MidiBus is a MIDI clock sync generator and monitor.

Choose your bpm, time signature and MIDI destinations. Press the play button and all selected apps and devices will receive a synchronised, rock-solid MIDI sync clock source.

On the flipside, monitor the MIDI clock signals of apps and devices (including MidiBus itself) and measure how accurate and stable they really are. You might be very surprised at the results.

MidiBus is based on the iOS MIDI development library of the same name. Full details at

Thank you!!!!!!!

This app is the ONLY app I have found that will send a clock to Beatsurfer on the same device, and believe me I have tried them all! You are a lifesaver and I found before i managed to rip all my hair out!!!!!!!!

Kiss Your Synch Problems Goodbye!

If you've ever had any problems getting different synth/beatbox/DAW apps to play in time together -- and really, who hasn't? -- then you need MidiBus. Does what it says: set the tempo (bpm) and time signature in Midibus and presto! Your apps will be synched to the same, accurate clock, even the really sloppy ones.

To give but two examples: Thor and Sunrizer. Both these synths are capable of amazing sounds, and both have sequencers that refuse to play in consistent time and drift all over the place. Nothing worked, and believe me I tried lots of fixes. I just tried running Thor and Sunrizer sequences while playing Gadget (always reliable) simultaneously, all synched to Midibus, and I'm happy to report no drift whatsoever, running them for 10 minutes even.

I really want to thank the developer. Rock solid MIDI clock is absolutely essential for music creation, and it's painful to see how sloppily it's been implemented on iOS up until now. Midibus will save you many hours of tearing your hair out.

Love it!

I am a keyboard player and use this app as a midi clock master to sync all my synths. I love the tap tempo feature. One thing I would love to see that would make my life easier and probably make this app the best midi clock app out there is the capability to save Bpm lists and set lists. That way I can just click next and it would sync all my synths to the next songs's Bpm in less than one second.
