The dream of FM Synthesis is alive and well with the new Korg opsix Altered FM Synthesizer. The legendary instrument manufacturer is back with a synth that features six FM operators, 64 voices of polyphony, 42 on-board effects, a 16 step sequencer, a virtual patch bay, and much, much more.

Before we get into the opsix, let's talk a little about FM Synthesis. FM (short for Frequency Modulation) Synthesis is "additive synthesis," whereas traditional analog synthesizers use "subtractive synthesis." Traditional FM synthesizers utilize a simple starting wave to build up more complex sounds. They often get a bad reputation for being kind of laborious and menu-driven, but the opsix changes that.

Korg has made the opsix as user-friendly as possible by putting a knob at your fingertip for every function and giving you immediate access to 250 factory presets. To avoid menu scrolling, you can use the Favorites section, which doubles as a 16-step polyphonic sequencer, to save up to four banks of preset sounds.

We could talk all day long about the feature set of the Korg opsix Altered FM Synthesizer, but hearing is truly believing. Watch our demo below to learn more about everything going on with the opsix and get a taste test of the beautiful sounds this synthesizer is capable of bringing to your arsenal.
