Mixing from 9B to 11B

How to mix this transition

Start your blend at a clear 4- or 8-bar phrase boundary in the outgoing track; the harmonic distance demands a clean handoff rather than a long, layered crossfade. Use a high-pass filter sweep or EQ kill on the incoming track's low end during the first 4 bars to let the outgoing kick and bass dominate, then bring the new track's bottom end in fully as the second phrase locks. Watch the kick swap carefully — a sloppy kick overlap will muddy the lift. A 1–2 BPM increase (e.g., 120 → 122 BPM) sold with a snare or hi-hat roll into the new key will make the energy jump feel intentional rather than abrupt.
