bass333,

Welcome to the forums.

Please tell us a bit more about how you import the MIDI file.

Presumably this is a Drums MIDI file only and doesn't have any other instruments?
In that case, the sound is coming from the output MIDI device that you are using, not the MIDI file itself (MIDI is only the trigger data for the sound module)

When you load a style, you may be over-writing the MIDI file and replacing it with the Drums track from the Style you are using. Can you advise which Style?

Which track did you load your MIDI drums onto?

What is the color of that track in the mixer, after you load the style?

A VSTi may improve the sound, but this depends on the quality of the current MIDI output device.
