MidiBus 4+

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!!!!!!!!

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.

I've been trying to get auria and other apps that claim to be able to run midi clock to actually do what they claim. My use is in hip hop syncing hardware sequencers/workstations to auria in order to record each track of music separately but staying in sync. No apps on the market seem to be able to do this reliably at all. My tracks were drifting all over the place, the midi on most of these daws is terrible for such a thing... BUT MidiBus came through, I'm actually able to load(record) my music up track by track syncing to hardware without any problems. This app ran very stable and sent good stable clock to auria effectively letting auria use minibus as it's midi clock just as if it was built in. Great Job to the secs I hope to see more from you guys, Thanks!

P.s I can confirm that this worked with a behringer istudio is202 ipad interface and a Korg Krome workstation .
