I want to know what is the sound (or instrument) which forms the main melody in the drops from these songs:
Disclosure - You & Me (feat. Eliza Doolittle) (Flume remix) (you can hear it starting from 01:04);
The Chainsmokers - Roses (feat. ROZES) (starting from 01:27);
What is that sound / instrument called? If I had a digital keyboard and a way to modify the output, how could I reproduce it (what modifications should I apply)?
