Ecasound is a software package designed for multitrack audio processing. It can be used for simple tasks like audio playback, recording, and format conversions, as well as for multitrack effect processing, mixing, recording and signal recycling. It supports a wide range of audio inputs, outputs, and effect algorithms. Effects and audio objects can be combined in various ways, and their parameters can be controlled by operator objects like oscillators and MIDI-CCs. A versatile console-mode user interface is included in the package.
Songwrite is a tablature editor. It supports many string instruments in addition to traditional staff notation. You can edit tablature (guitar, bass, banjo, etc.) and staff notation, add lyrics, create your own songbook, play your partitions, print your partitions and your songs, automatically convert staff notation to tablature and vice-versa, export songs to many formats (PDF, MIDI, ASCII tablature, GNU Lilypond, LaTeX, PostScript, etc.), and import Guitar Pro 3/4 files (experimental).
Swami is an instrument patch file editor using SoundFont files that allows you to create and distribute instruments from audio samples used for composing music. It uses FluidSynth, a software synthesizer, which has real time effect control, support for modulators, and routable audio via JACK. This project supersedes the Smurf SoundFont Editor, and is an entire object-oriented rewrite of it. The supporting libraries are GUI-independant and can be used in your own programs for doing SoundFont manipulation.
Pymprovisator is a program for jazz musicians. Jazz music is based on improvisation and this program is intended to help musicians to improvise. The user sets the song parameters and the program generates a MIDI file with an adequate accompaniment. It emulates the program Band in a Box from PG Music. You can think of it as the electronic version of the books/CD from Jamey Aebersold.
PyChoReLib is a Python library which transforms lists of notenames to a chordname. The system uses built-in music theory knowledge to make it easy and quick to add support for new chord types. Its features include interval recognition, scale recognition, and demo chord recognition using real-time input from MIDI devices.
OrganDesigner is a graphical tool for editing and configuring virtual pipe organs. OrganDesigner can read SoundFont files and can both read and write organ description files for use by the virtual organ MIDI player GENPO. OrganDesigner users can copy, move, and delete stops, both within and between divisions; use the Stops Editor to change a stop's name, MIDI bank, program, and velocity; use the Divisions Editor to make new divisions, change a division's name and MIDI channel, change the order of divisions, and delete divisions; use the Couplers Editor to add, modify, and delete couplers; use the Pistons Editor to add, modify, and delete combinations, and to store and recall the stops set for each piston.
Fripp is a music composition environment that uses a spreadsheet metaphor for entering music and manipulating it with built-in and user-created functions. It supports MIDI playback and recording, and displays music in common notation. Scores can be exported to Mup format for high quality printing. The core program is written in Python, and the user interface is implemented using the wxPython toolkit.
Schnolgo is a musical composition system. It has a number of unique features, including a way of handling polyrhythmic timing which provides a flexibility one cannot easily achieve with traditional sequencing programs or sound programming environments. Currently, Schnolgo is in the form of a Python package, and its main output format for compositions written in it is MIDI.
Midi Music Flash Cards is a music sight-reading trainer. It generates flashcards dynamically according to "modes" as specified through a handful of menus across the top. In auto-mode it continuously generates flashcards, with controllable time intervals between MIDI playback and a further time interval between displaying written feedback about the key and notes.
