One thought on “Korg OPSIX – review, tutorial and 10 patch ideas

  1. No mention of the Midi implementation – sysex or just a couple of CCs like the Wavestate?
    I sure hope it is better than the Wavestate. That synth is great but after the initial gloss wears off, it feels a ‘less than a pro’ machine not being able to get to the ‘insides’ via Midi.
    The OPSIX FM mixer and encoders looks like a useful way to edit FM. I trust it isn’t like the DX7 in that you don’t have to re-strike a key to hear changes (much like the Montage/MODX)?
