I created a Combi as follows: 1) Ferante Piano, 2) Ferante Piano, 3) Ferante Piano (transposed down 1 octave and key range from C2-C3 and key velocity > 100, 4) Japanese Grand, Velocity >110.

This gives me a thick sound, I can get a octave note for the bass keys where I run out of keyboard on my KronosX 61, and when I need it loud and bright, the Japanese Grand Kicks in.

While playing it today, after hitting several strong fully voiced cords, the Japanese Grand sound disappeared. Examining the Combi 1 found the volume on the Japanese Grand at 0. It had been at 127. I raised it to 127, began striking the chords again, now watching the screen and after several strikes I watched the volume for Timbre 4, the JG volume, moved to 0 in front of my eyes. I checked the performance meter and I never saw the polyphony go very high.

I played around with it. I returned Timebre 4 volume to 127 and saved it again. After playing around a while it seemed to hold. But I'm anxious to find out why one of my timbre's in a Combi would move to 0 on its own.

Typical issues to check are:

- KARMA
- unintended movements of sliders/joysticks etc.
- connected midi-equipment.

If it's nothing out of the above, this issue sounds very strange - but I'm quite sure there is a VERY simple solution once you know what's causing this.

I was hoping for a bit more help. The vector joystick was centered. I was watching the screen where you can select the Timbres and then adjust their relative values with the sliders under each timber. I had no other Midi devices connected.

All 4 timbres were at 127. I started striking fully voiced chords, an F# holding 4 notes of the chord in my right hand, and octave F#s in my left. After the third or 4th strong strike, the slider on Timbre #4 jumped to 0.

It happened 3x while watched it, each time sliding the volume slider back up to 127.

Any other ideas anyone? I don't want this to happen in the middle of a gig.

Again, the timbre that jumped to 0 was one where I had the velocity set to 100 or 105.

there's probably a simple explanation for it, but without the combi it's hard to determine what's causing it.

Thank you for the reply and food for thought. Let me provide additional information and ask a couple more probing questions.

- KARMA: As a new person to Kronos I haven't experimented in learning KARMA at all. So I was not using Karma.

- No Midi Equipment attached.

- The original incident occurred while I was on the Set List page. I was intending to practice the song so I was just playing off the Set List when suddenly the higher pitched Japanese Grand sound disappeared. I went to the Combi to investigate why and noticed the slider for Timbre 4 at 0. I reset it to 127 without saving. Started playing again while on that page and saw it jump to 0 again. I repeated this several times. Then I played around, re-saved the Combi at 127 across the board and somehow it seemed to stay.

- Vector Joystick: This I have to honestly rethink. I know that this joystick affects sound radically (another feature I haven't fully investigated yet) and in my opinion it is a bit loose and does move from time time to time without me touching it. To prevent this when playing live, I usually remove all vector joystick functions if I can find out how, but I've not successfully figured that out on all synth engines.

Is it possible that the joystick was in a position that caused the Timbre value to jump to its physical position and override what the Combi called for?

- It was the same Timbre that jumped each time, Japanese Grand in slot 4. To correct it, I would tap on the slider to select it and use the slider to the left of the screen to reset it to 127.

- I do not yet know about using AMS sources to affect the sound. I simply assigned a Timbre to each of the first 4 slots, adjusted the key ranges and the velocity on #4.

- I will play while viewing the page you described and see what I observe.

- How do I post a Combi on here for others to evaluate?

Thanks again for the suggestions everyone. I love this keyboard and am grateful for this forum.

I'm sure this is a relative simple fix. I am not assuming I have a defective keyboard. I just need to understand what I may have inadvertently done to cause the issue. Thanks again.
