Little Phatty Stage II CV Mod Tracking Problem
Little Phatty Stage II CV Mod Tracking Problem
I just received my new Little Phatty Stage II with the CV Output Mod. I am having problems using it to control a Synthesizers.com Oscillator. It seems like the Little Phatty is not actually sending 1volt/octave from the Pitch CV Out. A scale starting at E tracks to 25cents short of Eb one octave up. I hooked up my handy Multimeter and it confirms my suspicion, the Little Phatty is not sending 1 volt per octave. Is there a way to calibrate the Pitch CV Out to work at 1 volt per octave?
I am pretty frustrated at this point.
Thanks

I wonder if it's because the LP functions at .95 or .97 volts/octave internally. Just a tad less than 1. When the CV out mod was proposed on this forum I ask if the CV out mod would send a full 1V/octave and was told yes. This was by a member of the forum quoting info he was given by Amos.

I sure hope it's not an issue with all CV out mods. I was hoping to get the CV out mod myself and would need to reconsider if it does not play well with others. If you have a CP-251, you should be able to play with the signal till it tracks properly. Just a lot of fiddling.

I wish that could be used for the CV ins as well, as I was never able to use the LP with other 1v/oct devices due to the .96 or .97 system it uses...sucks, as I did try with the CP but it was a pain in the arse. too sensitive and the notes just always sounded funny as it tracked up or down.

Did anybody else experience problems with the CV out? My Stage II with factory installed CV out is way off...

CV out should be 1v/oct.
CV in is .97v/oct or there abouts

My problem is more that, for instance, C3 is more like "F3" compaired to other equipment.... Can that be adjusted somehow? I've tried all the calibration rutines...

Hmm… F-based keyboard on the controlled equipment, isn't it?

F-based? Is that a thing?
My other CV-capable equipment (Elektron Analog Four, Anushri, ES-1) is waaaaay better calibrated, so the Little Phatty's... erhm "deviant" behavior surprises me....

Re: Little Phatty Stage II CV Mod Tracking Problem
I saw this between some "regular" CV'd equipment and a MG-1, which is precisely F-based. As I understood your scale is right but offset by -say- a fourth (C to F), I had this idea.
Now if you think something is wrong, you definitely should write/phone to Moog techs.

When I sent my 3 Phattys (1x Little St. II, 2x Slim) to my local Moog tech (for another problem), I also got him to calibrate all of the Pitch CV In's to 1v/octave.///OSS wrote:I wish that could be used for the CV ins as well, as I was never able to use the LP with other 1v/oct devices due to the .96 or .97 system it uses...sucks, as I did try with the CP but it was a pain in the arse. too sensitive and the notes just always sounded funny as it tracked up or down.
It can be done..
