public class Patch extends Object
Patchobject represents a location, on a MIDI synthesizer, into which a single instrument is stored (loaded). Every
Instrumentobject has its own
Patchobject 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
programChange(int, int) method of
