REQ: DiscoDSP OPL FM Synthesizer V2.2 WIN/MAC

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.

OVERVIEW

This instrument provides an emulated OPL sound chip. It provides all features of the OPL2, and some features of the OPL3.

Native Apple Silicon compatibility (M1 or higher).

What's an OPL?
At a technical level: the emulator has channels comprised of 2 oscillators each. Each pair of oscillators is usually combined via phase modulation (basically frequency modulation). Each oscillator can produce one of eight waveforms (sine, half sine, absolute sine, quarter sine, alternating sine, camel sine, square, logarithmic sawtooth), and has an ADSR envelope controlling its amplitude. The unusual waveforms give it a characteristic sound.

How do I use it?
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.
