It was even worse!
Considering the quality of your samples and the fact that you supplied a GUS sample for PD lets me assume that you're playing one of the more advanced re-releases of Pinball Dreams, which actually has a quite decent MOD player.
The MOD player in the original 1993 version of PD sounds much worse. The game was supposed to run on 286/386sx machines, but this kind of CPU just barely manages to mix a 4-channel MOD at 22 kHz while doing nothing else! In order to keep the game playable at decent frame rates, the developers had to reduce the sample rate even further.
yeah, I have that version too....the one with Roland LA synth support.
The scrolling is terrible on it too

Here's an example how the Gus Classic handled the Pinball Dreams title track
