Tonecraft Tokyo — VST3 / AU Plugin

VARIANZ DRIFT

User Manual — v1.2.0

Official Website ↗

VARIANZ DRIFT is a VST3 / AU plugin combining an 8-channel drum synthesizer with a step sequencer. Instead of playing back samples, it generates the sound anew on every hit. Never the same sound twice, yet reproducible as many times as you want. That is the core concept behind this instrument, designed for EDM and techno.

1. Quick Start

  1. Load VARIANZ DRIFT on an instrument track in your DAW.
  2. Select a sound kit from KIT at the top of the window. 35 kits are organized by category.
  3. Select a rhythm from PATTERN next to it. There are 104 patterns, independent of KIT, so you can combine them freely.
  4. Press the Space key or the play button in the footer to start playback.
  5. Turn up FLUX on each channel to deepen the per-hit variation. Try moving this control first.
  6. When you find a sound you like, save it via FILE > SAVE....

KIT and PATTERN are separate lists. Switching kits leaves the pattern unchanged, and switching patterns leaves the sounds unchanged. You can start from any of the 35 × 104 combinations.

3. Parameter Details

PITCH

Sets the base pitch of the voice. The center frequency of the noise filter moves with it.

DECAY

Sets the length of the sound. Shorter values produce tighter hits.

TONE

Adjusts the overall brightness, moving both the body (core) and noise (grit) together.

SWEEP

Controls how far the pitch drops right after the hit. Higher values produce a deeper boom. This largely defines the character of a kick.

MIX

Adjusts the balance between the body (core) and noise (grit). Fully left gives body only; fully right gives noise only. For snares, set this toward the right—otherwise it will sound like a tom.

DRIVE

Adjusts the saturation applied after mixing body and noise. It lifts the tail without crushing the initial attack.

BODY / NOISE

Selects the layers that generate the core (body) and grit (noise) of the sound. Body options are SINE / FM / RESO / RING; noise options are OFF / WHITE / METAL / BURST.

FLUX

Sets the variation depth for the channel. Each hit varies in pitch, length, brightness, and timing.

WEAR / SPAN

WEAR controls how much the sound wears out as playback continues, and SPAN sets the number of bars until it is fully worn. Stopping playback resets the wear.

REPEAT

Determines how variation is handled from loop to loop.

SEED

Picks a different random draw for the variation. The same number always returns to the same variation. When you land on a variation you like, note down this number so you can reproduce it.

CHOKE

Specifies which channel is cut off when this channel triggers—for example, cutting an open hi-hat with a closed hi-hat.

OUT

Selects the output destination from MAIN, individual output, or both. Channels routed to an individual output have their PAN fixed (so you can pan them on the destination track).

4. Recommended Settings

Repeating the Exact Same Performance Every Time

REPEAT: LOCKED
SEED:   Your noted number
WEAR:   0

With these three settings, the performance stays identical across any number of loops. Recommended when exporting audio.

Gradual Movement for Live Performance

REPEAT: EVOLVE
FLUX:   40–70
WEAR:   20–35
SPAN:   16–32

When a Snare Sounds Like a Tom

MIX:      70 or higher
N EXTRA2: High (when WHITE is selected)

Deep variation never falls apart because REPEAT and SEED let you return to the exact same draw. A practical workflow is to search for a feel you like in FREE mode, note down the SEED number when you find it, and lock it in with LOCKED.

6. Installation & Uninstallation

Installation (Windows)

  1. Extract the downloaded ZIP file.
  2. Copy the VARIANZ DRIFT.vst3 folder to C:\Program Files\Common Files\VST3\.
  3. Launch your DAW and perform a plugin rescan.

Installation (Mac)

  1. Extract the downloaded ZIP file.
  2. Copy VARIANZ DRIFT.vst3 to ~/Library/Audio/Plug-Ins/VST3/, and copy VARIANZ DRIFT.component to ~/Library/Audio/Plug-Ins/Components/ (where ~ represents your home folder. In Finder, open the "Go" menu, choose "Go to Folder...", paste the path, and press Return. If the folder does not exist, create it).
  3. Open Terminal (Applications → Utilities → Terminal), paste the following 3 lines one by one, and press Return for each. If nothing is displayed, the command succeeded.
    cd ~/Library/Audio/Plug-Ins
    xattr -dr com.apple.quarantine "VST3/VARIANZ DRIFT.vst3"
    xattr -dr com.apple.quarantine "Components/VARIANZ DRIFT.component"
    If you do not run this, macOS will show a message such as "is damaged and cannot be opened" or "cannot be opened because the developer cannot be verified", preventing the DAW from loading the plugin. These commands only remove the quarantine attribute that macOS attaches to downloaded files (you must run these commands again if you reinstall or update the plugin).
  4. Launch your DAW and perform a plugin rescan (if AU does not appear in Logic Pro or other DAWs, restart your Mac).

Uninstallation

Windows: Delete the copied VARIANZ DRIFT.vst3 folder. Saved presets remain in %APPDATA%\VarianzDrift\Presets\, so delete that folder as well if you no longer need them.

Mac: Delete the copied VARIANZ DRIFT.vst3 and VARIANZ DRIFT.component files. Saved presets remain in ~/Library/VarianzDrift/Presets/, so delete that folder as well if you no longer need them.
