Mixing from 1A to 3A

How to mix this transition

Bring in the incoming track at a clear phrase boundary — ideally at the start of an 8- or 16-bar phrase in the outgoing track. Use a short blend window (4–8 bars) to let the new key settle; a longer blend risks muddying the lift. EQ-wise, avoid heavy filtering on the incoming track's low end during the transition — the energy gain comes from the harmonic shift itself, not from a filtered build. Common pitfall: layering the kick swap with the key change can feel chaotic; instead, lock the kick first, then bring in the melodic elements of the new track once the rhythm is solid.
