Free midi sequencer software for linux

Dino is a MIDI sequencer for GNU/Linux. Dino is a pattern-based sequencer, which means that you write small patterns of MIDI events that you can repeat and arrange to create a whole song.

Each track has its own patterns, so you can for example play the same drum pattern over and over again while you play different lead synth patterns and basslines.

The arrangement editor

The GUI is divided into three tabs. The first tab, "Arrangement" is where you
add new tracks, arrange patterns, and edit the tempo map. When you first
start Dino there will be no tracks and all you will see is the "BPM" track.
Here you can add new tempo changes with the left button, remove them with
the right button (except the first one - if you removed it the BPM for the
whole song would be undefined, so Dino will not let you remove it) and change
their BPM by middle-clicking and dragging up and down. This mousing pattern
is used in most places in Dino - left adds, middle modifies, right removes.

If you click the + button in the arrangement tab you will add a track. When
you add a track you can choose a name for it, which MIDI port it should connect
to, and the MIDI channel it should send events to. You can edit all these
properties later too by clicking the Properties button (the one with the
tool). The selected track (the one that has a dark blue background for its
name) can be removed by clicking the trashcan button.

Each track is shown as a strip of blocks, where each block represents a beat.
When you have created patterns for your track (see the text about the "Patterns"
tab below) you can use the left mouse button to click on a track and bring up
a popup menu listing all patterns for that track. The one you select will be
added to the track at the beat you clicked. You can modify its length with
the middle mouse button and delete it with the right (this does not affect
the actual pattern at all, just how this instance of it is played).

The pattern editor

In the pattern editor you can add, edit, and remove patterns for the different
tracks. Look at the tooltips for the buttons in the upper row and it should
be fairly obvious how to add and delete patterns. When you have added a pattern
you can also add and delete controllers in it. Controllers are e.g. pitchbend
and MIDI CC controllers. The active controller can be edited in the box at the
bottom of this tab.

The main box here is the note editor, where you edit the notes in the active
pattern. You add new notes with Ctrl-left button, change their length with the
middle button, change their velocity with Ctrl-middle button and delete them
with Ctrl-right button. You can also use the left mouse button to select,
unselect, and drag notes around - clicking a note will select it, shift-clicking
will unselect or select it depending on whether it was selected or not, clicking
and dragging notes will move the selected notes around on the grid.

There are also basic clipboard commands, you can cut, copy, paste and delete
the current selection. When you paste you will have to click where you want
the clipboard content to appear. You can also middle-click outside all notes to
insert a copy of the current selection there without affecting the clipboard
content.

The info editor

The third tab simply has entry fields for the songs title, author, and info. It should be obvious how to use them.

MIDI Data Miner uses a neural network to learn correlations between notes and control changes in a MIDI file.

After training MDM can augment a live MIDI stream, adding control changes based on notes received.

Briefly: use MDM by connecting a MIDI device, open preferences and set MIDI input and output ports. Open a MIDI file, create a new neural net and train. Now play notes on your MIDI device, MDM will automatically add control changes.

MDM creates a collection of note and controller pairs from the file and uses them to train a net. The notes are used as inputs and the controls as outputs. The window is the number of previous notes considered when determining the output for the current note. Larger windows give less predictable more interesting responses. Enter a number in the window box and press enter to set the window size.

This is an early alpha release, buggy and incomplete. Please send feedback! Note that this alpha version only reads from the first track in a MIDI file, and only uses the first controller. Look at the included MIDI file in the working/midi folder for details.

midi pong is an implementation of the pong game that works as a MIDI instrument.

Seen it before? As a MIDI instrument? As a VST plugin? When you play pong, you play music. You can try it here as an applet, though thats not half as cute as connecting it to a nice soft-synth sound, adding a few effects (arpeggiator, anyone?) and letting it play some loops for you.

Dont believe me? Try it. If youre too chicken then listen to this sample: pong (1.4mb). Its made up of three voices played by pong - no meddling with the MIDI output, this is pure pong power!

For your incidental compositions you can choose computer, keyboard or mouse control (or gamecontroller if you get the source) for the left and right rackets. You can choose the scale that pong plays notes from when the ball is hit. You can choose the tempo of the performance. The MIDI output device. The MIDI channel. This pong uses Swing and requires Java 1.4 or newer.

Usage:

Download and run with java -jar pong.jar

KMidiTracker is a MIDI Step Sequencer.
A Step Sequencer is a sequencer in witch the MIDI notes are delivered at regular time intervals, usually a 1/4th of a quarter note. As such it is not as versatile as a regular sequencer as [Rosegarden], but allows very easy creation of loops and sequences. The use of the [MIDI Clock] allows several sequencers communicate clock events, so it is possible to join several sequencers, with diverse focus, to make one single synchronized composition.
KMidiTracker is similar to trackers like [FastTracker], [ScreamTracker] or [Buzz], but only the Tracker; no actual sound is emmited. Only MIDI signals.
The Tracker divides songs in tracks, each one have several patterns that are arranged as sequences. Time advance in steps that depend on tempo, and in each time step a new MIDI note may sound, or a controller event may be sent. You can have several columns of notes and/or controllers for each pattern, and pattern length is configurable.
Main features:
- MIDI oriented Step Sequencer
- ALSA MIDI input/output
- MIDI thru
- Keyboard input
- Graphical Controller edition
- Controllers include MIDI Controllers, SysEx Controllers and PitchBend
- MIDI Master Clock (master and slave)
- Linux RTC timer or MMC if avaliable for perfect timing
- Tracks and columns in patterns muteable
- SysEx parameters. Can be loaded from binary file, manually inserted in hex, or captured from midi input.
- Variable Time Signature
- Load/Save
- KDE application: easy menu, toolbar and shortcuts changes
- Everything can be changed in realtime: notes, arrangement, loops, controllers, load/save, new tracks or patterns, delete tracks or patterns...
- [GPL] license

Playmidi is a curses and X11-based MIDI file player for Linux. It supports playback to any OSS-supported synth device including external MIDI.

To install playmidi, just "make install"
make install will automatically configure playmidi based on your answers to a few simple questions.

NOTE: the Makefile is optimized for a recent RedHat setup. If you have an old or poorly installed ncurses, you might have to make some changes to compile. X11R6 is reqired for xplaymidi. If there is an object you dont care to make, or cant make, see the makefile
for additional installation options.

If youre having trouble with playmidi, please feel free to send email. If youve discovered any bugs, feel free to email your bug fixes.

Options for usage:

[x]playmidi [options] file1.mid [file2.mid ...]

There are a lot of command line options to change things like which device to playback to and what channels to play with what patch, etc. There are also compile-in options you will find in "playmidi.h"
