Arabic quarter-tones & transpose on any keyboard, from your phone. Maqam sends the exact MIDI your arranger or synth understands, so Middle-Eastern scales and live key changes work in real time — no computer, no extra box.
Authentic Arabic & maqam
scales, sent as native MIDI.
Change key live from the
phone — no menu diving.
Arrangers, workstations
and synths, model by model.
Wired or wireless —
connect and play.
These are the exact adapters and cables we use with Maqam on stage — tested at real gigs. Every item has a buy link.
iPhone → genuine Apple adapter → USB hub → two MIDI-USB cables → two organs at once.
Zero cables between the phone and the keyboards. One adapter per keyboard — playing two keyboards? Get two.
iPhone + Android
Plugs into the keyboard's round MIDI sockets and talks to the phone over Bluetooth — no cable at all. Works on every keyboard with 5-pin MIDI, on iPhone and Android.
💡 On the keyboard, turn Clock Send OFF (your model's setup guide shows where) — and set the adapter to its blue (BLE) mode.
The most reliable connection. Android needs no special adapter — any simple USB-C hub does the job. iPhone must use Apple's genuine adapter.
iPhone + Android
Most arrangers have a square USB-B socket for MIDI — this is the cable that goes into it. Get a short one with good shielding; the cheapest ones can lose data mid-song.
Android
Android needs no special adapter: any simple USB-C hub works. Plug the keyboard's USB cable into the hub and the hub into the phone. Two keyboards? Plug in both cables — Maqam drives both at once.
iPhone
iPhone 15 and newer (USB-C): Apple's USB-C to USB adapter (pictured). Older iPhones (Lightning): Apple's Camera Adapter. Only iPhone needs an Apple adapter.
⚠️ Buy the genuine Apple one. Cheap copies look identical but silently drop the tuning data Maqam sends — we learned this the hard way.
Older keyboards without a USB-MIDI port need one converter between USB and the round MIDI sockets.
iPhone + Android
Converts USB to the round 5-pin MIDI plugs. Connect it to the phone through the USB-C hub (Android) or Apple adapter (iPhone) above.
⚠️ Avoid the cheapest no-name MIDI cables — many of them drop the tuning messages Maqam sends. The Roland UM-ONE mk2 is proven.
Each guide tells you exactly which switches to turn on in your keyboard's own menus so it accepts the tuning and transpose Maqam sends.
