Patchpublic class Patch extends Object A Patch object represents a location, on a MIDI
synthesizer, into which a single instrument is stored (loaded).
Every Instrument object has its own Patch
object that specifies the memory location
into which that instrument should be loaded. The
location is specified abstractly by a bank index and a program number (not by
any scheme that directly refers to a specific address or offset in RAM).
This is a hierarchical indexing scheme: MIDI provides for up to 16384 banks,
each of which contains up to 128 program locations. For example, a
minimal sort of synthesizer might have only one bank of instruments, and
only 32 instruments (programs) in that bank.
To select what instrument should play the notes on a particular MIDI
channel, two kinds of MIDI message are used that specify a patch location:
a bank-select command, and a program-change channel command. The Java Sound
equivalent is the
{@link MidiChannel#programChange(int, int) programChange(int, int)}
method of MidiChannel. |
