Rosegarden – Music editor and MIDI/audio sequencer
Rosegarden is designed to look and act in a manner familiar to experienced users coming from the commercial software world, while also being accessible and friendly to users new to music software generally.
Rosegarden provides three distinct ways of viewing, editing, and entering MIDI events, including a powerful notation editor that provides many advanced features not typically found in the notation facility of MIDI sequencers. Underneath these three editors, Rosegarden provides a segment-based mechanism for arranging blocks of MIDI and audio data on a canvas that brings something akin to the flexibility of a layer-based image editing program to the realm of music.
Rosegarden is built using Qt – A cross-platform application and UI framework. It uses ALSA to provide MIDI support, and JACK for audio, both of which limit Rosegarden to Linux for the time being, but that should hopefully change in the future, with OS-X being the next most accessible platform, and Windows the most difficult to reach.
Install Rosegarden in ubuntu
Open the terminal and run the following command
sudo apt-get install rosegarden rosegarden-data
I actually use Rosegarden exclusively to control my three hardware synths. I love it because it works reliably and includes control files for each synth that I own, so I can control almost every aspect of my hardware synths through Rosegarden and never have to touch the hardware hardly at all. Also, it’s linux, so super-stable. Works with jackd, so with the real-time kernel module, there’s no perceptible delay from key press to audio.
