In early 2020, Ernest led CHOPPA, an ambitious music festival that celebrates improvised and electronic music, featuring musicians from Southeast Asia, Australia, US and Europe. In his role as production manager, the event witnessed an upgrade with a 5.1 surround sound system and a larger crowd compared to previous years. He was also involved in 'Potion' as part of MeshMinds 2.0: ArtxTechforGood, an exhibition at ArtScience Museum. This 8-step sequencer, utilising sounds on board the Arduino with an LED array displaying visuals that react with the audio, is housed in a repurposed shoebox. Ernest also mastered Cravism's album vibes, Vol. 2. The album features Maya Diegel and explores the theme of humanoids and artificial intelligence.
