Little Phatty Oscillators Track Problem

Hi,

I’ve recently had my Little Phatty serviced and now when I choose the Track behavior for the knob behavior the Oscillators section is doing some strange things.

Basically if I select something to change, like the OSC 1 level, I set the knob/dial to a value but when I choose something else to adjust, like the OSC 2 Freq, the OSC 2 value starts to slowly move until it matches the physical position of the knob. If i then cycle through the various buttons in the OSC section then all do the same thing once selected. If I change the knob behavior to Pass-Thru it all works as expected. The current firmware/operating system is 1.03Sc

Does anyone know if this is an option I can turn off or does it need to go back to be looked at by the guy who serviced it? I’ve read the manual and tried looking it up on the internet but no luck so far.

Thanks for any help

It looks like the “crazy LED” problem: it’s caused by bad quality voltage, IIRC. I observed it just last week for the first time.
If this is occuring at your usual location, contact the service guy to ask him whether he touched anything related to powersupply.

Other forum members may give you more useful info though.

Hi,

Thanks for the reply (sorry I’ve not responded earlier; I’ve been away). I’ll get in contact with the guy who serviced it and find out if he did anything with the power supply. If I find anything out I’ll post it on here just in case anyone else comes across the problem.

Thanks again
