Description

The OPLoid adopts the synthesis principles of the Yamaha YM3812 (OPL2) and YMF262 (OPL3) FM chips. These chips were widely used on IBM PC-based sound cards in the late 20th century (e.g., AdLib and Soundblaster) and defined the sound of the "MS-DOS era".

The OPLoid is not an accurate emulation of the OPL 2 or 3, but rather a synthesizer on its own. It closely mimics the OPL 2 and 3 in their principles of operation to stay true to the original chips' characteristic sound and to make it accessible in a modern music production environment. Nevertheless, some parameters have been slightly modified to allow for more flexibility in sound design.

While the OPLoid might be useful for all genres of electronic music, it is probably especially suitable for Vaporwave, Dungeon Synth and Chiptune.

Features:

- close imitation of the 2-operator FM algorithm from the Yamaha OPL2 and OPL3 sound chips

- 8 waveforms

- monophonic and polyphonic mode

- up to 64 voices of polyphony (depending on CPU power)

- 4 LFOs (vibrato, tremolo, FM depth, panorama)

- pitchbend and modwheel support (up to 6 parameters independently mappable to modwheel)

- 195 factory presets

- cloud patch database for sharing patches among users

Version 0.2.7 comes with improved envelopes and new preset patches.
