Ptah Ars (only memeber of This Appear..so far) is a homemade producer starting his own musical production journey in 1999 with Playstation console and a software called Music 2000 (anybody remember that?).
Then it came the first Fruity Loops and soon Reason (daw). Reason stuck with him for almost 10 years and then he discovered Ableton Live.
Today, PtahArs uses Ableton Push for arragmenet and musical progression and his still innovative approach towards musical production.
