Slower free download: Kontakt Tape Library

If you're trying to get that genuine, warbly tape sound into your Kontakt library without hunting down physical machines, Slower handles it by giving you 65 sources recorded to real tape and played back at half-speed. This free download captures the specific character of four different tape decks, so you get analog warmth and imperfections baked right into the samples.

The core idea is straightforward: they recorded a wide range of sound sources to tape, then played them back at half speed to pitch everything down one octave. This isn't just a digital pitch-shift; the process runs the audio through actual tape machines, which adds natural compression, saturates the low end, and imparts those flutter and wobble characteristics that are hard to fake. You end up with sounds that are thicker, mellower, and feel like they came from a dusty reel.

The Tape Machines

This library’s character comes from the four specific machines used. Each of the 65 sound sources was recorded through all four, giving you distinct tonal options.

  • Studio: Uses the Studer A812 and Revox PR99 machines. This is your high-fidelity, professional studio tape sound.
  • Portable: Uses the Uher 4400 Report IC and Uher 4400 Report Monitor. Expect a grittier, more lo-fi character from these portable recorders.
  • Cassette: Uses the Tascam Portastudio 424mkiii. This gives you the familiar, saturated sound of a 4-track cassette deck.
  • Dictaphone: Uses the Sony M650v. This is the most degraded and narrow-sound of the bunch, full of noise and mid-range focus.

Sound Sources & Playback

You get 65 different sound sources to work with. The key process is that all recordings are played back at half-speed, pitching them down one octave from their original recording. This enhances the low-end frequencies and creates a naturally thicker, mellower tone. You can also reverse samples for instant atmospheric textures.

Shaping & Modulation

The instrument provides a full set of tools to shape the tape sounds beyond the initial recording.

  • Amp Envelope: Standard ADSR controls for amplitude.
  • LFOs: For adding cyclical modulation to parameters.
  • Modulation Envelope: A dedicated envelope for modulating other targets.
  • Step Modulator: A sequencer for creating rhythmic parameter changes.
  • Aftertouch: Allows you to map aftertouch from your MIDI keyboard to various parameters.
  • Macro Controls: Three macro knobs let you link and control multiple parameters at once for quick, broad changes.

The Effects Chain

A customizable five-slot FX chain is included, loaded with 27 built-in effects. You’ll find delays, distortions, reverbs, and filters here. This lets you further degrade, space out, or sculpt the tape sounds directly within the instrument. Separate noise and wobble controls also let you dial the classic tape artifacts in or out.

Technical Specifications

This is a Kontakt instrument library. You will need a full version of Native Instruments Kontakt (version 6 or later) to use it. The library does not run in the free Kontakt Player.

Who Is This For?

This fits a few clear scenarios. It’s useful for hip-hop producers looking for thick, pitched-down loops and one-shots with authentic grit and low-end weight that digital processing alone can’t provide. It also works for ambient and electronica composers who want a starting point of degraded, wobbly textures and pads that already have movement and character, ready to be fed into their own effect chains. If you specifically want the sonic imprint of different physical tape machines without the hassle, this library does that work for you.

Limitations

The main requirement is that you must own the full, paid version of Native Instruments Kontakt. It will not function in the free Kontakt Player. This limits its accessibility for those who only use the Player. While it covers a lot of ground, the sound palette is inherently colored by the half-speed tape process—it’s specialized for creating those darker, degraded, and pitched-down textures.

Final Verdict

Grab this free download if your goal is to access a broad library of sounds with genuine, varied tape character for Kontakt. You get the practical benefit of 65 sources processed through four different tape machines, which is a lot of specific texture to work with. The built-in modulation and effects let you tweak things further without leaving the plugin. Just know that you need the full version of Kontakt to open it. If you work in hip-hop, ambient, or electronica and want an efficient way to add analog tape warmth and half-speed depth to your tracks, this is a straightforward tool for that job.
