Sub Authority MIDI – Trap & 808 Basslines

Sub Authority is a MIDI bass pack built for modern trap and 808-driven production.

These basslines are tight, heavy, and intentional. Patterns are written to hit hard on downbeats, leave space, and use slides only when they serve the groove.

All 115 basslines are 8 bars long and written in minor keys only. Notes stay in a sub-safe range, with controlled slides and grid-locked timing to keep the low end focused. Everything is placed with purpose.

Tempos range from 65 to 80 BPM in halftime feel, translating cleanly to 130–160 BPM in double time. They work with any 808 or sub bass plugin.

This pack is for producers who want 808 MIDI that already knows where to hit.
