Hi,
Unfortunately the DM48 preset in SWAM doesn't work well - it is on the to-do list to try to get it updated. So default means what you have right after installing the app without loading any presets in SWAM.
Good settings are close to the "Wind" preset - the major change being that you need to activate velocity sensing on the DM48, or the sound will lack expressivity in the attack. Start with Wind, and set Velocity sens to 10. That's it.
If you are using the pressure-activated bending feature on the DM48, ensure to reduce the sensitivity down to 2 or so (or change in SWAM).
Good luck.
