CME WIDI Master

You just need the app on android or ios to make the first update. After that it just work out of the box, you connect and zap everything working fine. Automatically connects to any other CME blue tooth and appears in your daw as a blue tooth midi.

I have not tried this in trhe wild but in non audience situations ( no bluethooth chaos with people with phones ) but it works great
PS .... used with reaper .... you can have reaper route the midi out back to the midi in .... one device covers my entire pedal board ( midi out from maincontrollervia WIDI .... reaper sends that out back to midi IN on WIDI .... which chains to all my FX ..... without reaper .... you need 2 devivces for midi in / out to same devices

There is no midi connection with a zero latency so yes there is a little, but wire free playing is covering that for my part :) If you're not too far from the source it works perfect! If not it still works but the latency increases ofcourse... I actually performed with it on a big stage and it worked without a problem..

I have 3 Widi Master pieces but I can’t trust any of them! They crash all the time!! The best choice is Quicco Sound only. I use Mi.1 1st & 2nd generation always live and I never had any problem at all!!!

easy to use connect to your equipment and control parameters with a Genki ring, or connect to your pc or other blue tooth kit

I use these to wirelessly change presets on my synth from my tablet during live gigs, so I'm definitely not using them to their full potential. Still, I have no idea how i lived without them before.
They practically live on my synth, so i can't really comment on long-term durability, but i've never had any problems with them.

No more cables, works well and is easy to setup

I notice no latency. Setup was easy. Works well with linux if blueman is installed. With older macs, it cannot connect automatically but you have to go into the midi device manager. Works with android as well. Only thing that could be improved is perhaps that the cable connecting the two subdevices could be a bit longer.

I connected with piano Yamaha YDP-S30 and works great with iPad.
