Trying to update the firmware here. It's on 1.01.
There's no USB Network item in the SYS menu so I'm stuck. What can I do?

Ok. Did it.
The japanese Korg System Updater manual is in error. It says you have to set RNDIS in the globals if you're on lower than 3.0. It refers you to the instructions on page3, but those instructions tell you to set USB Network to RNDIS and that setting doesn't exist in 1.01. I just ignored that step and it went fine.

Glad you got it sorted. i believe the system update software is much newer, post1.0 firmware. It’s a lot simpler to use in the end though!

Hey OpSixers - I just got my MKII out of the box.

Just going through the presets here... for the OPs, as is known, carriers are Red LEDs and mods are Bluish-Purple LEDs.

BUT, I'm also seeing some that are nearly white (couldn't capture this via my phone camera, but it's definitely a dim, white-ish color). Notably preset 101, Operator 1 & preset 132 Operator 4, as examples.

On top of that, I've seen a few that are more like a normal purple, not the usual bluish-purple mix. Preset 168 Operator 3. (pic attached) Also preset 180 Operators 1-5.


Also, while holding SHIFT to use the faders as adjustments, for most patches, as expected, everything turns green. However, there's a few that turn yellow? (pic attached)

Does anyone else have this? At first I thought maaaaybe it was the adjacent LEDs affecting the hue, but nope... on most other patches it sticks to the red & bluish-purples just fine.

I've gone through the provided manual sheet & googled, but I've come up with ... nothing.

As far as I can tell, the adjustment (waveform) whether green or yellow is the same thing?

Surely these colors denote something? A thousand pardons if this has already been gone over....

(PICS COMING... had trouble uploading)

Here are the pics...

Yep. That's why I sold mine in the end. Korg's dedicated FM synth isn't very good at FM. I did like the comb filter though.

Some new sounds with extreme modulation for Korg Opsix:

We need an update for the opsix with

1. Multi stage envelopes

2. Envelope rate scaling

3. Ability to patch things to the ratio encoders which are kinda redundant

4. The other 2 FX to fill the blank spaces

5. More than 16 steps in the sequencer

6. A downloadable metal chassis to replace the cheapo plastic

LOL - indeed, and with quality jacks

plus a Midi Thru port and Kensington lock.

The Korg Opsix can do physical modeling synthesis !

Way back when I got mine through the blowout sale, I had an issue where a cord could no longer be put into one of the outputs -- the one which is also the the mono output. Upon learning that nobody else in the history of Korg synthesizers had ever had this issue, I declined to return it, and instead opened up the opsix to find that the plug's spring/contact was the culprit -- fixed by gently bending it up a little with a small screwdriver.

Then of course, the screen failed before I could use it again, and so: off it went for warranty repair. Thus passed the first few months I had it.

After sitting in its box the past year, I hazarded putting it into use again ... and after a couple plugging/unpluggings, once again the output jack refused to accept a cable. Same issue, so I opened the unit again, to bend the contact/spring again: a process which involves the removal of 16 screws of three different types (8 phillips on bottom, and 8 allen screws on top -- of two different sizes), requiring the better part of an hour (partly because i didn't remember which screws were necessary to open it).

What really surprises me is that (according to Korg, and other posters here) nobody else has this issue. Perhaps everyone else has simply hooked the machine without much plugging/unplugging -- which would certainly be ideal, but hasn't been my circumstance.

All I can say is: I'd hate to see this one cheap part metal-fatigue and break, from my bending of one small uncooperative bit of metal. Now I've resolved to place a permanent short cable in that output, and never remove it; I'll use an adapter to a longer cable for actual use. Sure, there's the headphone output -- but I've seen the guts of this thing (twice) and it's no better-made than the one which is failing. Seems fantastically unnecessary, but this one undependable output jack undermines everything this synth can do; if you can't hear it, the rest doesn't matter.
