The OPL is a digital sound synthesis chip developed by Yamaha in the mid 1980s. Among other products, it was used in sound cards for PC, including the Ad Lib card and early Sound Blaster series.
This instrument provides an emulated OPL sound chip. It provides all features of the OPL2, and some features of the OPL3. More than 2000 presets are included.
Each instance of the plugin emulates an entire OPL chip, but with this plugin, essentially you are just working with two operators: the carrier and modulator.
Standalone app requires MIDI keyboard.
