discoDSP OPL emulates the Yamaha OPL2 (1985) — the FM chip behind AdLib and Sound Blaster game soundtracks of the late 80s and early 90s. Two-operator FM with eight waveforms per operator, OPL2 percussion mode, and partial OPL3 features. 16x oversampling, 2000+ presets, SBI import.
Overview
Emulates the OPL2 in full and a subset of OPL3 features. Imports SBI presets (Creative Labs' instrument format for Sound Blaster cards) — drag-and-drop into the plugin.
Each channel is two operators (carrier + modulator) using phase modulation (FM-equivalent). Eight per-operator waveforms: sine, half sine, absolute sine, quarter sine, alternating sine, camel sine, square, logarithmic sawtooth. ADSR per operator. The waveform set is what makes OPL sound like OPL — sine alone won't get you there.
Percussion mode adds bass drum, snare, tom, cymbal, and hi-hat, each tied to specific operator slots and waveforms.
