I'm having the same "ghost note" problem on my Korean JTV-59 with FW 2.0.
The altered tunings worked correctly when I got the guitar with FW 1.8. They still worked correctly after I applied the FW 2.0 update.
Then I edited one of the tunings, per the procedure in the manual, and saved it to the guitar.
Now, all of the tunings (including factory ones that I didn't change) pass both the altered pitch and the natural string pitch. Essentially, changing one tuning broke all of them. This occurs on all guitar models.
Here's an example of what happens:
- I select a tuning that lowers the 1st (high E) string to D (e.g., BLUES G).
- When I pluck the string, I hear both D (the altered pitch) and E (the actual string pitch) in the headphones or amplifier.
- If I go into Workbench HD and lower the volume of the 1st string in the tuning window, both notes decrease in volume.
- It's hard to tell for sure, but it sounds like both notes are being processed by the guitar model.
The 1st string in the procedure above is just an example.
- The problem happens on any string that is altered by a tuning, on any guitar model.
- It occurs regardless of whether the guitar is connected to the computer.
- POD presets are not a factor. I do not own a POD with a Variax port. I'm using the USB to MIDI adapter that came with the guitar.
- The mag pickups are not mixed in.
- I am not hearing the strings vibrating on the guitar.
The altered tunings are no longer suppressing the actual string pitch.
I hope they find a fix for this soon. The tuning function is one of the main reasons that I bought the Variax.
