Sounds like a solid plan. First isolate the old synth line with a spectral slicer or a simple EQ to pull it out clean. Then chop it into 1‑2 second slices so you can re‑order them or stretch them without losing the groove. Use a granular synth to layer those slices with some of the new futuristic pads—just keep the grain size small so the texture stays tight. For the AI beats, feed a MIDI pattern into a neural‑drum generator, then run the output through a side‑chain compressor so the bassline can breathe. Finally, run the whole mix through a de‑esser on the high mids and a gentle reverb to give it depth. Keep tweaking the attack on the synths, and you’ll have a clean, dissected remix ready for the lab.
