Internet DJ Console is a program that I started writing in March of 2005 after discovering the lack of DJ software on Linux that suited me. The programs that I did find were either feature poor, full of bugs, suited more towards the live side of things, or sadly did not even compile. It dawned on me that something needed to be done and that having some coding skills of my own that I may as well have a go myself. The basics of the different components of the project and how they would fit together came to me almost with ease so after pondering the sketch I drew a few days later I started coding. The result is Internet DJ Console. I hope you like it, and if you want to make any suggestions for features or have a gripe or bug report, you can contact me at putidjcinthesubjectline@bethere.co.uk.
