Getting Started

When you launch Aftertouch for the first time, you’ll be greeted with a landscape view of a sparse grid. Four rows tall, and five columns wide.

A the bottom left, you’ll see the lowest note, 60, middle C. Above that, you’ll see 65, the F a fourth above middle C.

Go ahead. Indulge yourself. Tap on the F pad lightly. Tap it again, a bit harder. Notice the pink ring change in size based on how hard you initially strike the note. The pink ring shows the note’s velocity.

Tap again and hold the note. Press a bit harder. And a bit softer. Watch as the blue rectangle shrinks in response to your touch. The blue rectangle show’s the note’s pressure.

Slide your finger up the screen. Hear the timbre of the sound change.

Now slide it to the right. Hear the pitch bend up.

That’s it, really. Those are the basics. Everything else below is about customizing the grid, picking a MIDI destination, and choosing which parameters change in response to your expressions.
