Hey there @QbO
Honestly I think it's gonna be quite difficult to find that kind of specific content online, most of the sound pack creators & resellers are offering full packs with samples & loops and Midi is something extra in general. It's true that there's also exclusive Midi packs but then it's more dealing with melodies & chords progression than drums.
I know that Sonic Academy has got a specific Trance Pack in their Ultimate Drums bundle ( you can get each pack separately and it contains some Midi patterns as well as Ultrabeat & Ableton Live DrumRack kits.
You'll find the bundle here and if you scroll through the page you'll be able to purchase the Trance Pack only.
S.A will soon be launching their Black Friday sale, so it could be on sale as well in a few day, stay tune with their social medias and make sure you're receiving their emails from your account Email Preferences
