Vortex Sound Research

I recently bought a Monologue to start learning the ways of the synth, but a lot of times when I turn it on it gets stuck in the loading screen for a long while. I also noticed that sometimes the presets had a weird detuning and the loops sounded out of tune.

I changed the batteries and tried a 9v adapter, but both issues persist. Anyone has had this kind of issue? Any solutions?
