Can I use hardware synths with iPad software

in General App Discussion

Hi guys,

TL;DR:

How to sync iPad + AUM with hardware synths?

Here is my question.

In my setup I have:

  • iPad Pro 1 + AUM
  • iRig HD2 (I want to replace it by Behringer UMC1820)
  • iRig MIDI 2 (for now out goes to Volca FM)
  • Korg Volca FM

And I want to incorporate Arturia Microfreak when I buy one.
Also I have a bunch of midi controllers connected thru usb 2.0 hub to iPad.

My goal is to create a live performance setup to have a good time with hardware and iPad for mixing + record midi for hardware without computer and DAW. On iPad I would like to use AUv3 drum machine inside AUM as well occasionally use some soft synths. For sure I want to use audio and midi effects.

Yesterday I did some tests and I faced an issues with midi signal which goes to Volca FM - weird sounds until restart playback in aum, desync. Then I dive the topic of sync hardware with iPad and for now it is not clear if that really possible to make hardware to be synced well with iPad.

I've found some posts that states iPad (master clock) + hardware is not a good solution. Additionally I've watched Haq stream on this topic where he complains about it a lot. He wants to buy hardware step sequencer to make it master sync.

My question, how can I solve that issue? Should I consider hardware sequencer? I need some kind of piano roll like atom or Photon AU to freely play and record midi loop (opposite to step sequencing). If I use hardware step sequencer should I stick with it for my melodies or can I still use Atom or Photon UI for hardware?

I'm kind of new for such complex topic and don't want to throw money and realize that this is not working, like I have situation now.

Thanks everyone.

    I recently set up a Volca Bass syncing with midi clock from AUM. I think I initially had the same problem as you describe, i.e., weird sounds, not really syncing. I was using the Mozaic plugin with the Midi Clock Tool script. @wim , author of the script helped me get things working.

    I think the problem was that the clock AUM sends is not real midi clock. AUM sends one clock signal for each beat, but the Volca is expecting 24 (or maybe 48) signals per beat (i.e., 24 or 48 "pulses per quarter note", or PPQN). Apps on ipad sync fine to clock sent at 1 PPQN, but external hardware will require the standard 24 or 48. @wim modified his script to send 24 PPQN and my Volca Bass seemed to sync up fine. If your problem is the same, you could solve it by using that Midi Clock Tool in Mozaic plugin to fix the clock signals AUM is sending. That script is available on patchstorage.com .

    Although it was syncing fine, I seem to recall my Volca was actually syncing at 1/2 the tempo that was set in AUM. If so, that means the Volca was really expecting 48 PPQN so you would want to change wim's script to fix that, a simple fix.

    Hi, thanks. I will definitely try this out. Maybe it will fix Volca issue I have at least.

    It might fix all your issues with hardware. Midi hardware in general would be expecting 24 PPQN, or some multiple of that that the Midi Clock Tool could be revised to send. The script could even be fairly easily changed to send different amounts of PPQN to different devices. Also, once the Volca is synced you may be able to sync other hardware devices with a patch cable from its 'sync out' jack. I think the Microfreak has a 'sync in' jack that could be used for this purpose.
