Quite frequently. I would say daily or more, I have a problem where MIDI controller data is spewing out of my Nord Lead 2. This is happening even though I'm not moving any knobs. I can see what CC# it is by going into step edit on my sequencer and seeing what they are.
Then I consult my Nord Lead 2 manual and determine which knobs need to be moved around until the data stops. Sometimes it can take a few turns to get the data to stop.
It seems to be mainly certain knobs eg amp env attack, amp env sustain, Osc tune, Fine tune etc.
Is there a fix for this?

I don't know the age of your synth, so maybe it can be the pots which are getting warmer and change their value a little. In the Yahoo mailing list I answered you to us the [Shift+LFO1-wave form] combination, which shows the values in the screen. If it jumps a little between two values it confirms this.

Hello Wout, thanks for being helpful. I need you to make your instructions a little clearer. I tried holding down the shift button and then pressing the LFO waveorm button and then the Osc 1 waveform button all at the same time. The screen said... Ooops, I got it! it is showing the value of the pot I touch/turn. Yes it conforms the problem by showing unstable values when I release the knob. I think it flickers between a few close values instead of sitting on the value I leave it on. It seems to mostly be certain pots. Amp env attack, sustain, osc tuning, osc fine tuning. Could this be fixed?
Roman.
Yes. Mostly Clavia will replace the complete panel board.

In need of spare parts or maintenance?
Warranty and maintenance is handeled by our distributors, and in some cases by special service centers. Please consult you point of purchase for detailed information.
Otherwise contact Clavia using 'support' on their site http://www.clavia.se
Soldering on a print board nobody likes, so...
If you can find the board, you can even do it yourself.
The NordLead isn't out of production, so there is a fair chance to get it replaced.

In my synth Amp Sustain does it a lot...
It's caused by heating by the power supply.

Now how to solve it...

Are you sure it's caused by overheating. My repair man reckons it could be caused by dirty pots.

In my synth it happens only to the Amp Sustain, which is just above the coil! But I'm not a repairman Smile
