Slim Phatty jumps to one of the factory presets

[TRiCK83]

I´m really happy with the Slim Phatty i bought used, but sometimes when i use it it jumps from the calibration preset to one of the factory presets. Is it maybe a bug in the firmware? What should i do?

Perhaps it depends on the DAW or controller you are using with the SP. When I use it with my Akai MPC 2500, there is a command to wich preset the synth should jump. I have to disable this setting. Hope this helps.
