Mixing from 7A to 1A

How to mix this transition

Bring in the new track at a phrase boundary in the outgoing key, not mid-phrase, so the jump reads as intentional rather than sloppy. Use a short blend window (4–8 bars maximum) to maximize the shock; a slow crossfade dulls the impact. EQ-kill the mids and highs of the incoming track for 2–4 bars before the swap, then restore them hard on the downbeat to punch the new key into focus. The kick and bass must lock immediately—any lag in the new track's low end will make the transition feel unresolved. Avoid layering both tracks' basslines; choose one and commit.
