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. * <p> * 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.
