Midi-Morf
Wireless Midi Controller
Free
Seven MIDI controllers you'd actually want, in one app.
MidiMorf is a suite of expressive iOS controllers with a deep 32-voice synth to play them through. Grab your phone, put on headphones, and you're jamming in ten seconds. Or connect the free companion server to your Mac and turn it into a wireless
MIDI rig for Ableton, Logic, GarageBand, and any DAW that speaks MIDI.
THE SEVEN CONTROLLERS
• Morf-Pad — XY morphing pad with scale-locked notes
• Strum-Chord — Omnichord-inspired chord grid + strum plate
• Morf-Chord — 7 diatonic chord pads with per-chord XY voicing
• Rose-Chord — Orchid-inspired: hold chord types, tap the keyboard
• Dual M-Pad — two independent XY pads side-by-side
• Transport — Play/Stop/Record + Mackie Control utility buttons
• Morf-FX — XY effects pad with assignable FX buttons
TWO WAYS TO PLAY
Local mode — the built-in synth makes the sound. Headphones or a Bluetooth speaker. Never touch a computer.
WiFi mode — run the free MidiMorf Server on your Mac. Every note, CC, and transport message flies over WiFi into your DAW. No cables, no MIDI interface, no latency headaches.
THE SYNTH
32-voice polyphony. Dual oscillators (sine, triangle, saw, square) with PolyBLEP anti-aliasing plus a sub. Analog-modelled 4-pole ladder filter with resonance. Full ADSR on amp and filter. LFO. 4-slot modulation matrix routing accelerometer tilt,
velocity, mod wheel, and LFO to filter, pitch, gain, and effect parameters. Distortion, tempo-friendly delay, reverb.
MORE
• Tilt your phone — the accelerometer is a live mod source
• Custom color theme per controller
• Favorite button — long-press to assign, tap to jump
• Landscape-only, wood-frame
