The Mogees software comes with different sound engines, each with its own set of presets and parameters that you can use to further tweak the sound.
The app comes pre-loaded with 2 different sound engines:
MUON physical modelling re-synthesiser
Interpol808 - A classic drum machine sound emulator.
Blue Steel - A Steel String Resonator
Foxtrot - A retro electro drum synth.
More sound engines will be released with updates in the near future.
