The main Tsukuyomi walkthrough will land here.

One instrument. One window. From the first hit to finished drums.

The problem

Your drums shouldn't need five plugins.

A sampler for the sounds. A sequencer for the pattern. Another plugin for compression, another for saturation, another for space. Somewhere between the third window and the fourth, the idea you had five minutes ago is gone.

Tsukuyomi keeps the whole process in one place: pads, sequencer, sound design, mixer, effects and mastering in a single window.

Play it

Load a kit. Start making noise.

Hit pads with a MIDI controller, your keyboard or the on-screen grid. Layers respond to velocity, choke groups keep hats behaving, and 32 voices leave room for fast rolls.

Build the sound

Every pad holds three sample layers you can stack, cycle, randomize or map to velocity. Shape each one with a full envelope, filter, drive, pitch, reverse and pan. You're not picking a drum, you're building one.

Sequence it

Build the rhythm directly inside Tsukuyomi.

Program in 4/4, 3/4, 5/4, 6/8, 7/8 and 2/4, then shape swing, groove and Euclidean fills until the pattern moves the way you want.

  • Drag whole beats

    Move complete patterns into the groove, then keep shaping them.

  • Drag individual pieces

    Place single kicks, snares, hats and percussion exactly where they belong.

  • Start from categorized presets

    Browse by style, pull in a starting point and make it your own.

  • Build, customize, drag

    Combine the parts, adjust the feel and rearrange without leaving the sequencer.

Make every hit matter

A pattern should feel human.

A pattern shouldn't sound mechanical just because you drew it with a mouse. Select any step and shape what happens inside that hit.

VELOCITY

Softer or harder.

PROBABILITY

A chance of playing instead of a guarantee.

MICRO-TIMING

Push or pull a hit off the grid.

RATCHET

Up to 8 repeats per step.

PITCH

Up to ±24 semitones.

CONDITIONS

Every 2nd, 3rd or 4th loop, or fills only.

The pattern stops being a grid. It starts behaving like a performance.

Four scenes, one track

Build a track, not just a loop.

Build a groove, a stripped-back verse, a variation and a fill. Launch them by hand or chain them. Scenes switch on the downbeat of the next loop, so your drums evolve without stopping the music.

Your kit

Your kit. Your rules.

Start with the factory library, then drag in your own WAV, AIFF or FLAC files. Swap the kick, layer the hats, lock the sounds you love and randomize the rest. Happy accidents are part of the workflow.

Then mix the kit

Every pad. Every move. Your mix.

Shape all 16 pads independently, then bring the kit together through the master bus.

  • Independent channel control

    Set volume, pan, mute and solo on every pad.

  • Shared effects

    Send each channel to delay, reverb, chorus or parallel compression.

  • Whole-kit balance

    Keep the master simple or print a fully custom drum mix.

Routing

One piece. One channel. No compromises.

Send every piece directly to its own channel in your DAW, or keep the full kit together when the mix calls for it.

  • Direct per-piece channels

    Kick, snare, hats and percussion each reach the DAW on their own track.

  • Independent processing

    Shape, compress and automate every drum piece without the rest of the kit.

  • Master or multitrack

    Print the whole kit or print only the pieces that need attention.

ISI AUDIO Architectural Models

Three original EQ characters.

Switch on Analog and choose an architectural model built to give the kit its own character.

ISITECH

A boost-and-cut program-style EQ. Shape the low end, open the highs, find that big-but-tight feeling.

Compress the right drums

Not the whole kit.

Give the kick more weight, crush the snare and keep the hats dry. Three parallel slots let each piece move on its own terms.

Every pad feeds each compressor independently, then blends back against the dry kit.
