The Opsix, on the other hand, looks like a sound designers dream. There are six operators, with 21 waveforms, five different modes and they can be combined through 40 algorithms. Plus you can design custom user algorithms, as well. Then there’s a huge selection of effect for you to choose from, and you can combine up to three at a time. There’s three envelop generators, three LFOs and a 12 point virtual patch bay if you need to mix things up even more. And there’s a variable state filter with 11 different modes, including emulations of the MS-20 and Polysix.
