Piano roll is a program that was included in the MIDI sequencers in the early nineties. It allowed musicians to create in a graphic manner using a keyboard and not needing to use a score. This system managed to eliminate trackers and enhance the production environment through computer programs.
PianoRollComposer allows you to compose compositions using up to 128 instruments, 61 drum tracks and more. This is enough to create an electronic musical theme that is comparable to classical music.
The interface is simple and allows you to see the tracks and all the instruments, as well as the rhythm programming. You can also differentiate using colors.
This application lets us export MIDI files to another program. We can also WAV to allow you to play them with any audio device. PianoRollComposer is a powerful and completely free production system that uses Piano Roll for creating the lines of instruments.
