discoDSP OPL FM Synth

The OPL is a digital Synthesizer that emulates the iconic Yamaha YM3812 sound chip sound that you can also find in old soundcards (AdLib, SoundBlaster…). It basically emulates the provides all the features of the OPL2 and some of the OPL3 chips.

Background info: The plugin was originally coded by Bruce Sutherland, but discoDSP created a macOS version and an iOS version with AUv3 support.

On the synthesis, it works with channels where each channel has two oscillators capable of generating eight different waveforms, including sine, half sine, absolute sine, quarter sine, camel sine, square, and logarithmic sawtooth. Then it hosts a modulator and carrier section, which we know from classic FM synths.

Each section has identical controls: selectable waveforms, an ADSR envelope, and controls for vibrato, tremolo, sustain, and key scale envelope rate. Additionally, you can adjust the velocity sensitivity.

Further, you can tweak the depth of the tremolo/vibrato effects, switch between FM or additive algorithms, percussion modes, and the ability to load SBI files. There are five handy percussion modes, including bass drum, snare, tom, cymbal, and hi-hat.

OPL is certainly not the most classic FM Synthesizer you can get. So if you are looking for a dirty and characterful FM synth with a bit of nostalgia, this could be interesting for you.
