" Greta Job circuit(MD-BT01 in/out) LPK25 W-SS + LPD8 WLESS works great "
Andrej Zbro
" I don't normally buy apps but I'm so glad I did. "
Nick Procenko
" Works great with my CME H4MIDI and WIDI Core! "
Guido K
" This is mad scientist level of MIDI functionality on Android! Using it to control Flip Sampler on an iPad Pro, with Imaginando LK running on the Pixel 6 Pro, via MIDI Hub's BLE Host Server feature which says Experimental but works great and has minimal latency when compared to RTPMidi over wifi! "
César Omar Posada García Satamusic
" My God, I feel like I've finally made it out of the MIDI BLE to Windows to RTP to Android to Raspberry Pi valley...this is amazing, rock solid with very little latency. Thank you so much! "
Sean Norris
" This was worth the purchase! I needed to connect a USB MIDI keyboard to a Behringer JT-4000 without hassle. All it took was a USB hub and this app, and my daughter happily explored the classic supersaw sound + filter cutoff in the living room. Thanks for making it possible. PS: dark mode would be nice but not a must. 5 stars with or without. "

FAQ
Quick answers
Most‑asked questions at a glance.
How do I connect my keyboard to multiple apps at once?
Create a bridge by swiping from your USB or Bluetooth keyboard input to multiple virtual output ports. Each app can then connect to a different virtual port, receiving the same MIDI data simultaneously. Learn more about virtual ports.
Can I run MIDIHub in the background?
Yes. MIDIHub continues processing while you use other apps, with notifications for connection issues. For best results, disable battery optimization.
What's the latency like for live performance?
USB offers the lowest latency, BLE works well for many users, and RTP‑MIDI over WiFi is solid on good networks. MIDIHub processes messages in real time for live playability.
Can I save different setups for studio vs live performance?
Yes, use Presets to save complete configurations (connections, bridges, rulesets). You can also auto‑load a default preset on app start. Learn about presets.
