Korg opsix FM Synth Review
The opsix is a powerful little FM based synth from Korg that sounds really good. Korg has made FM programming accessible with the opsix. They've included many of the iconic key and bell sounds you'll recognize from the DX-7 days but that's just a fraction of what the opsix is capable of. The presets are so good. Come for the built-in sounds, stay for the addition to discovery.
After downloading the 2.0 update we were impressed by many of the new presets that are complex patches that sound really good. With or without the built-in effects of the opsix the instruments you can create are very musical.
We love the way the opsix pairs with something like a subsequent 37. It's just the right combination of analog and FM we like. We found ourselves firing up the opsix more and more to simply explore the sounds and tweak the faders and knobs to see what we could come up with. We don't remember FM being this fun with the DX-7.
The opsix is cheaply made and does not inspire confidence upon unboxing. It's a lot of plastic with a really cheap keybed and, well, it's a lot of cheap plastic. We feel we could accidentally damage any of the various in/out jacks on the back of opsix easily. The main controls, knobs and faders are fine and we also love the way the opsix looks. It photographs really well. But it's really cheaply made. The BOM or bill of materials must be really low on this sucker. So kudos to Korg for making what we imagine is a fairly profitable unit at scale.
So yeah, it's cheaply made and we would have liked a much better keybed. However, what counts is the sound and the opsix sounds great. It really does. The built-in effects are really good and it pairs nicely with outboard gear too. At times, we simply forgot we were playing an FM based synth. It's that good. It's not just bells and biting sounds. The opsix can do warm pads, poly sizzle, and interesting atmospheric sounds as well. It's an extremely versatile synth and would be a great first synth to learn what FM can do.
Would be nice to see Korg release a sound module version of the opsix unless they plan on doing a better versions with a proper keybed with a much better feel and aftertouch...etc. For users where this is not their primary keyboard this isn't an issue. However, it wouldn't take much much to improve the keybed for the opsix plus.
