OnSong, BeatBuddy, Boss VE-500 via MIDI

Is anyone using a setup similar to this? Does it work, at least theoretically?

I would like to send MIDI commands via OnSong (iPad) to a BeatBuddy and a Boss VE-500. Would like to do it via Bluetooth Midi to BB (connected to the BB Midi dongle), then (with a standard Midi cable) BB Midi out to VE-500 Midi In.

“Simple setup”: Ipad-- BT MIDI – BB MIDI IN – BB – BB Midi Out (cable)-- VE-500 Midi In.

I would like to send “simple” commands from OnSong, like “Change Song in BB”, and “Change preset effect” in VE-500, and go. Occasionally there could be a tempo change sent to BB.

I have read conflicting info about this. I just want to simplify things, like, select my song on OnSong on iPad, and all the necessary changes to occur in BB and VE-500 at the same time, without bending down. Also, if it is possible, to do it with only a receiving BT Midi dongle (like WIDI or Yamaha) and a regular cable as connections, nothing more. This means the BB would receive all commands from the iPad and “relay” or “let thru” the command(s) for the VE-500, via the same chain, via the cable…

Wiser minds, I invoke you, hehe. Hopefully it can be done. Better yet, someone is already doing this :slight_smile: .

Thanks in advance.
