How I Did It
Uses samples from:
Tools I Used
Mac Pro
Propellerhead Reason & Record, Cubase 5
Samples I Used
lisadb's Easy Killer vocal and piano sample.
Peff's Vintage RDK refill.
Reason's Subtractor synth.
Process
I sliced the piano sample in Cubase. Some parts were re-arranged and bounced down and just played from audio tracks within the daw. Other parts were loaded into Redrum to be triggered by midi notes.
The slicing are not really well done. As you can hear I should have been more careful with xfading.
