Little Phatty pitch bend not calibrating

[Frameboy]

Hey guys,

Just bought a LP SII for a low price with a bad pitch bend. The previous owner wasn't a tech head and had just said it was broken and jumping intermittently. I assumed it was a bad pot and with the money I saved could even buy a whole new pitch/mod unit and still got a good deal if a DIY repair didn't work.

On firing up the LP I found that the pitch bend does not bend down, and when you apply even the lightest pressure up the note jumps up to the highest range and back down on releasing it.

I've gone into the settings and factory reset then tried calibrating the pitch wheel and I'm getting promising signs but then weirdness.

First I get 2054 2058 2061

after calibrations 394 2060 3704 (the final digit of the middle number is always a blur though as it keeps flicking between numbers even when wheel is left untouched. During calibrations the numbers move smoothly suggesting that the pot is working correctly even with the blurring end number constantly in the middle value.

So I hit 'enter' and now I can bend downwards but not up at all. If I go back into 'Calibration' the numbers are back to similar ranges as when I started but slightly out e.g. 2058 2061 2065


Can anyone suggest what to do? The bend clearly does work but saving the calibration isn't working, and the PB wheel wont hold a steady value.

Really appreciate any help!

Hey Andy,

I'm in the UK. I've tried the suggested retailers, but one only deals with vintage (although he was really helpful) and the other hasn't replied to me after a week!

I've just tried emailing your tech support on the main website and will see what happens!

Thanks.

Just an update. It's fixed!

After hunting through the System Utilities menu I found a second pitch bend related setting under PW Amount. I'd realised the unit was out of tune by 2 tones and after letting the PW Amount recalibrate, the pitch wheel started working properly and gave me a bend of 1 tone each side.

The LP also turned out to be out of tune by a fair way from concert pitch. I ran the note recalibration and left the 2 hour long cycle while I went out for a gig and on my return everything was back to factory fresh!

Dead chuffed. Looks like the previous owners had really messed the settings up and figured it was broken without doing any research. Bargain for me

And here we are at the end of 2024!
I was experiencing very similar issues and was able to locate this post, so simply wanted to thank you (frame boy), and others for posting this solution. To add, you may consult owner's manual at pages 45-49 for more calibration options.
These features are great as most analog synths require manual calibration via trim pots on main board(s)!
