FL Studio, formerly known as FruityLoops, is a fully featured, open-architecture music creation and production environment for PC. No extra software is required to produce any style of music, as the complete set of instrument and studio tools is included in the cost of the package. With the included plugins, sounds and tools the user can create complete songs, as well as backing tracks, loops and sizzling beats. Completed songs can be saved to WAV, MP3 or MIDI or .ZIP or native project formats (.FLP).FL Studio utilizes MIDI and DirectSound (internal mixing), 16-bit 44KHz stereo output, and 32-bit floating-point internal mixing. You'll also get support for VST plug-ins, as well as individual panning, volume, pitch, mix, resonance, and cutoff on each note.

FL Studio is the most complete virtual studio currently available. It will play any sample file (wav), generator (softsynth), VSTi & DXi) or midi instrument you feed it. You will be creating wav, mp3 or midi songs or loops only minutes after launching it.
