Reason Free Review

In this Reason Free review, i tested Reason Studios’ massive new release in my studio sessions.

I installed this completely free edition of the legendary Reason Rack plugin across multiple DAWs. It features 15 legendary devices, including instruments, creative effects, utilities, and MIDI generators.

Review Overview

The 15 Included Devices in Reason Free

Reason Free does not give you stripped-down demo units. It includes 15 full-featured devices from the Reason ecosystem.

1. Instruments

• Europa Wavetable Synthesizer: Europa is Reason’s flagship wavetable monster synth.
  
  When I initialized a clean patch and began morphing the wave engines, the wavetable visualization on screen updated instantly with zero graphic lag. It effortlessly handled everything from aggressive EDM saw stacks to shimmering ambient textures.
  
  
• Kong Drum Designer: An elite 16-pad drum machine.
  
  I loaded up a factory 808 kit and used the per-pad physical modeling to tighten up the decay of the kick drum, which gave my trap beat an incredibly punchy low-end.
  
  
• Monotone Bass Synthesizer: A dedicated analog-modeled monophonic synth designed specifically for deep sub-bass lines, squelchy acid bass, and punchy synth leads.
  
  Its simple interface makes this hardware a reliable choice for quick, heavy sub-bass during studio sessions.
  
  
• ID-8 Multi-Instrument: A lightweight, fast multi-instrument device packed with essential acoustic pianos, electric pianos, organs, strings, brass, and utility drum kits.
  
  These simple electric pianos and acoustic strings deliver a classic vibe that sits well in busy mixes.
  
  
• MIDI Out Device: You can route MIDI CV information out of the rack to external hardware or secondary DAW tracks.
  

2. Effects

• Scream 4: One of the most famous saturation and distortion plugins in audio history. It features 10 distortion algorithms (including Tube, Tape, Fuzz, Overdrive, and Digital) alongside body EQ filters.
  
  I inserted a clean digital drum loop into the ‘Tape’ mode and increased the drive parameter. This adjustment immediately added a warm, cohesive harmonic glue, effectively softening the harsh transients of the snare.
  
  
• The Echo: A pristine tape and digital delay unit featuring pitch-shifter feedback loops, ducking, auto-pan, and analog tape wobble.
  
  I automated the analog tape wobble parameter on a clean vocal track, and it instantly dialed in a beautifully unstable, vintage lo-fi character that gave the chorus a massive depth.
  
  
• RV7000 MKII Advanced Reverb: A high-end algorithmic reverb offering room, hall, plate, impulse response (convolution), and gated reverb models.
  
  In my mixing tests, the long decay times produced a smooth, dense reverb tail with no metallic artifacts.
  
  
• Audiomatic Retro Transformer: You can add instant retro lo-fi flavor across Tape, Vinyl, VHS, Telephone, and Radio modes using a single knob.
  
  I applied the Telephone and Radio algorithms to background vocals to isolate the mid-range frequencies against the main lead.
  
  
• MClass Maximizer: A mastering-grade brickwall limiter and loudness maximizer with soft-clip capabilities to keep your rack outputs clean.
  
  I tested it on a master chain; it boosts loudness transparently while keeping transients up to 3–4dB of gain reduction.
  

3. Utilities

• Combinator: The heart of Reason’s workflow.
  
  The Combinator lets you combine multiple synths, drums, and effects into a single custom instrument with macro controls.
  
  I used it to layer a heavy Monotone sub-bass under an evolving Europa pad. Mapping a single macro knob to both filters worked flawlessly; it unlocks massive sound design possibilities.
  
• Pulsar Dual LFO: A flexible modulation generator that routes complex low-frequency oscillation curves to any device parameter via CV cabling.
  
  I cabled Pulsar’s LFO 1 output directly into Europa’s main filter cutoff on the back panel, and the modulation was perfectly smooth!
  
  
• Spider Audio Merger/Splitter: Splits or merges audio signals for parallel processing chains.
  
  I used it to split a synth line so I could heavily distort the high frequencies while leaving the low-end perfectly clean.
  
  
• Spider CV Merger/Splitter: Splits or merges Control Voltage (CV) modulation signals to control multiple knobs from a single modulation source.
  
  During my routing tests, this was a lifesaver for tying the movement of three separate instruments back to a single master clock source.
  

4. MIDI Player Devices

• Scales & Chords: A transformative MIDI FX tool. It locks your keyboard to any selected musical scale and automatically generates complex, professional chord progressions from single keys, with no music theory required.
  
  I put this to G-Minor and instantly got an incredible chord progression that started my production workflow.
  

The Back-Panel Cabling

The feature that makes Reason Free vastly superior to standard plugin bundles is its virtual cabling system.

By pressing the Tab key on your keyboard (or clicking the flip button), the entire virtual rack spins around 180 degrees to reveal an interactive back panel.

➤ What You Can Do Behind the Rack:

• Sidechain Ducking: Route audio from Kong’s kick pad into the sidechain input of Scream 4 or RV7000 to automatically duck reverb tails whenever the kick hits.
  
  
• LFO Modulation: Cable Pulsar’s Dual LFO outputs directly into Europa’s wavetable position or Scream 4’s distortion drive for breathing, evolving textures.
  
  
• Parallel Audio Splitting: For example, you can use Spider Audio to split an ID-8 piano signal into two paths. Process one signal clean and drive the second through heavy distortion and pitch-shifted delay before blending them back together.
