I already have too much hardware... but what I didn't have is a FM synth. And now I have.

When it comes to FM synths there's a fair bit of choice but one synth that really gets nice and hands on is the Korg Opsix (an alternative would be the Twisted Electrons MegaFM, but I strongly dislike mini-sliders). And the Opsix does a lot more than just FM, so it seemed like a good flexible option.

Let's dive into it! Part 1 will focus a bit more on general controls and some top level stuff. In part 2 we'll explorer the mod-matrix, sequencer and arpeggiator.
