The Image Line FL Studio 21 Signature Edition is a complete software music production environment that includes FL Studio 21 Producer Edition along with the Signature plug-in bundle. It delivers a full suite of music creation features including audio recording and editing, MIDI piano roll and step sequencing, live performance mode, and multitouch support. It also includes over 80 software synthesizers and effect plug-ins.

This latest update introduces faster and more precise audio editing, improved content discovery, control over the mood of the DAW, and even more inspirational, creative tools. The software offers full Mac OS X and macOS support (10.11 or later), unlimited time signature changes, consolidate clips (freezing), playlist arrangements, full plug-in delay compensation, and a redesigned tool bar. FL Studio 21 Signature Edition has support for AU and VST 64-bit, DX, and FL Native plug-in formats, and it can be hosted in other DAWs as a VST or connected through ReWire. Both Mac and Windows versions are cross-platform compatible, allowing for seamless sharing and collaboration.

FL Studio 21 offers a host of advanced audio recording and editing functions that you can use to capture and fine tune your musical ideas. It allows you to record an unlimited amount of audio tracks simultaneously, only limited by the power of your computer and the amount of inputs on your audio interface. Once recorded, you can manipulate your audio with Edison, FL Studio’s integrated wave editor that provides a broad palette of functions such as spectral analysis, convolution reverb, noise reduction, loop-construction tools, and more. Using the playlist function, you can arrange your audio and perform other editing tasks such as time-stretching, pitch-shifting, beat-slicing, cropping, and more.

In addition to audio recording and editing, FL Studio 21 provides advanced mixing and routing options that allow you to create complex, polished productions. Allowing for up to 125 channels, the mixer can be used for leveling, panning, creating submixes, and adding effects to your audio. Each channel of the mixer is equipped with a parametric EQ and can hold up to 10 effects (VST, DX, or FL’s Native format). Choose from more than 40 effects including maximization, limiting, compression, delay, distortion, equalization (graphic and parametric), filtering, phasing, flanging, chorus, vocoding, and reverb. Furthermore, the mixer includes four dedicated send channels that provide the ability to sidechain inputs to multi-input effect plug-ins.

FL Studio 21 offers a multitude of MIDI recording and sequencing functions that are centered around its piano-roll and trademark step sequencer features. Use either of these powerful tools alone or in combination with one another to record your musical performances in either pattern or track sequencing mode depending on your personal workflow. Choose from a selection of over 30 software synthesizers covering acoustic/synthetic bass, electric guitar, multisampler tools including piano and strings, general sample playback, and beat-slicing (with Rex 1 and 2 support).
