Yesterday (they first day for me with a Moog) I programmed my first patch which I saved. I had the LP turned off overnight.
When I turned it back on this morning and played the patch, the second oszillator frequenzy was definitely not where I let it.
I have no experience with analog equipment so far, so I wonder if this is something to worry about? I don’t think it needs some warming up time…?
What are your thoughts on this?
Anyway, gotta go back to playing around. Just too much fun 
See if you can duplicate the problem with just turning the unit off then on again. Is the displayed value for the 2nd osc. freq the same? or is it just the audible sound that’s off?

Good idea. I had not even come as far as to discover the precision mode where the values are diplayed in numbers… I will write down some values of my patch and see if they are different at the next reboot…
Is it possible that you adjusted the 2nd oscillator AFTER you saved the patch? Short of a real hardware failure, this is the most likely explanation.
I wrote down the values of the knobs this time and turned the unit off. After a while (it may have been half an hour) I turned it back on. Again the patch sounded not the way I remembered it, an audibly faster cycling between osc1 and osc2 as i would describe it. And the numeric value on the osc2 wave was different!
However, setting the osc2 wave back to the previous value did not restore the sound as it was supposed to be. I had to adjust osc2 freq (playing by ear) slightly to get it right.
I might repeat this a couple more times, turning it off, turning it back on, seeing which values did change despite saving and which have to be adjusted…
Are you sure you are saving the changed value?
The preset button will be changed from pink to blue after you save the preset.
Is the preset button blue after you power it back up?
If the preset button is pink after you power it up, then one of the pots has changed a value.

Yes, it gets saved properly, just as you described. The little weirdness persists whenever I turn the LP off and back on. The stored patch will have slightly shifted osc2 values…
This is probably due to the version of the firmware you are running on your LP… there will be an updated version released shortly which will most likely correct this behaviour. Stay tuned!
Maybe you have a noisy pot.
Does the unit jump from preset mode to panel mode without touching the controls?
What firmware version are you running?

OK! Thank you. Will it be downloadable in the service area?
btw. four of the 6 LEDs in the modulation section, “LFO Rate”. Are flickering slightly and pulsing - in a different manner at about each chosen preset. It looks like they are following some kind of waveform… Is this supposed to be? I left the LP on overnight, but it still does it.
I also had hanging notes (repeatedly) yesterday when I connected MIDI to where it would send MIDI to my DAW. The hanging note was weird, because I could not get rid of it. Even switching to a different preset and back - the tone came back and hitting the same note would not silence it. It was if a sustain pedal was held (but I have none connected)
hm, I will watch out for it…
I have firmware 1.02b
I also can say now that the change in the osc2 freq does not only happen after the LP has been turned off. It also happens - but only sometimes - when I switch to another preset and then back again. It seems the longer I am not using this particular preset, the more the chance that it will be off next time I return to it.
Ok, so I got the firmaware update and I had no trouble installing it via Sysex.
However, the problem seems to get worse.
Now, I could confirm that while playing the preset 24 the display jumped from preset mode into “panel active” without me changing any value on any parameter - just playing a few notes on the keyboard.
There was the MIDI message “*** ZERO *** To Plug 1 Control 1 Controller 3 67” which I am not clear about what it is. There should have not been any MIDI messages besides note on and off while I was playing some keys.
I also encountered more frequent hanging notes. Even after following the advice to set the LP to “Local off”. After about 2 minutes of playing (not only speedy Wakemanesques) I am getting a hanging note for sure - is it possible that other equipment has an influence to that?
Baba: Can you explain your term of a “noisy oscillator”. I am not very educated in the technical arena…
Finally, the mystery about the flickering LEDs was solved. I is actially a nice indicator of what kind of waves are active. Duh, I could have figuered that out, too…
I don’t believe any of the led’s should flicker. Considering the number of things that are happening to your unit, you may have to send it back.
the lfo led should flicker
Unfortunately, I have the same problem now.
After switching to another preset, the sound changes to the current value of the 4 pots and he LP goes imediately in “Panel Active” mode. This renders the LP practically unusable.
My LP functioned normally until today and then started this behavior from one moment to another 
Any idea, what is going wrong here?

Pheewwww… solved.
My mixer sent out a voltage of 1,2 V on the cable that was connected to the LP’s output, for whatever reason.
After checking all connections, re-seating the jacks etc. the voltage was gone and the LP functioned as normal again! 
I experienced the dancing led issue this weekend and was just about to call Moog when I saw your post. Sure enough, it only happened when I had a cable plugged into the output jack. In my case, it happens when the cable is connect to my guitar amp even when the amp is not on. Could it be a bad cable or some electrical issue?
The LP seems to react with unpredictable behavior when signals or dc currents are present on the output cable. Maybe there are more influences such as bad cables, but I’m not sure.
In my case, I took a voltmeter and found a voltage coming from the mixer. After re-seating all the jacks, the problem was gone.
So, the only advice I can give you, is to try differnet cables, re-check connections, etc.
Good Luck,
