Remember the main window top line pattern sequence goes 0, 4, 8, 12, 16, 20, 24, 28
Using MIDI keyboard, Note on (144), notes C2 (36) to F#4 (67):
See Audio setup

The first number is the pattern/sequence number in the main window, which ranges from 0 to 31. Each set of brackets corresponds to a MIDI filter. The MIDI filter in the left most brackets is the toggle filter. The MIDI filter in the middles brackets is the on filter. The MIDI filter in the right most brackets is the off filter.
If the incoming MIDI event matches the filter, it will either [toggle], [on], or [off] the pattern/sequence, respectively. The layout of each filter inside the brackets is as follows: [OPR INV STAT D1 D2min D2max] where:
- STAT=MIDI status byte(channel ignored)
- D2min=data2 min
- D2max=data2 max
If on/off is set to 1, it will match the incoming MIDI against the MIDI status byte pattern and perform the action (on/off/toggle) if the data falls in the range specified. All values are in decimal.
The inverse field will make the pattern perform the opposite action (off for on,on for off) if the data falls outside the specified range. This is cool because one can map several sequences to a knob or fader.
The MIDI status byte field is a MIDI status byte number in decimals. The channel nybble of this byte is ignored. One can look the possible status values up in the MIDI messages tables. As the channel on which the events are sent is ignored, one should always use the values for channel 1. That is, 0.
The last three fields describe the range of data that will match. The data1 field provides the actual MIDI event message number to detect, in decimal. This item could be a Note On/Off event or a Control/Mode change event, for example.
The data2 min field is the minimum value of the event for the filter to match. For Note On/Off events,this would be the velocity value, for example.
The data2 max field is the maximum value of the event for the filter to match.
- Non Sequencer - a powerful, lightweight, real-time, pattern-based MIDI sequencer for Linux--released under the GNU General Public License (GPL). It utilizes the JACK Audio Connection Kit for MIDI I/O and the NTK GUI toolkit for its user interface.
You put non-sequencer into trigger mode and send it CC 20 messages, where the value part of the message is a pattern number to trigger.
Keyboard bindings are wonky.

- Epichord - a midi sequencer. It allows you to arrange midi patterns to be played on midi aware tools, record midi, and store/load arrangements to/from disk. It does not make sound or handle audio in any way. That is the job of other midi programs and hardware to which it can connect. Epichord is a clone of what seems like countless programs available on windows, as well as some attempts to bring this type of tool to linux. In particular, it emphasizes a plain and 'overused' user interface which I believe existing tools either ignored to pursue something better, or just ignored. Here is a partial list of programs which serve as inspiration for Epichord in various ways.

Grid step sequencer
- CYTHAR-Sequenzer - 96 crazy oscillating strings. A pattern-oriented, polyphonic MIDI step-sequencer, which makes its own path. 16 parallel patterns with six tracks and 16 bars – equating to 256 bars & 96 tracks. The six pattern tracks imitate the strings of a guitar and will be tuned e.g. to “EAdgbe”. With some clicks you can set a guitar chord to the pattern tune – then by enabling a few events or triggers the sequencer will start a solo or plays with the chords. More offset-, mute functions and a tricky song mode will pep-up your set. With CYTHAR you can program drum sets, melodies, arpeggios and complete songs.

- Amuc - Amuc is a Linux application for composing and playing music. The current version is 1.7 (june 2009). It works like this: Tune fragments are entered graphically. These are combined into a complete tune by means of a script file. Five-bar staff or piano roll display. 5 different built-in instruments, 6 mono synthesizers, synthesized drums, sampled instruments. For the composer there is help available with scales and chords. Tunes can be exported as WAVE or MIDI files, or as human-readable scores in postscript format. MIDI files can be imported. WAVE files can be read and transformed to notes. Support for USB keyboard. Interface with Jack (the Jack Audio Connection Kit). Amuc is written in C++. It is a lightweight application, not needing a GUI toolkit or an unusual library (required: X11, alsa, xft, cairo). Speedy operation: maybe this is the fastest tool to explore musical ideas and to create a complete piece of music. 1.7 (june 2009)
Jazz++ MIDI Sequencer
- Jazz++ Midi Sequencer - application for recording and mixing MIDI sequences, and for many years was the only stable application like it that ran under both Windows and Linux. Unfortunately, it has not been well maintained and was starting to look a little long in the tooth. It was also written with the venerable wxWindows version 1.68, which is not only now obsolete, but isn't even called wxWindows anymore. Last release 2008, last commit 2015-04-05
- MidiMountain - a MIDI sequencer aimed to edit standard midi files. The easy to use interface should help even beginners to edit and create midi songs (sequences) with this application. For professionals, MidiMountain is designed to edit every definition known to standard midi files and the midi transfer protocol. From easy piano roll editing to changing binary system exclusive messages, MidiMountain is complete and usable for every midi user.
- Brahms - Brahms is a sequencer and professional music notation program with several editing methods, including Score, Pianoroll, Drum, and Mastertrack Editors. For C++ programmers, it is easy to write new plugins (without recompiling Brahms). MIDI import and export are also implemented. It is compatible with KDE2.x and the aRts software synthesizer.
- STed - high-performance MIDI sequence editor / Music composer system. It had been working on X680x0 old Japanese personal workstation, ported the STed to UNIX & X environment. ncurses or X versions. Last modified: Mon Nov 4 16:56:25 2002
- KeyKit - an awk-like language developed by Tim Thompson and designed specifically for manipulating MIDI data. The full KeyKit system includes a multi-window and multi-tasking graphical user interface, and can be used for both algorithmic and realtime applications. The language itself has only a few built-in functions for graphics - the entire user interface is written in KeyKit itself, and is hence completely customizable and extensible by the user. The current version works best on Windows NT and Windows 95, but the software is designed to be portable. Previous versions have been ported to a wide variety of systems, including UNIX, DOS, Mac, Amiga, and even Plan 9.
- Keynote -A Language and Extensible Graphic Editor for Music - Tim Thompson AT&T Bell Laboratories, 1990
Keynote is a programming language for manipulating and generating music with MIDI-compatible equipment. It was designed for and int he style of the UNIX software system, as an application-specific "little language" and interactive shell. Most obviously used for algorithmic music composition, Keynote also serves as a more general utility for non-realtime and realtime MIDI data manipulation. By adding only a few functions to the language, a graphic interface was recently added. This built-in graphic interface did not, how-ever, build-in any particular user interface. All the nested pop-up menus and operations of a graphical music editor have been implemented in the Key-note language itself. The result is an extensible tool,similar in spirit to the Lisp-based extensibility of emacs, easily modified and enhanced by end users.

- AlgoScore - a graphical environment for algorithmic composition, where music is constructed directly in an interactive graphical score. The result is output as audio (through CSound), arbitrary control data (through JACK ports) for control of other applications, MIDI through JACK or to file, or OpenSoundControl messages. The generated audio can be played back through JACK or exported to an audiofile.
- Duration - a timeline for creative coding. Create live performances, interactive installations, and music visualizations by synchronously composing servos, lighting, and projection. Intended to integrate with creative coding platforms like Processing, Cinder, openFrameworks, and vvvv Duration controls parameteric change over time with an easy to understand keyframe timeline editor. The application sends values over OSC and can be configured through OSC messages. Open source and completely free, Duration may be used in art, research, or commercial projects. It's built with openFrameworks, and inherits its commitment to openness and sharing.
- https://github.com/sukovec/jackmididrummer - Easy configurable drum machine/sequencer. Controlled by MIDI, emiting MIDI. The goal of this small piece of software is to make simple textually configurable drum machine where individual drum loops can be switched using midi. It is pretty basic piece of software... but it works. However, stdout is full of debug output, some features are not implemented yet
- quincer - a MIDI sequencer for composed music, reads text files for input, which may include other input files to re-use material. It is a pure JACK client.
- Mish - MIDI shorthand, a text-based music notation language. A song represented in Mish is similar to a computer program represented in C. It is human readable, but needs to be compiled into a binary form, namely a standard MIDI file, before the computer can play it. Mish can also be written out with pencil and paper, but it is not optimized for a musician to perform from, as he would with CMN.
- https://github.com/cepthomas/Nebulator - C# makes a reasonable scripting language, given that we have the compiler available to us at run time. Actually you can create compositions without any script functions at all, but they are there if you want them. The main music part is all declarative. While the primary intent is to generate music-by-code, runtime interaction is also supported. It's called Nebulator after a MarkS C++ noisemaker called Nebula which allowed manipulation of parameters using custom UI inputs, and display of whatever on the UI. A simple API for UI functions is provided - it's a subset of that provided by Processing. Also, the new functions that support music are modelled after that API style.

- GMS (Gestural Music Sequencer) - written in Processing.org by Unearthed Music recording artist and AudioCookbook.org founder John Keston, analyzes video input and converts it into a sequence of musical information in real-time. Each frame is processed to find the brightest pixel. The x coordinate is converted into pitch while the y coordinate is translated into dynamics. The application was also designed to use probability distributions on pitch and durations.
- BoxySeq - an experimental JACK MIDI application whose functionality lies somewhere between sequencer and arpeggiator but can't be said to be either. It operates using a customized bin-packing-like algorithm based upon the behaviour of the Fluxbox window manager.
- xwinmidiarptoy - an experimental BASH script which utilizes X and whichever window manager you happen to be using within X. xwinmidiarptoy is a MIDI sequencer which works by repeatedly opening xterm terminal windows within X and maps the position of the terminal window on the desktop to a MIDI note and velocity. Each xterm hangs around while the note plays, and then some specified time afterwards before disappearing again. Different arpegiating patterns can be generated by placing the windows of other software programs in varying positions within the desktop and thus (if you are using a window manager that works this way) blocking the script from producing certain notes.

Such a target is."
- BloqSeq - switches between four 8-step sequences using an 8-step pattern.
- Series - a MIDI sequencer based on the concept of serialism. Two separate counters can be assigned to three gate sequences and three modulation sequences. With three LFOs, four random step generators and performance controls, Series is capable of generating and modulating intricate arpeggios and rhythms.
- MiniSeries - a smaller, different version of Series. Miniseries has one modulated counter that progresses through eight MIDI note assignments. Three LFOs and a variety of performance controls make MiniSeries capable of generating a wide array of sequences.
- Hex - a multi-track MIDI sequencer that facilitates music composition in microtonal tunings. It integrates seamlessly with our DT-enabled synthesizers, or with any standard MIDI synthesizer. It can also be used in conjunction with a digital audio workstation such as Pro Tools, Logic, Cubase, or SONAR. Hex uses a lattice roll in place of the traditional piano roll. This enables unfamiliar microtonal scales to be intuitively visualized, and their tuning to be dynamically manipulated. The light buttons/lanes can be thought of as generalized "diatonic" notes, and the dark buttons/lanes as generalized "chromatic" notes. - Windows/macOS

- Sequetron - a program with a twist; designed as a live instrument for hands-on use, all played & controlled from where your hands are - the music keyboard. It runs from switch-on with no interaction, and converts the simplest MIDI keyboard or device into a multi-track recording, playback & looping instrument. It has sequencer-like functions but is radically different to other programs as it is completely controlled using series of music notes called command sequences. There is no difference between commands and music - they are all sequences, hence the name... it can even control itself. Windows. Shareware/$.
