Hello, I'm trying to setup new gear for my live performances. I normally perform with just a laptop with Traktor and a DJ controller.
I would like to add my ipad to the set and I bought Audiobus, DM1, Turnado and ToushOSC. I also downloaded a bunch of apps like Analogue and TweakyBeat. I'm getting a midi keyboard in a few days (m-audio or something like that) to plug it in my ipad.
What I want is to get midi clock from an independent app (midibus?) to keep all my Ipad instruments and Traktor synced.
Whhich one i pick? Midibus? MidiBridge?

Hi jayfc, MidiBus will generate clock signal and send to apps and hardware simultaneously so that's what you need for that. MidiBridge on the other hand is more of a tool for managing MIDI routings and filtering to/from apps and devices that can be recalled using the UI or program changes from a keyboard. Many live performers use MidiBridge to manage their sets. Regards, Nic. |

Thanks for your quick answer!
I guess I'll get both of them, because I want to make a custom layout in ToushOSC to manage DM1, Turnado in a simple layout. I understand that I can do it through midibridge, right?

Hi jayfc, Not so fast! Only invest in MidiBridge if you have a definite need would be my advice. Most apps can now talk to each other using virtual MIDI so your TouchOSC template should be able to control DM1 without MidiBridge. Where MidiBridge can become useful is when you want to switch between multiple MIDI routings. I'd say start with the basics and then once you have that figured out you'll know if MidiBridge will be of use to you. Regards, Nic. |

Ok. I'll let you know how it all works once I set it up. If it does what I have in mind, it's going to be awesome!!
Thanks for your time!
Cheers

Ok, I'm back from testing. And the big problem is with Traktor. Bpm goes up and down like crazy, it's not steady at all. I read somewhere that Traktor takes like 15 seconds to follow external midi clock. But bpm goes up and down and it never hits the value I set in midibus. I am sending the signal through network session to rtpmidi in my laptop, then I configured a generic midi in port inside Traktor. It detects bmp value changes, but it never hits the exact bpm.
Any suggestions?

I got the solution, and it was very easy. I created an ad hoc network in my laptop and then connected my ipad to it. Now midi clock works perfectly.

Hi jayfc, That's interesting. This points to something in your wifi network that may be affecting the UDP packets that rtpMIDI uses to communicate. UDP by nature is a 'best-effort' protocol where packets are not guaranteed to arrive, so rtpMIDI builds on top of this by requesting retransmission of lost packets. Ultimately the retransmissions will cause jitter and an unreliable clock because they are much more time sensitive than other MIDI messages. It might be possible to tweak parameters in the wifi router, but if running ad-hoc solves the problem, I would continue with that. Thanks for sharing this. Regards, Nic. |

Hi again, I run some heavy tests and things work smoothly now. Midibus rocks!!!!!
