However, * <code>MidiChannel</code> adds some "get" methods that retrieve the value * most recently set by one of the standard MIDI channel messages. Similarly, * methods for per-channel solo and mute have been added. * <p> * A <code>{@link Synthesizer}</code> object has a collection * of <code>MidiChannels</code>, usually one for each of the 16 channels * prescribed by the MIDI 1.0 specification. The <code>Synthesizer</code> * generates sound when its <code>MidiChannels</code> receive * <code>noteOn</code> messages. * <p> * See the MIDI 1.0 Specification for more information about the prescribed * behavior of the MIDI channel messages, which are not exhaustively * documented here. The specification is titled <code>MIDI Reference: * The Complete MIDI 1.0 Detailed Specification</code>, and is published by * the MIDI Manufacturer's Association (<a href = http://www.midi.org> * http://www.midi.org</a>). * <p> * MIDI was originally a protocol for reporting the gestures of a keyboard * musician. This genesis is visible in the <code>MidiChannel</code> API, which * preserves such MIDI concepts as key number, key velocity, and key pressure. * It should be understood that the MIDI data does not necessarily originate * with a keyboard player (the source could be a different kind of musician, or * software). Some devices might generate constant values for velocity * and pressure, regardless of how the note was performed. * Also, the MIDI specification often leaves it up to the * synthesizer to use the data in the way the implementor sees fit. For * example, velocity data need not always be mapped to volume and/or brightness. * * @see Synthesizer#getChannels * * @author David Rivas * @author Kara Kytle */ public interface MidiChannel { /** * Starts the specified note sounding.

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. * <p> * Controllers 64 through 95 (0x40 - 0x5F) allow 7-bit precision. * The value of a 7-bit controller is set completely by the * <code>value</code> 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.
