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.

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)

- Scala (.scl) tuning support

- 195 factory presets
