I have a problem with my lp, about osc2 frequency. I make my sounds at home, and usually after 1 hour or more of warm up, i save the preset in Lp memory. When, in another day, i turn on little phatty and select that preset, is all ok, detuning is exactly that i choosed the first time when i saved it. But when i go to play with my band in our box (wich is more cold and wet), after 1 hour or more of warm up that preset is much more detuned, so i have to adjust manually the frequency of osc2. If i save that preset in the box, when i will use it in my home, it is again too much detuned. Isn’t this normal or really the osc2 freq depend on ambient?
I ve tried an oscillator 2 frequency calibration. In the manual is written that when calibration begin, the display will appear as this: ‘60 28552 64.37’ where 60 is the base note for calibration (midi note 60), the second number is the calibration value and the third number is the actual measured note, wich is displayed in midi note number cents.
I don’t know the reason, but when i start my calibration, the base note is not 60 but 72, and doesen’t go to 67.00 or 53.00 while calibrating as described in the manual…anyway after a while is displayed the message “SUCCESSFUL”. What do you think about?
yes i’m using autotune function, it works well. What is strange is the difference in detuning amount when i use lp in cold places. I don’t know, maybe the warm up takes more the 1 hour? I m very interested to use little phatty on stage, and on stage usually i can’t wait so much time until the warm up is finisched…and it will be a problem if each preset that i ve programmed in my home will sound different on stage because of different temperature. What’s your consideration about using lp on stage?
I would email Moog support. Mine takes about 20 minutes to warm up (and stay in tune) in most environments where the temp is already 65-75. If it is significantly colder then anything is possible but I’m not sure.
the solution might even be to turn the auto tune off! This sounds like such a case in which it might be the problem. The auto-tune doesn’t take care of OSC 2, only OSC 1! It’s easier to adjust the LP tune during playing when needed, but if properly warmed up it shouldn’t need it during play.
So the fine tune knob takes care both of osc1 and osc2? i didn’t find this, i will try!
I would ask: when you make an osc2 freq calibration, the base note for tuning is 60 as described in user manual? because when i start that calibration i have midi note 72 as base note (maybe 1 octave up?) and i don’t understand if this is normal or there is something wrong
I’ve thought about this a lot. If I were really worried I would only use 1 osc patches and auto-tune. Mostly though I save each patch with the OSC 2 tune active, so when I call the patch up I can easily just tweak the tuning of OSC 2.
I have also saved some patches 3 times: a “cold” “normal” and “hot” patch, and each patch has OSC 2 tuned different to take account of whether it’s a hot or cold day. That works well too.
The SP is small enough that maybe you can just plug in the power back-stage when you arrive to start warming it up? Then when you start setting up on stage make sure it’s the first thing you plug in. By the time everything else is ready it should be good to go.
People who aren’t affected by this are most likely in a nice stable temperature controlled studio, there are no problems if you always have the same room temperature and the slim is warmed within 15 minutes. However my studio isn’t that well controlled. The temperature can vary between about 8c and 30c. There is a lot of tuning difference then!
I just see this as a price I’m willing to pay for the very genuine sound of the phatty.
thank you very much for your precious suggestions! i really appreciated! yeah i also was thinking to leave osc2 freq led active to can adjust manually if the detuning is too much for playing. Nice idea to duoble the preset with different osc2 freq, i will try it
Yes in the studio there is no problem, with a stable temperature lp works fine after 20-30 minuts of warm up. I don’t want to renounce at phatty sound because i really like it, so i am investing about using it outside of studio, where the temperature could be much more unstable.
I don’t have a sufficient knowledge about analog to know if there is something wrong in my lp or if this detuning fluctuations are normal. I ve contact moog support and they suggest me to make a factory restore and a new calibration. Tomorrow i ll play outside of studio so i could see the situation^^
