New instrument object and functions #54

Closed DhrBaksteen closed 4 years ago

DhrBaksteen commented 4 years ago

This change adds a simpler way of defining OPL2 instruments in code to the library

New instrument functions:

createInstrument - Creates a new empty instruement
loadInstrument - Loads a predefined melodic or drum imstrument
getInstrument - Creates a new melodic instrument from the given OPL2 channel's current settings
setInstrument - Set an instrument to an OPL2 channel with optional volume
getDrumInstrument - Creates a new drum instrument from the current OPL2 drum settigns
setDrumInstrument - Set a drum instrument to its precussive channel

This fixes the following issues:

44 Cracking noises in MIDI output

47 SetInstrument does not support SRAM instruments

Examples have been updated to take advantage of the new instrument struct and functions.
