MusicDJ is an old application included on old Sony Ericsson phones which let you made tracks based on pre-defined sounds. The tracks were saved on a .midi format, meaning what you could finish editing them on a PC before converting them to MP3. Unfortunately, when Sony Ericsson was converted into Sony Mobile Communications, this application was forgotten.
HG managed to get all the sounds from the application, to start re-creating this application for PC. With our knowledge about websites, we will write an online application as it was on the old Sony Ericsson website. There was a standalone version in the works, but unfortunately, Njifra decided to leave the team. This means there won't be any plans for a standalone version right now.
