Reason is a digital audio workstation for creating and editing music and audio developed by Swedish software developers Propellerhead Software. It emulates a rack of hardware synthesizers, samplers, signal processors, sequencers, and mixers, all of which can be freely interconnected in an arbitrary manner. Reason can be used either as a complete virtual music studio or as a set of virtual instruments to be used with other sequencing software in a fashion that mimics live performance. ==Overview== Reason 1.0 was released in December 2000. The program's design mimics a studio rack into which users can insert virtual devices such as instruments, effects processors, and mixers. These modules can be controlled from Reason's built-in MIDI sequencer or from other sequencing applications such as Pro Tools, Logic, FL Studio, REAPER, Digital Performer, Cubase, Sonar, and GarageBand via Propellerhead's ReWire protocol in the 32-bit versions of these programs. Since the release of version 6 Reason supports ReWire with 64-bit hosts. As of version 7.0.1, devices available include: *Subtractor: a subtractive synthesizer *Malström: a graintable synthesizer (granular synthesis + wavetable synthesis)〔 *NN-19: a simple sampler, which loads pre-recorded instrumental and vocal sounds *NN-XT: an advanced sampler, which features the option of tweaking the various modulation, oscillation, and filter parameters of a preloaded sample or patch *Dr Octo Rex: a loop playback device, which slices prerecorded samples *Redrum: a sample based drum machine with a step sequencer *Thor: a semi-modular synthesizer which features, among others, wavetable synthesis,〔 frequency modulation synthesis (FM), and phase distortion synthesis *Kong Drum Designer: a 16-pad drum synthesizer with analog synthesizers emulating the classic generators of drums like the Roland TR series, physical modelling drum synthesizers and sampler akin to the Akai MPC series. *Neptune: A voice synthesizer and pitch correction tool, capable of Vocoder-like polyphonic voice synthesis as well as robotic, AutoTune-like pitch adjustment and more subtle pitch corrections.〔(Reason 6 - Neptune )〕 *Alligator: A triple filtered gate, sometimes known as a "trance gate". Alligator splits an incoming signal into three signals, which are then gated and filtered using lowpass, bandpass and highpass filters on each respective channel. Alligator also is capable of adding delay, distortion, phasing and stereo panning effects to each channel, and each of the filters can be modulated with a filter envelope embedded in the unit.〔(Reason 6 - Alligator )〕 *Pulveriser: A multi-purpose piece of virtual hardware that combines compression, distortion, filters, tremolo, parallel signal processing and an envelope follower.〔(Reason 6 - Pulveriser )〕 *The Echo: An echo unit based on tape echo and delay.〔(Reason 6 - The Echo )〕 * External MIDI Instrument: A device which allows for MIDI output from Reason to an external MIDI instrument Sounds from these devices can be routed via either of two mixing devices or simple merging and splitting utilities. Effects include distortion, reverb, chorus, a vocoder, and mastering effects. The Combinator device, introduced in Reason 3.0, allows users to combine multiple modules into one. Another device connects Reason to Propellerhead's (now discontinued) ReBirth RB-338. Reason's interface includes a Toggle Rack command, which turns the "rack" around to display the devices from the rear. Here the user can route virtual audio and CV cables from one piece of equipment to another. This cable layout enables the creation of complex effects chains and allows devices to modulate one another. This offers flexibility in the way that is familiar to users of physical electronic music hardware. For example, Redrum's main outputs could be connected to a single channel of the mixing desk, or instead each of its drum sounds could be routed to a separate EQ before sending them to separate channels in the mixer, or rather than audio output the channels of the ReDrum could be used to trigger the gates of an Alligator via CV. The user can always choose where to draw the line between simplicity and precision, allowing the software to remain useful at various levels of knowledge on the user's part. Reason 6 introduced audio recording (by incorporating Record), turning it into a digital audio workstation. It does not support third-party plug-ins, being one of the few software sequencers to lack VST support. This has been a frequent cause of criticism, although it also contributes to the product's stability. However, Reason 6.5 introduces rack extensions, which are rack instruments and signal processors that may be developed by third parties. A stripped-down version of Reason known as Reason Adapted, which restricts the user to a limited number of devices, is packaged as bonus software with other audio software such as Pro Tools LE and ReCycle. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Reason (software)」の詳細全文を読む スポンサード リンク
