Psycle is a free, Open-Source, music creation program that offers an easy way to create your own music, fast, and with high quality.
Psycle uses a classical tracker interface (a text grid of notes which are sequenced one after the other), coupled with modularity (plugins) that allow to extend the sounds that you get from it.
It supports three ways to get sound: its own native format, the VST Plugin standard, and recorded .wav samples using the sampler machine.
Notes are entered in patterns, where you can also use commands (plugin specific, or global), as well as automating parameters via the mcm and twk commands. These patterns are then organized in a linear sequence, which becomes the song order.
Main features:
VstSeq is a simple "piano roll" style pattern sequencer VSTi host actually designed to run as a plugin in Tuareg 2 but it also has a stand alone version.
Features:
MusE is a multitrack virtual studio for Linux that has support for sequencing of both MIDI and audio and has, among other things, support for LADSPA, Jack and ALSA.
Some Highlights
And the most important feature for a free application:
GPL Licensed.AirRack is a live environment for those who make sound effects for TV program and other live performance.
AirRack provide you the following racks:
You can control the AirRack with your MIDI controller and your computer keyboard. Both English and Chinese versions are available.
It is designed as a modular system. The main application provides a mixing console, while the audio sequencer, live audio input and so on are loaded as separate PlugIns.
Kristal Audio Engine is FREEWARE for personal, educational and non-commercial use.
Features:
The following Plug-ins are included in the Kristal package:
Kristal Waver
Kristal LiveIN
Kjetil Matheussen's VST server system has evolved to include the following components:
SynthFont is a free/donationware tool for playing/rendering MIDI files using SoundFonts and other similar sound sources (WAV, DLS, GIGA and also VST Instruments).
SynthFont is intended to mimic the behavior of SoundFont compatible hardware/soundcards like SoundBlaster Live! or Audigy and SynthFont is (almost) modulator aware, which Live! is not. But SynthFont is more. It provides an interface into the SoundFont structure and has basic editing capabilities. It also displays various data about the loaded MIDI file through the piano roll and the event list. Finally, there is a simple playlist feature for storing the files you are currently working on.
SynthFont also supports VST effects - there are 17 busses in all: one master bus and 16 channel busses.
VSTSynthFont
VSTSynthFont (VSF), a separate VST instrument version of SynthFont is also available. It is a completely independent module, which you can use without SF installed. It does not have any of the SoundFont tools SF has, nor can it display any MIDI information as it does not handle MIDI files.
SAVIHost is a derivative version of VSTHost that can be used to make any VSTi run like a standalone application.
This offers two major advantages:
For use just rename SAVIHost.exe to the corresponding VSTi.dll e.g. if there is abc123.dll rename SAVIHost.exe to abc123.exe and this will run the VSTi.
DarkWave Studio is a modular virtual studio, similar to the tracker / modular studio Buzz. It allows you to load various machines such as virtual instruments and effects and connect them in a modular and straightforward fashion. DarkWave can load VST instruments and effects and it can also load machines using the DarkPlug API, which was custom made for DarkWave.
DarkWave natively supports both x86 (32-bit) and x64 (64-bit) versions of Windows with native binaries compiled for each platform. The x86 and x64 versions can each only load plug-ins for that platform, i.e. the x64 version only loads 64-bit VST and DarkPlug plugins.
DarkWave supports multiple processors, with an aggressively multithreaded audio path that can utilize multiple processors or cores by multithreading. Apparently the program soars on a Pentium D system with Windows XP 64-bit Edition.
The following plugins are included with DarkWave:
MultiFXVST is a free Windows effect chainer that loads as a VST effect in your VST host and can also host, and chain, VST effect plug-ins itself.
Features:
Main features:
EffectChainer is a DirectX and VST capable universal wrapper and multi-effect rack. With EffectChainer you can load, edit and chain as many DirectX and VST plug-ins you want. EffectChainer itself can be used as a plug-in in any host application supporting DirectX or VST.
Features:
Rosegarden is a professional audio and MIDI sequencer, score editor, and general-purpose music composition and editing environment.
Rosegarden is an easy-to-learn, attractive application that runs on Linux, ideal for composers, musicians, music students, and small studio or home recording environments.
Rosegarden does not provide a built-in software synthesizer, so it requires a hardware MIDI synthesizer, a soft synthesizer such as FluidSynth or TiMidity++, or a synthesizer plugin in order to make any sound from MIDI compositions. Recent versions of Rosegarden support the DSSI software synthesizer plugin interface, and can use some Windows VST plugins through an adapter.Jokosher is a simple and powerful multi-track studio. Jokosher provides a complete application for recording, editing, mixing and exporting audio, and has been specifically designed with usability in mind.
