# Tactus

> Your studio, at your fingertips.

Tactus turns your iPhone or iPad into a wireless control surface for your music software. Pair once over Bluetooth and your device becomes faders, knobs, pads and keys — ready to play.

Tactus turns your iPhone or iPad into a wireless control surface for your music software. Pair once over Bluetooth and your device becomes faders, knobs, pads and keys. Four pages: an everyday panel of faders, knobs and an XY pad; a full-width velocity keyboard with pitch bend and modulation; sixteen pads in a drum-rack layout; and an eight-channel mixer with volume, pan, mute, solo and record arm. Ten fingers are tracked at once, velocity comes from where you strike, and every control can be taught to anything in your DAW in seconds. No account, no subscription, nothing collected about you.

## Built to be played

### Four surfaces

Faders, knobs and an XY pad for the controls you reach for most. A full-width velocity keyboard. Sixteen pads in a drum-rack layout. And an eight-channel mixer with volume, pan, mute, solo and record arm.

### Ten fingers at once

Ride two faders, hold a chord and hit a pad. Every touch is tracked on its own, so nothing drops out from under you.

### Velocity where you strike

Play near the top of a key or pad for a soft note, toward the bottom for a hard one. The same pad can whisper or shout.

### Pairs over Bluetooth

No cables, no dongles, nothing extra to install on your computer. Prefer Wi-Fi or a cable? Those work too, with nothing to reconfigure.

### Fits your setup

Play, stop and record work straight away in software that expects them, and every other control can be taught to anything you like in seconds.

### Yours alone

No account, no subscription, nothing collected about you. Tactus works entirely offline.

## What you'll need

- A computer running music software that accepts Bluetooth MIDI. Macs pair in a couple of taps.
- iOS 17 or later.
- iPhone plays in landscape. iPad works in any orientation.

Tactus is a controller: it plays your instruments and moves your mixer. The sound comes from the music software you already use.
