These are polyrhythms, with rhythmic patterns in each of the rhythms of the polyrhythm rather than just a steady beat

Who are these rhythms for?

Help you to play different patterns such as paradiddles, or dance rhythms etc. polyrhythmically.

Then the more exotic rhythms here may be of interest to the more rhythmically adventurous musicians including maybe Math Metal and composers.

You can make rhythms like this with Bounce Metronome Pro using its Drum & Dance metronome - you need to unselect "Syncrhonise beats in all the parts" in it's Dance Rhythms editor (Ctrl + 228)

Triplet pattern rhythms with alternating quarter and eighth notes

These rhythms  have alternating quarter and eighth note beats in all the parts. Sometimes starts with an eighth note and sometimes with a quarter note - depends on the number of eighth notes in the rhythm. So for instance to play a triplet pattern like this in 7/8, you need to go o O o O o (o for eighth note, O for quarter note) stating with an eighth note as that is the only way to get the right number of beats to the measure.

There's nothing special about these triplet pattern rhythms. You can explore any pattern mixing beats of any size in all the parts of the polyrhythm, just as you desire. But to give this page some focus, I thought I'd explore these patterns,  as a way to show the capabilities of the metronome.
