Application roots come from demoscene
In late 80s code hackers had a desperate need in fast music composing environment.
First musical tracker appeared on Amiga platform .
It was Ultimate Soundtracker by Karsten Obarski.
ULTIMATE SOUNTRACKER 
A bit later all tracker buzz was transfered to PC platform.
is a product of Finnish demoscene group Future Crew
It was written in C and Asm. Successful text-based GUI, which was borrowed into more advanced Impuse Tracker later.
SCREAM TRACKER 
The most powerful DOS tracker was Impulse Tracker
Software was written in pure assembler, supported plethora of abbilities like:
- insanely rapid due to asm nature [can output hi-quality music even on 486 CPUs]
- direct control of 64 channels

- and much more
IMPUSE TRACKER [1995-1999]
Development of Renoise tracker was started in 2000 by Eduard Muller [Taktik] and Zvonko Tesic [Phazze].
It was based around another tracker called NoiseTrekker made by Juan Antonio Arguelles [Arguru].
Full Renoise history can be obtained here .
Wrapping things up i can definitely confirm that software worth every penny.
Note that I extremely rarely say such things.
Another fine example is Affinity Photo .
Excellent quickstart tutorials to speed up your learning curve.
