Osc 2 Freq setting and factory presets
Osc 2 Freq setting and factory presets
Many of the factory patches on my LP seem to have excessive detuning on osc 2. Is this just a normal manufacturing variable or has the calibration been perturbed in shipping? I don't see a global variable to adjust this, so if normal, I assume that I need to tweak Osc 2 Freq on a patch by patch basis.

You read correctly.
The manual does recommend letting the LP warm up. I can't remember the time recommended.....I think it was 15 to 20 minutes. Mine is pretty good almost immediately after turning on.
I have one preset patch where oscillator 2 is way detuned. For whatever reason (lazy I guess) I have not corrected the pitch and saved the new setting. I think that it might have been done incorrectly or when the machine was not warmed up and the oscillator stable. Other than that, my patches all sound pretty good and in tune.

Thanks for encouraging me - I found the reference! It's in the addendum (which has the same date as my birthday by the way). It states:
"- Warm up period for oscillators
It is recommended that a warm up period of about 15 minutes be allowed before using the LP. The LP's VCOs use a heated chip design that takes a short time to warm up. This period may be longer if the LP has been stored in a temperature outside the recommended operating temperature range."
I loved reading about the early days of Kraftwerk (not in the addendum, of course, but in some biography) where they would go out and tune the synths before the show started, but need to retune once the show had begun because the temperature in the room would have changed. Until then I had no idea that you had to tune synthesizers!
EDIT: I found a reference, though not the one I was thinking of. It's from Wolfgang Flur's I Was A Robot, p. 62:
"We managed to achieve a respectable length for the show, but even the protracted tuning and recalibration of the synthesizers between the songs was so interesting to the audience that our mini repertoire wasn't a problem."
