TiMidity++ ~ Synthesizer & Player


TiMidity++ is a software synthesizer. It can play MIDI files by converting them into PCM waveform data; give it a MIDI data along with digital instrument data files, then it synthesizes them in real-time, and plays. It can not only play sounds, but also can save the generated waveforms into hard disks as various audio file formats.

TiMidity++ is a free software, distributed under the terms of GNU general public license.

Features:

  • Plays MIDI files without any external MIDI instruments at all
  • Understands SMF, MOD, RCP/R36/G18/G36, MFI
  • Converts MIDI files into various audio file formats: .wav, .au, .aiff, .ogg and so on
  • Uses Gravis Ultrasound compatible patch files and/or SoundFonts as the voice data
  • Displays information about the music that is now playing
  • Various user interfaces: ncurses, gtk, Win32-GUI, and others
  • Plays remote MIDI files over the network
  • Plays MIDI files in archive files
  • Displays sound spectrogram for the playing music
  • Trace playing

StudioFactory ~ Analog Modular Synthesizer


StudioFactory provides a complete virtual audio studio on your computer. It has a very powerful virtual analog modular synthesizer based on an improved version of the SynFactory synthesis engine. StudioFactory is fully compatible with SynFactory and can load all existing patch files. The synthesis engine is extended with additional modules that give access to MIDI and audio input. This makes it possible to play sounds generated by StudioFactory with an external MIDI-keyboard. With the audio input StudioFactory can be used as an standalone effect processor and provides reverb, echo and vocoder effects..

Sonic Pi ~ Live Coding Music Synth


Sonic Pi is a new kind of musical instrument. Instead of strumming strings or whacking things with sticks – you write code – live.

Sonic Pi has been designed with the aim to find a harmonious balance between three core principles:

  • Simple enough for the 10 year old within you
  • Joyful enough for you to lose yourself through play
  • Powerful enough for your own expressions

Sonic Pi is a complete open source programming environment originally designed to explore and teach programming concepts within schools through the process of creating new sounds.

In addition to being an engaging education resource it has evolved into an extremely powerful and performance-ready live coding instrument suitable for professional artists and DJs.

Cabbage ~ Audio Software Development


Cabbage is a software for prototyping and developing audio instruments with the Csound audio synthesis language. Instrument development and prototyping is carried out with the main Cabbage IDE. Users write and compile Csound code in a code editor. If one wishes one can also create a graphical frontend, although this is no longer a requirement for Cabbage. Any Csound file can be run with Cabbage, regardless of whether or not it has a graphical interface. Cabbage is designed for realtime processing in mind. It is possible to use Cabbage to run Csound in the more traditional score-driven way, but your success may vary.

Cabbage is a ‘host’ application. It treats each and every Csound instrument as a unique audio plugin, which gets added to a digital audio graph (DAG) once it is compiled. The graph can be opened and edited at any point during a performance. If one wishes to use one of their Csound instruments in another audio plugin host, such as Reaper, Live, Bitwig, Ardour, QTractor, etc, they can export the instrument through the ‘Export instrument’ option.
