ProTrekkr is a tracker program combining a software synthesizer together with a traditional samples tracker which can be used to create electronic music. This program is based on the program NoiseTrekker written by Juan Antonio Arguelles Rius. The program can be used to make music for small sized intros, demos or games. The Amiga OS4 version is made by Fredrik Wikstrom. ProTrekkr is also available for Linux, Mac OSX and Windows.
