Dino is a GNU/Linux MIDI sequencer software that allows users to create and edit MIDI files.
Dino comes with a user-friendly GUI divided into three tabs. The first tab is the "Arrangement" tab, where you can add new tracks, edit the tempo map, and arrange patterns. When you first launch Dino, you will only see the BPM track; however, you can add tempo changes by clicking the left button, remove them with the right button (except the first one), and change the BPM by middle-clicking and dragging up and down.
Clicking on the '+' button adds a new track where you can choose a name for it, the MIDI port it should connect to, and the MIDI channel it should send events to. You can also modify all these properties later by clicking the 'Properties' button. Each track is shown as a block strip, where a block represents a beat. When you have created patterns for a track, you can click on the track and bring up a menu listing all the patterns for that track. The selected pattern will be added to the track at the beat clicked, while its length can be modified with the middle mouse button.
The pattern editor is where you can add, edit, and remove patterns for the different tracks. Adding and removing patterns is a simple task, as tooltips make it quite straightforward. You can also add and delete controllers like pitchbend and MIDI CC controllers while you edit the active pattern in the note editor. You can add new notes with the Ctrl-left button, change their length with the middle button, change their velocity with Ctrl-middle button, and delete them with Ctrl-right button. With the left mouse button, you can select or drag notes around as required. Clipboard commands like cut, copy, paste and delete are also included in Dino.
The third tab, the "Info editor," has entry fields for the song's title, author, and info. This tab is quite easy to use, and users should be able to use it without any difficulty.
Dino requires libjack and libglademm to function smoothly. The recent update of Dino adds the namespace prefix Pango:: in a couple of places to avoid ambiguity that stopped compilation, thus making the software more stable and bug-free.
Overall, Dino is an excellent choice for anyone looking for a powerful yet easy-to-use MIDI sequencer for GNU/Linux.
