

Annotations

@Override

Implements javax.sound.midi.MidiChannel.getOmni.

Doc from javax.sound.midi.MidiChannel.getOmni.

Obtains the current omni mode. Synthesizers that do not allow changing the omni mode will always return the same value, regardless of calls to setOmni.

Annotations

@Override

Implements javax.sound.midi.MidiChannel.getPitchBend.

Doc from javax.sound.midi.MidiChannel.getPitchBend.

Obtains the upward or downward pitch offset for this channel. If the device does not support setting pitch bend, this method always returns 8192. Calling setPitchBend will have no effect then.

Annotations

@Override

Implements javax.sound.midi.MidiChannel.getPolyPressure.

Doc from javax.sound.midi.MidiChannel.getPolyPressure.

Obtains the pressure with which the specified key is being depressed.

If the device does not support setting poly pressure, this method always returns 0. Calling setPolyPressure will have no effect then.

@Override

Implements javax.sound.midi.MidiChannel.getSolo.

Doc from javax.sound.midi.MidiChannel.getSolo.

Obtains the current solo state for this channel. If the underlying synthesizer does not support solo on this channel, this method always returns false.

Annotations

@Override

Implements javax.sound.midi.MidiChannel.localControl.

Doc from javax.sound.midi.MidiChannel.localControl.

Turns local control on or off. The default is for local control to be on. The "on" setting means that if a device is capable of both synthesizing sound and transmitting MIDI messages, it will synthesize sound in response to the note-on and note-off messages that it itself transmits. It will also respond to messages received from other transmitting devices. The "off" setting means that the synthesizer will ignore its own transmitted MIDI messages, but not those received from other devices.

It is possible that the underlying synthesizer does not support local control. In order to verify that a call to localControl was successful, check the return value.

@Override

Implements javax.sound.midi.MidiChannel.noteOff.

Doc from javax.sound.midi.MidiChannel.noteOff.

Turns the specified note off. The key-up velocity, if not ignored, can be used to affect how quickly the note decays. In any case, the note might not die away instantaneously; its decay rate is determined by the internals of the Instrument. If the Hold Pedal (a controller; see controlChange) is down, the effect of this method is deferred until the pedal is released.

@Override

Implements javax.sound.midi.MidiChannel.noteOn.

Doc from javax.sound.midi.MidiChannel.noteOn.

Starts the specified note sounding. The key-down velocity usually controls the note's volume and/or brightness. If velocity is zero, this method instead acts like noteOff(int), terminating the note.

Implements javax.sound.midi.MidiChannel.programChange.

Doc from javax.sound.midi.MidiChannel.programChange.

Changes a program (patch). This selects a specific instrument from the currently selected bank of instruments.

The MIDI specification does not dictate whether notes that are already sounding should switch to the new instrument (timbre) or continue with their original timbre until terminated by a note-off.

The program number is zero-based (expressed from 0 to 127). Note that MIDI hardware displays and literature about MIDI typically use the range 1 to 128 instead.

It is possible that the underlying synthesizer does not support a specific program. In order to verify that a call to programChange was successful, use getProgram.

Annotations

@Override

Implements javax.sound.midi.MidiChannel.programChange.

Doc from javax.sound.midi.MidiChannel.programChange.

Changes the program using bank and program (patch) numbers.

It is possible that the underlying synthesizer does not support a specific bank, or program. In order to verify that a call to programChange was successful, use getProgram and getController. Since banks are changed by way of control changes, you can verify the current bank with the following statement:

  int bank = (getController(0) * 128) + getController(32);

@Override

Implements javax.sound.midi.MidiChannel.setChannelPressure.

Doc from javax.sound.midi.MidiChannel.setChannelPressure.

Reacts to a change in the keyboard pressure. Channel pressure indicates how hard the keyboard player is depressing the entire keyboard. This can be the maximum or average of the per-key pressure-sensor values, as set by setPolyPressure. More commonly, it is a measurement of a single sensor on a device that doesn't implement polyphonic key pressure. Pressure can be used to control various aspects of the sound, as described under setPolyPressure.

It is possible that the underlying synthesizer does not support this MIDI message. In order to verify that setChannelPressure was successful, use getChannelPressure.

@Override

Implements javax.sound.midi.MidiChannel.setMono.

Doc from javax.sound.midi.MidiChannel.setMono.

Turns mono mode on or off. In mono mode, the channel synthesizes only one note at a time. In poly mode (identical to mono mode off), the channel can synthesize multiple notes simultaneously. The default is mono off (poly mode on).

"Mono" is short for the word "monophonic," which in this context is opposed to the word "polyphonic" and refers to a single synthesizer voice per MIDI channel. It has nothing to do with how many audio channels there might be (as in "monophonic" versus "stereophonic" recordings).

It is possible that the underlying synthesizer does not support mono mode. In order to verify that a call to setMono was successful, use getMono.

Annotations

@Override

Implements javax.sound.midi.MidiChannel.setMute.

Doc from javax.sound.midi.MidiChannel.setMute.

Sets the mute state for this channel. A value of true means the channel is to be muted, false means the channel can sound (if other channels are not soloed).

Unlike allSoundOff(), this method applies to only a specific channel, not to all channels. Further, it silences not only currently sounding notes, but also subsequently received notes.

It is possible that the underlying synthesizer does not support muting channels. In order to verify that a call to setMute was successful, use getMute.

Annotations

@Override

Implements javax.sound.midi.MidiChannel.setOmni.

Doc from javax.sound.midi.MidiChannel.setOmni.

Turns omni mode on or off. In omni mode, the channel responds to messages sent on all channels. When omni is off, the channel responds only to messages sent on its channel number. The default is omni off.

It is possible that the underlying synthesizer does not support omni mode. In order to verify that setOmni was successful, use getOmni.

Annotations

@Override

Implements javax.sound.midi.MidiChannel.setPitchBend.

Doc from javax.sound.midi.MidiChannel.setPitchBend.

Changes the pitch offset for all notes on this channel. This affects all currently sounding notes as well as subsequent ones. (For pitch bend to cease, the value needs to be reset to the center position.)

The MIDI specification stipulates that pitch bend be a 14-bit value, where zero is maximum downward bend, 16383 is maximum upward bend, and 8192 is the center (no pitch bend). The actual amount of pitch change is not specified; it can be changed by a pitch-bend sensitivity setting. However, the General MIDI specification says that the default range should be two semitones up and down from center.

It is possible that the underlying synthesizer does not support this MIDI message. In order to verify that setPitchBend was successful, use getPitchBend.

Annotations

@Override

Implements javax.sound.midi.MidiChannel.setPolyPressure.

Doc from javax.sound.midi.MidiChannel.setPolyPressure.

Reacts to a change in the specified note's key pressure. Polyphonic key pressure allows a keyboard player to press multiple keys simultaneously, each with a different amount of pressure. The pressure, if not ignored, is typically used to vary such features as the volume, brightness, or vibrato of the note.

It is possible that the underlying synthesizer does not support this MIDI message. In order to verify that setPolyPressure was successful, use getPolyPressure.

Annotations

@Override

Implements javax.sound.midi.MidiChannel.setSolo.

Doc from javax.sound.midi.MidiChannel.setSolo.

Sets the solo state for this channel. If solo is true only this channel and other soloed channels will sound. If solo is false then only other soloed channels will sound, unless no channels are soloed, in which case all unmuted channels will sound.

It is possible that the underlying synthesizer does not support solo channels. In order to verify that a call to setSolo was successful, use getSolo.
