PadFX4 running on iPad and iPhone in a studio

MIDI controller for iPhone & iPad

PadFX4

Make MIDI feel playable. PadFX4 turns touch into precise MIDI CC movement for synths, effects, DAWs and hardware.

PadFX4 sends MIDI — your sound stays in your instrument, effect or DAW.

Two ways to play
Four XY pads layered on one PadFX4 surface: four coloured touches, each with its own X and Y CC

XY Pad ×4

Four XY pads share one surface — each colour is its own pad. Left–right drives one MIDI CC, up–down another, so a single finger sweeps a filter and its resonance, or delay time and feedback. Give each pad its own channel, CCs and range.

4 XY pads  ·  2 CC each  ·  8 CC total
Two QUAD pads layered on one PadFX4 surface: two coloured touches, each blending its own four corner CCs

QUAD Pad ×2 PRO

Two QUAD pads share one surface — each colour is its own pad. Every corner is a CC; move toward a corner and it takes over, smoothly. One finger morphs between four sound states instead of turning four knobs.

Four fingers.
Four mappings. PRO

Play several touch slots at once, each with its own MIDI channel, CCs and range. One finger rides the filter, another the reverb send, a third the delay — all on the same surface.

Decide what happens when you let go.

Release and every mapped parameter glides back to its own return target — at the speed you set. Or hit HOLD and the values stay exactly where your finger left them.

Perfect for effect throws: push it, let go, and it settles back on its own.

FX Return Hold
Map anything

Every axis, every corner, your call.

Each axis and corner has its own MIDI channel, CC number and output range.

MIDI Learn

Move a control in your DAW or on your synth and PadFX4 captures the CC — no numbers to type.

Channel & CC

Any of 16 MIDI channels and any CC, set independently per axis or corner.

Min / Max & invert

Limit a parameter to its sweet spot, or flip its direction.

Presence CC

Optionally send one value on touch and another on release — gate an effect in and out.

Presets

A preset stores the pad type, mappings, ranges and release behavior. Build one per synth, song or set, and recall it when you need it. Changes save automatically.
