The CP80 and the Rhodes are great tools to layer more dynamics.
The CP80 has a great sound, but it’s narrow. It is usually played through a compressor to give it that sustain. This ensures the decay holds out, and adds some grit.
Reverb and delay are commonly used for the CP80. The delay will add another percussive element to it.
Luke tends to layer another sound with a CP80, or use it to play a melodic sound. He doesn’t use it for chords. It’s an accent to something that’s already being played.
The Rhodes piano is very common in R&B music, and it has a very soulful sound. It’s very electronic, and has almost a bell-type sound to it. The Rhodes is monophonic, like the CP80, and needs reverb to create width.
Luke demonstrates a Scream 4 drive through Reason.
Without reverb and delay you can achieve a percussive sound with the Rhodes using the drive.
Your job is not only to play the right notes, but to also play with the right tone. Luke prefers more sparse playing in a worship setting. You might just accent or echo the melody in the chorus.
